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.

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.
