1 Pelletising Systems 0 Underwater pelletising systems for up to 5,000kg/hr Our modular pelletising systems are highly cost efficient & cover a wide range of applications: Primary pelletising Masterbatch production Compounding Plastics recycling Our pelletising systems are used worldwide to process a wide variety of polymers, from low viscosity engineering plastics to high viscosity materials such as gum bases. The typical pelletising system consists of three main components: Pelletiser Tempered water system (TWS) with centrifugal dryer Electrical control & power supply The pelletising system interfaces with the extruder or melt pump. The pelletising process is performed in a closed loop system. The pelletised product is conveyed by the water flow from the cutting chamber into the centrifugal dryer. During the process, the pelletised product has no contact with ambient air, & there is no risk of gas, dust emission, or contamination of the product. The process water remains in the tempered water system, another advantage which contributes to the environmental compatibility of this process. The special benefits of underwater pelletising systems are: Low space requirement due to compact design Low noise emission High economic efficiency Less cleaning effort required in case of product changes Simple access to die plate & cutter hub with replacement possible within 5-20 minutes Production of standard pellets & micropellets (0.2 to 2mm) All systems are backed by around-the-clock technical support Telford Smith offers complete extrusion & pelletising systems for a wide range of materials. Strand pelletisers Four models to choose from for 2 to,000 kg/hr and suitable for processing most thermo plastics materials. Features include: One piece solid tool steel rotary cutter Solid tool steel fixed blade with four cutting edges AC or DC variable speed drive on request Pneumatic clamping of polyurethane roller Variable pellet length available on request Stainless steel or aluminium contact parts throughput Low noise emission Alternative discharge heights on request Moulding & Recycling page 2 Tuesday, 5 December :36

Machines may be customized for various applications: Special feed systems are available, including feed hoppers with bypasses for long parts & suction systems with optional dust & metal separation devices GS granulators are often used in combination with shredders in a two step size reduction system. All machines in the GS range produce a high quality granulate for injection moulded articles, sprues, pipes, profiles, sheets, or film. The machines are economical, reliable, easy to clean & have a long service life. We also offer a wide range of optional accessories such as blowers, suction systems, conveyor belts, metal detectors, fines separators etc. Range of feeding options Horizontal feeding hoppers for pipe & profiles Roller feeding devices for skeletal sheet, solid sheet & edge trim Hoppers for long parts, rolled sheet or voluminous parts Force feed systems for bottles Conveyor belts with optional metal detectors or magnetic rollers Superior cutting action V cut rotor design for optimum cutting performance. Granulators are generally equipped with V cut rotors. The V arrangement of the rotary cutting knives holds material in the centre of the rotor, reducing wear on the side walls & the tendency of material to plasticise. The V design is also beneficial in that blade wear is more even & bearing load is equally distributed. Depending on application, Granulators may also be equipped with single scissor cut rotors. The efficient cutting action of scissor cut rotors ensure clean cut granules, less fines & reduced noise emission.

6 Low Volume Shredders 5 T h e e c o n o m i c p r e - s h r e d d i n g s o l u t i o n The ZBS shredder has been developed as an economical alternative to the ZSS shredder range. The main application is shredding, prior to granulating, of small lumps commonly accrued in injection processes during color changes & start up. The machine is fed via a double walled sound dampening hopper which can be turned in 3 directions to easily adapt to existing installations. Different material discharge options are available e.g. open outlet to feed into bins, suction troughs to connect to a blower system, direct transfer into another machine or onto a conveyor. Hopper & discharge design can be tailored to accommodate specific needs. The cutting chamber is designed with a strong tangential in-feed thus eliminating the need for a hydraulic feeding system. The 30 mm diameter 'E' style rotor which is directly driven by a heavy duty geared motor ensures smooth operation.

ZSS shredders feature heavy duty, dual speed hydraulic systems together with integrated PLC controls. The shredder rotor is equipped with special knife holders that secure the square cutter blocks.

Depending on material type & the final size required by the customer, various types of cutters & screens are available.

7 Single Shaft Shredders T h e c l e v e r s h r e d d i n g s o l u t i o n The ZSS series of single shaft shredders are designed to withstand the demands of continuous operation in recycling a wide range of materials including: loose & baled film, purgings, automotive bumper bars, & timber scrap. ZSS shredders feature heavy duty, dual speed hydraulic systems together with integrated PLC controls. The shredder rotor is equipped with special knife holders that secure the square cutter blocks. An efficient cutting design ensures a clean cut & reduces heat build up. Cutting knives may be turned up to four times to utilise the four cutting edges prior to sharpening. Depending on material type & the final size required by the customer, various types of cutters & screens are available. Various rotor designs Unique hardened alloys for demanding applications Adjustable knife height to suit specific material & application Bolted knife holders for simplified maintenance procedures & reduced down time The ZSS shredder can be equipped with various rotor designs. This flexibility of design facilitates processing of all types of materials. The rotors can be modified to suit special applications. The rotors in the ZSS shredder are equipped with square cutter blocks. These cutters make light work of the heaviest application. Importantly, the design allows efficient cutting of material, rather than hammering, which reduces heat built-up & degradation of material. The cutter blocks have four corners so they can be easily rotated when the cutting edge is worn away. In feed & out feed conveyors may be integrated with shredders on request.

8 Heavy Duty Shredders 7 Heavy duty swinging ram with over sized bearings T h e h i g h t h r o u g h p u t s h r e d d e r The ZXS series of shredders are built tough for high throughputs & demanding applications. Standard shredders having rotor widths of,500mm through 3,000mm use 750mm diameter cutting rotors. ZXS shredders are well suited to size reduction of a range of materials from voluminous tanks to solid purgings. A large rotor diameter in combination with slow rotational speed ensures smooth operation. Easy access doors combined with an optional hydraulically actuated screen cradle ensure easy access for maintenance & cleaning. Throughputs up to 0,000 kg/hr can be expected. Swinging ram ZXS shredders are equipped with a hydraulic feeding system. The heavy duty swinging ram is equipped with heavy duty bearings & supports. The swinging ram is equipped with a serrated ram plate to minimise slippage when shredding bulky items such as bundles, lumps or pallets. To eliminate material build up between the pusher & cutting chamber, the pusher is equipped with scrapers. The hydraulically operated ram forces material against the rotor & in the event there is an overload situation, the ram will stop & then move backwards to release pressure on the rotor. The ram then automatically reverts to the forward pushing motion & in this way throughput is optimised. The special swing ram design eliminates the need for guide rails inside the cutting chamber, reducing wear & the risk of the pusher jamming. The swinging ram design also reduces the footprint of the machine. Standard shredders are equipped with two speed hydraulic systems allowing the ram to move faster in a no load situation. ZXS shredders are an integral part of any recycling system. In feed & out feed conveyors are available on request.
