Screw onveyor omponent uide screws Screws can be configured for every application. The asic onveyor light and Pitch Type Section provides descriptions of various types of screws that can be used in a multitude of bulk material conveying and processing applications. The use of helicoid or sectional screws is dependent upon the requirements of the application and the needs of the end user. In general, helicoid screws are used in light to medium duty applications, and are more cost effective when compared to sectional screws. Sectional screws can be configured for almost every type of application with special features such as ribbon or cut-and-folded flighting. Sectional screws can also be manufactured from special materials such as R-235 or 316 stainless steel. Screw section length is also dependent upon the requirements of the application and the needs of the end user. Standard screw lengths and hanger bearings can be used where the bulk material is non-abrasive and free-flowing. Single length screws are recommended for abrasive, heavy industrial applications. Screws are available in right and left hand construction. Right hand screws are much more common and are recommended for almost every application. Spare parts are more readily available for right hand screws. The hand of a screw along with the direction of rotation of the screw determine the direction of bulk material flow. The diagrams below illustrate the direction of bulk material flow for both right hand and left hand screws when rotated clockwise or counter clockwise. The rotation arrows indicate the location of the motor and gear reducer. The direction of bulk material flow is reversed when the direction of rotation is reversed. right hand screw with the motor and gear reducer located on the discharge end pulls the bulk material toward the discharge end and rotates clockwise. left hand screw with the motor and gear reducer located on the discharge end pulls the bulk material toward the discharge end and rotates counter-clockwise. To determine the hand of a screw, observe the slope of the near side of the flighting. If the slope is downward to the right, then the screw is right hand. If the slope is downward to the left, the screw is left hand. 2

SHORT PITH, SINL LIHT Variable pitch, single flight screws have increasing pitch with every flight and are used in screw feeders to provide uniform withdrawal of free-flowing bulk materials from hoppers, bins or silos. STNR PITH, OUL IHT Short pitch, single flight screws have the pitch reduced to 2/3 of the diameter and are most commonly used in inclined and vertical screw conveyor applications. Short pitch is also used in some variable pitch screw feeder applications. HL PITH, SINL LIHT Standard pitch, double flight screws have the outside diameter equal to the pitch, very similar to standard pitch, single flight. second set of flights is added 180-degrees apart from the first set of flights to provide a more even discharge of bulk materials. STNR PITH, TPR SINL LIHT Half pitch, single flight screws have the pitch reduced to 1/2 of the diameter and are commonly used in inclined and vertical screw conveyor applications. 1/2 pitch is also used in some variable pitch screw feeder applications. Standard pitch, single tapered flight screws have a tapered outside diameter increasing from 1/2 to full diameter and are used in screw feeders to provide uniform withdrawal of free-flowing bulk materials from hoppers, bins or silos. 4

Screw onveyor omponent uide SI ONVYOR LIHT N PITH TYPS Standard Pitch, Single Ribbon light Standard Pitch, Single light with Paddles Standard pitch, single ribbon flight screws have a space within the flight and around the center pipe to minimize the collection and buildup of viscous and sticky bulk materials. Standard Pitch, Single ut light Standard pitch, single flight with paddles screws have adjustable paddles located between screw flights. Up to four paddles per pitch can be added for gentle and thorough mixing of bulk materials. Standard Pitch, Paddle Standard pitch, single cut flight screws are notched at regular intervals on the outer edge to promote mixing and agitation of bulk materials. Standard Pitch, Single ut and olded light Standard pitch, paddle screws have adjustable paddles located in a helix around the diameter of the center pipe. Up to four paddles per pitch can be used for aggressive mixing and controlled flow of bulk materials. Mass low Standard pitch, single cut and folded flight screws are notched at regular intervals on the outer edge and have lifting paddles to promote aggressive mixing and agitation of bulk materials. Mass flow screws utilize a combination of internal cone and variable pitch to provide increasing volume with every flight and are used in screw feeders to provide uniform withdrawal of bulk materials from hoppers, bins or silos. 5

Screw onveyor omponent uide ONVYOR SRWS: HLIOI VRSUS STIONL HLIOI LIHT SRW ONVYORS STIONL LIHT SRW ONVYORS Helicoid flighting is cold rolled from special steel into a continuous helix that produces a work-hardened, smoothly finished flighting surface. It is very cost-effective and provides superior strength with diameter, pitch and thickness closely controlled. Helicoid screws are manufactured by mounting helicoid flighting on a center pipe and fastening by intermittent welds. ontinuous welding on the carrying side or both sides is also available. Internal collars are inserted in each end and plug welded to accommodate shafts. Screws are structurally reinforced at the ends by end lugs. Sectional flighting is manufactured from steel plate and formed into a helix. Sectional flighting is available in heavier thicknesses than helicoid flighting and used in more abrasive applications. Sectional screws are manufactured by mounting sectional flighting on a center pipe, butt welding each flight together and fastening by intermittent welds. ontinuous welding on the carrying side or both sides is also available. Internal collars are inserted in each end and plug welded to accommodate shafts. Screws can be structurally reinforced at the ends by end lugs.

Screw onveyor omponent uide SRW ONVYOR SUR INISHS The surface finish of the interior and exterior of a screw conveyor can be very important to the success of the overall bulk material process. ertain bulk materials such as chemicals or food products require special finishes to maintain the integrity of the bulk material and prevent contamination. Understanding the bulk material process is very important to determining the proper surface finish of a screw conveyor. Most industrial applications such as conveying limestone, biosolids or offal require no special polishing of the welds, flights or pipe on the interior of a screw conveyor. Likewise, the exterior of a screw conveyor requires no special polishing of the welds or surfaces of the troughs, trough ends or covers. Pits and crevices are allowed at welded joints because the bulk material will not contaminate or corrode. Special industrial applications such as conveying food ingredients or specialty chemicals require special polishing of the welds, flights and pipe on the interior of a screw conveyor. ontinuous welding of the flights to both sides of the center pipe is typically required to eliminate any pits or crevices. The surfaces of the flights, welds and pipe are then polished to a specific grit finish to meet the requirements of the application. The exterior of a screw conveyor may require special welding and polishing of the troughs, trough ends and covers. No pits or crevices are allowed at welded joints because the bulk material could be contaminated or cause corrosion. The KWS screw conveyor surface finishes shown below address the needs of almost every bulk material application. Surface finishes are called out for the interior and exterior of a screw conveyor including the welds, flights, pipe, troughs, trough ends and covers. The KWS screw conveyor surface finishes are much more comprehensive when compared to the M surface finishes. KWS addresses the surface finish requirements of the welds, flights, pipe, troughs, trough ends and covers while M only addresses the surface finish of the welds on a screw conveyor. The M surface finish call outs are incomplete and can be confusing to the ustomer, possibly creating a problem. Our goal at KWS is to exceed the expectations of our ustomers by providing screw conveyors with the proper surface finish for the application and process. 13

Screw onveyor omponent uide KWS hardsurfacing for abrasive applications KWS provides screw conveyors manufactured from many commercially available abrasion-resistant materials. Metals such as R-235, R-400 and R- 500 plate are used in many abrasive applications. Hardsurfacing, also known as hardfacing, is the application of wear-resistant metals to the flight surface by means of welding. KWS hardsurfaced screws are designed to eliminate excessive wear on flights while conveying abrasive bulk materials. hardsurface alloy is typically welded to the carrying side of the flighting face. When handling extremely abrasive bulk materials such as glass cullet or wood bark, the non-carrying side and outside diameter of the flight as well as the outer surface of the center pipe can be hardsurfaced to prevent wear of the softer base materials. Hardsurfacing materials manufactured by Postle Industries, llied Welding and Stellite are commonly used by KWS. Many other hardsurface alloys are available. The chart provided shows the standard width of hardsurfacing for a specific screw conveyor diameter. Please consult KWS ngineering or your KWS Salesperson to determine the best solution for your application. dditional consideration must be given to selecting the proper coupling shafts and hanger bearings for an abrasive application. Hard iron bearings and hardened coupling shafts are sufficient for most moderately abrasive applications such as handling crushed limestone or Portland cement. or severely abrasive applications such as handling alumina or flyash, Stellite sleeved bearings and couplings shafts are typically required.

Screw onveyor omponent uide hangers Hangers are intermediate support brackets located between screw sections along the length of a screw conveyor. Hangers allow for the use of multiple screw sections. Many different hanger styles are available, depending on the application. Style 216 and 226 hangers are the most widely used and are in stock at KWS. Hangers are generally used when conveying non-abrasive and free-flowing bulk materials. The bulk material must be able to flow around the hanger. Hangers are not recommended when conveying abrasive and sluggish bulk materials.

Screw onveyor omponent uide hanger bearings Hanger bearings provide a bearing surface to support a screw section when multiple screw sections are used in a screw conveyor. Hanger bearings are journal or plain type bearings that mount in hangers and are replaceable when worn. Many different hanger bearing materials are available, depending on the application. Style 216 and 226 bearings are the most widely used and are in stock at KWS. KWS hanger bearing recommendations are listed in the omponent Series Table of the KWS Screw onveyor ngineering uide for the specific bulk material to be conveyed.

(i.e: TTO92U-SK3-R) without foot Trough ends without feet are typically used in applications where a screw conveyor is suspended above ground and is supported from the top flange. with foot Trough ends with feet are the most commonly used type of trough end, and are typically used in applications where a screw conveyor is mounted directly to the floor or on structural supports. 28

Screw onveyor omponent uide trough ends Pedestal Pedestal trough ends are typically used in heavy and extraheavy duty applications where a split gland, flanged gland or mechanical seal is required. Pedestal trough ends require the use of a pillow block bearing. The space between the trough end and pillow block bearing prevents contamination of the bearing. lush nd lush nd trough ends are used with flush end discharge spouts where overall length needs to be minimized and conveyance length needs to be maximized. The bottom flange of the flush end trough end is drilled to match the discharge flange pattern. ulkhead ulkhead trough ends are used with flange mounted gear reducers on the drive end of a screw conveyor and are typically used in heavy and extra-heavy duty applications where a split gland, flanged gland or mechanical seal is required. The space between the trough end and bulkhead prevents contamination of the gear reducer. bulkhead drive shaft is required. Torque rm Torque arm trough ends are used with pillow block bearings and shaft-mounted gear reducers on the drive end of a screw conveyor and are typically used in heavy and extra-heavy duty applications where a split gland, flanged gland or mechanical seal is required. The space between the trough end and pillow block bearing prevents contamination of the bearing and gear reducer. The special torque arm design allows the gear reducer to float freely on the drive shaft. torque arm drive shaft is required. 29

Screw onveyor omponent uide nd earings nd bearings provide support at one or both ends of a screw conveyor and must be designed to handle radial and thrust loads as well as shaft runout. Radial load as measured at the end bearing is half the weight of the last screw section. Radial loads act at right angles to the shaft centerline or bearing axis of rotation. Radial loads are typically negligible at the screw conveyor end shaft. However, end bearings located at the drive end of a screw conveyor are subject to higher radial loading due to the weight of the gear reducer and motor or overhung loads from chain and sprocket drives. Thrust load is the reaction through the conveyor screws from the movement of a bulk material. Thrust loads are also called axial loads and act parallel to the shaft centerline or bearing axis of rotation. The end bearing on the drive end must prevent axial movement of the screw. ny axial movement of the screw could allow contact with the hanger bearings or trough ends. KWS recommends locating the drive unit and thrust bearing at the discharge end of a screw conveyor, placing the screws in tension and preventing misalignment when the conveyor is heavily loaded. NOMNLTUR = nd earing = lange P = Pillow lock Shaft runout occurs when the shaft rotates in an eccentric pattern about the centerline axis. Shaft runout is caused by the minor amount of bend inherent in any screw due to the manufacturing process. Shaft runout must be accounted for at the bearings to avoid premature bearing failure. KWS recommends using a fixed thrust bearing at the drive end and a ball or spherical roller bearing at the tail end. 1 1 2 b b Shaft iameter 1 = 1 3 = 112 = 1-1/2 3716 = 3-7/16 2 = 2 31516 = 3-15/16 2716 = 2-7/16 4716 = 4-7/16 = all earing R = Roller earing langed Roller earing langed roller bearings are mounted directly to standard trough ends on the drive end of a screw conveyor.

Screw onveyor omponent uide shafts Shafts are designed to transmit rotation and torque between individual conveyor screw sections and provide radial support at the hanger bearings and trough ends. Shafts are manufactured from cold-rolled -1045 carbon steel as well as 304 and 316 stainless steel; other materials are available upon request. old-rolled -1045 carbon steel shafts are adequate for most applications. However, high-tensile strength materials such as -4140 may be required for specific applications. Stainless steel shafts may be necessary when corrosive or contaminable materials are to be conveyed. Using a combination of N and specially-built jigs, KWS shafts are manufactured to the tightest tolerances available and ensure perfect bolting alignment. Shaft size is determined based on full motor torque of the drive assembly and the materials of construction of the shafts. old-rolled -1045 carbon steel has a yield strength of 45,000 psi. 304 and 316 stainless steel shafts have a yield strength of 30,000 psi. Please refer to the ngineering Section of the KWS ngineering uide for further information on shaft selection. significant safety factor is included in the shaft design calculations. or information regarding the weights of each shaft, please contact KWS ngineering. oupling Shaft oupling shafts transmit rotation and torque between screw sections. learance is provided between the screw sections for a hanger and hanger bearing support. Hardened shafts are required for hard iron hanger bearings. lose oupling Shaft lose coupling shafts transmit rotation and torque between screw sections. The screw sections are butted together with no clearance and clocked to form one continuous helix. lose coupled screws are supported by a wear liner or wear bars that are welded into the trough sections. nd Shaft nd shafts support the tail end of the screw section at the non-drive end of the screw conveyor. nd shafts are typically the same diameter as the coupling and drive shafts. nd shaft length is dependent on the type of end bearing, seal and trough end. 45

Screw onveyor omponent uide troughs KWS designs and manufactures many different types of troughs and tubular housings for every bulk material handling application. ll troughs and tubular housings are available in carbon steel construction as well as abrasion-resistant steels, hot-dipped galvanized and stainless steel. KWS can manufacture troughs and tubular housings out of any commercially available metal. Plate end flanges are N cut and jig-welded to ensure exact alignment with adjacent trough sections. KWS recommends supporting every trough section with flanged feet or saddles.

The U trough design is simple, economical and provides access for maintenance. ngle lange ngle flange troughs are manufactured with structural angle top flanges to provide extra rigidity. Stock angle flange troughs utilize thinner gauges of metal and are typically used in light and medium duty applications. ormed lange ormed flange troughs are manufactured with formed top flanges. Stock formed flange troughs utilize heavier gauges of steel and are typically used for medium to heavy duty applications. ormed flange troughs are dusttight. 53

Screw onveyor omponent uide troughs ouble ormed lange ouble formed flange troughs are manufactured with two formed top flanges for added rigidity. ouble formed flange troughs provide an effective dust-tight seal when used with flanged covers and a compressible gasket material. ormed hannel ormed channel troughs are manufactured with two formed side channels to provide rigidity for spanning long distances without intermediate supports. The lower, curved trough section is typically bolted to the channel sides and can be replaced when worn. rop ottom rop bottom troughs are manufactured with a removable or hinged lower curved trough section. rop bottom troughs allow access to the screw for clean out or maintenance purposes. Removable drop bottom troughs are bolted on close spacing on both sides of the trough. Hinged drop bottom troughs are hinged on one side with quick-release clamps and safety bolts on the other side. Jacketed Jacketed troughs are manufactured with an outer jacket that is seal-welded to the trough. ulk materials can be cooled, heated or maintained at a constant temperature with jacketed troughs. Heat transfer mediums such as water, hot oil or steam flow through the jacketed trough to provide heat transfer. SM coded troughs are available from KWS. LR TROUH lared troughs are manufactured with formed top flanges. The top opening of a flared trough is wider than a U-trough to allow sticky or viscous bulk materials to enter the trough easier. Many mixing screw conveyors utilize flared troughs because the additional space above the screw creates more room for bulk materials to be mixed. 54

Screw onveyor omponent uide troughs TUULR HOUSINS Tubular housings are typically used when a screw conveyor is inclined over 15-degrees. onveying efficiency is greatly improved with tubular housings because bulk materials are contained and fall back is reduced. Tubular housings are also used for weather-tight applications and used to hold internal pressure in a screw conveyor. SM coded tubular housings are available from KWS. Non-Split Non-split tubular housings are manufactured by rolling a cylindrical tube and continuously welding at the seam or cutting down spouting or pipe to length. Split Split tubular housings are manufactured by rolling two halves and forming flanges on each side. The two halves are then bolted together to form a rigid assembly. RTNULR troughs Rectangular troughs are typically used in applications for conveying abrasive bulk materials. The space between the screw and rectangular trough fills with the bulk material being conveyed forming a static layer. The bulk material being conveyed slides over the static material and eliminates wear on the rectangular trough. Rectangular troughs are also beneficial when utilizing certain abrasionresistant steels such as R-400, R-500 and chromium carbide steel due to their low formability. ngle lange ngle flange rectangular troughs are manufactured with structural angle top flanges to provide extra rigidity similar to U-troughs. ormed lange ormed flange rectangular troughs are manufactured with formed angle top flanges similar to U-troughs. ngle lange -Top & ottom ngle flange top & bottom rectangular troughs are manufactured with structural angles on both the top and bottom flanges. Some high strength steel plate materials such as R-400 cannot be formed at 90-degree angles and angle flanges are required. ormed lange -Top & ottom ormed flange top & bottom rectangular troughs are manufactured with formed angles on both the top and bottom flanges. 55

Screw onveyor omponent uide discharge spouts ischarge spouts are typically located at one end of a screw conveyor on the bottom of the trough. ulk materials exit a screw conveyor through the discharge spout. Multiple discharge spouts with slide gates can be used to distribute bulk materials to various downstream processes. Slide gates should not be used on the final discharge of a screw conveyor because if the slide gate is closed, bulk materials will be compressed against the trough end and cause damage to the screw conveyor.

The discharge is considered flush with the trough end. Hand Slide hand slide gate is the simplest form of slide gate and utilizes a slide plate, spacer and retainer flange bolted to a standard discharge spout. Open nd Open end discharge spouts utilize a hanger, hanger bearing and end shaft to allow bulk materials to discharge out the end of a screw conveyor. Open end discharges allow for maximum conveying distance over the length of the trough. 71

Screw onveyor omponent uide covers overs are placed over the trough and fastened in place to provide a IX enclosure for the bulk material and to provide protection for personnel operating and maintaining the equipment. Standard cover lengths are 10-feet for 4, 6, and 9-inch diameter screw conveyors. Standard cover lengths are 12-feet for screw conveyors 12-inch and larger in diameter. KWS recommends bolting all covers on close centers to prevent access to the screw during operation.

KWS does not recommend the use of flat covers because flat covers can easily slide off the top of a screw conveyor and cause injury to personnel. KWS recommends bolting all covers on close centers to prevent access to the screw during operation. 74

Screw onveyor omponent uide covers Semi-langed Semi-flanged covers are manufactured with a slight formed flange on each side to provide some rigidity. KWS recommends flanged covers in place of semi-flanged covers in most applications. over sections are typically secured using spring clamps. KWS recommends bolting all covers on close centers to prevent access to the screw during operation. Hip Roof Hip roof or ridged covers are manufactured with a center peak for outdoor applications. Snow or rain runs off the hip roof cover similar to a roof on a house. ormed flanges on both sides of the cover provide extra rigidity. KWS recommends bolting all covers on close centers to prevent access to the screw during operation. shroud Shrouds are manufactured to fit in U, flared or rectangular troughs and create a tubular cross section for screw feeders and steeply inclined screw conveyors. Standard covers can be used with shrouds. Shrouds are bolted on both sides of the trough for easy removal and include an integrated batten bar. 75

Screw onveyor omponent uide drive arrangements KWS utilizes a variety of drive arrangements and gear reducer manufacturers. ach drive arrangement shown below provides unique advantages for specific applications. KWS designs each drive with a minimum of 1.4 service factor (lass II) to ensure long life and reduced maintenance. Spare parts are available through authorized power transmission distributors all across the U.S. and anada. Screw onveyor drive Screw conveyor drives are the most common drive arrangement utilizing a screw conveyor adapter that bolts to the trough end of a screw conveyor. The gear reducer is flange mounted directly to the trough end to provide a simple, rigid assembly. ulkhead ulkhead trough ends are used in applications where there is a need to locate the drive away from the trough end. When conveying bulk materials at high temperatures, the drive must be located away from the source of heat to prevent drive failure. lso, if a special shaft seal is required, bulkhead trough ends provide clearance for the seal. langed gland, split gland and mechanical seals are typically used with bulkhead trough ends. Torque rm Torque arm trough ends allow shaft-mounted reducers to float to handle shaft run-out. pillow block bearing is required to support the screw when using a torque arm trough end. Similar to bulkhead trough ends, torque arm trough ends are used in special applications where there is a need to locate the drive away from the trough end. langed gland, split gland and mechanical seals are typically used with torque arm trough ends. 84
