6 SRWS 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

17 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

20 KWS HRSURIN OR RSIV PPLITIONS 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.

N RINS 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.

46 N RINS 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 Shaft iameter 1 = 1 3 = 112 = 1-1/ = 3-7/16 2 = = 3-15/ = 2-7/ = 4-7/16 = all earing R = Roller earing LN ROLLR RIN langed roller bearings are mounted directly to standard trough ends on the drive end of a screw conveyor.

The U trough design is simple, economical and provides access for maintenance. NL LN 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. ORM LN 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

58 TROUHS OUL ORM LN 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. ORM HNNL 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. JKT 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

59 TROUHS 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 TROUHS 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. NL LN ngle flange rectangular troughs are manufactured with structural angle top flanges to provide extra rigidity similar to U-troughs. ORM LN ormed flange rectangular troughs are manufactured with formed angle top flanges similar to U-troughs. NL LN -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. ORM LN -TOP & OTTOM ormed flange top & bottom rectangular troughs are manufactured with formed angles on both the top and bottom flanges. 55

88 RIV RRNMNTS 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. SRW ONVYOR RIV 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. ULKH 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. TORQU 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
