TRADE SHOW PREVIEW PET planet Insider Vol. 19 No. 05/18 www.petpla.net 60 PET recycling equipment at NPE 2018 Herbold Meckesheim USA will have a signicant presence in Orlando. They offer a complete line of plastics size reduction and wash line products for use with PET. West Hall, Level 2, 7545 SB series granulators with screw feed A force fed granulator for size reduction of PET bottles, the model SMS 100/160-9-2 SB3 features a rotor that is 20% larger. The additional size and mass of the rotor allows the granulator to operate at higher throughput rates (up to 7t/h). Material is fed into the destruc- tion chamber via a patented screw fed mechanism that utilises three verti- cally mounted feeding screws. This feeding method is intended to offer several advantages over gravity feed- ing including consistent, even feed rates, reduced power consumption, no material yback, quiet operation, less wear on the cutting chamber, and reduced nes and dust. The unique knife geometry which positions inclined rotor and stator knives at the same, but opposing angles provides a true double cross cutting action. HB series granulators with ram feed HB series granulators combine the best attributes of a shredder and a granulator for semi-automatic plastics recycling, states the company. They efciently reduce bulky items all the way down to particles 0.16 to 0.31 inches in diameter without any sec- ondary size reduction. The HB series granulator has a powerful rotor with double-cross cut- ting action, a heavy-duty hydraulic ram, and a large feed hopper that can handle whole bales, cut-open lm rolls, mingled packs of sprue spiders, thick-walled purgings, carpet waste, pipes and proles, post-consumer bot- tles, and whole containers/crates with- out the need for dosed feeding or the risk of jams in the cutting chamber. Once the hopper is lled, the unit can be left unattended as the ram intermittently breaks pieces off the bottom of the load and pushes them into the cutting chamber. The particles produced are ready for further use. This one-machine size reduction also reduces electricity consumption and simplies cleaning, colour changes, material changes, and maintenance. The HB series granulator, con- structed of sturdy welded steel, is available in four models with two rotor diameters (23.6” and 31.5”), four working widths (39.4” to 63”), four drives (45 to 200kW), and four throughput rates (0.5 to 6t/h). The design of the cutting chamber allows easy access for cleaning. The place- ment of the rotor bearings on the out- side of the unit keeps nes out of the bearings and grease out of the prod- uct. Different rotor types are available. Energy saving HVT series dryer HVT series centrifugal dryers pro- vide gentle energy saving drying of regrind, especially hollow bodies, PET bottles, polyolens and other plastics. The HVT’s distinguishing feature is its vertical rotor shaft, which ensures longer dwell time in the drying cham- ber. This vertical design offers the added advantage of signicant space savings versus horizontal systems. The renement of the HVT’s inter- nal geometry, including the rotor and housing minimises the occurrence of nes and allows for greater yield. HVT dryers operate on the principle of centrifugal drying. Material is acceler- ated against a screened stator sur-
