scrap.CMG Granulators has introduced a new in-line granulator series for thermoformers, suitable for use with scrap sheet, skeletal sheet and reject parts. The new GT series comprises four models, suitable for small to medium capacities, to cover applications ranging from 200 to 1,000 kg/h. The company highlights the blade set-up
design: “The rotor blades are positioned at a high degree of inclination, 50°, in respect to the bed blade, so to guarantee the best cutting precision, the highest dimensional homogeneity of the regrind, the lowest sound emissions and absence of powder.” The cutting chamber does not utilise cast or welded components but is “bolt and dowel” assembled. Energy usage is 20 Wh/kg, compared to over 40 Wh/kg that a conventional unit con- sumes, says CMG. The GT models are low profile to be positioned underneath the finished product conveyor belt. Conair says that its redesigned ScrapSaver fluff

feeder offers higher film scrap capacity and better reclaim efficiency. The device feeds granulated film scrap (fluff) into a stream of virgin material, which is then delivered to an extruder for processing. Designed for use with in-line granulation systems, the latest version has a larger main hopper and top plate – for greater fluff surge capacity. It also boasts an improved auger and auger shaft – to deliver higher fluff-to-virgin ratios to the extruder. The twin-chamber hopper holds granulated film
fluff in a large main chamber and virgin material in a smaller side chamber – keeping both separate until just before they are introduced into the screw flights. To prevent fluff from bridging, the new unit uses a longer, stronger one-piece auger that can drive higher fluff re-feed ratios to the extruder throat. The ScrapSaver unit mounts, via an adapter, directly to the extruder feed throat.
Extruded thermoplastic elastomer edge trims can
be efficiently recycled with Getecha RotoSchneider granulation technology. In this context, Getecha pro- vided its RS 2402-E granulator as a solution for a

customer that manufactures drive belts and conveyor belts which needed to grind TPE and TPU edge trim. Tailored to the special requirements of the customer, the RS 2402-E was equipped with 4 kW drives, which give the infeed mills a crushing capacity of up to
80 kg/h of regrind. The RS 2402-E has a two-part funnel in front
of the infeed opening which enables two edge trims to be fed into the roller infeed at the same time, without them crossing over. It also has an intelligent controller for regulating the infeed speed, which also includes an automatic switcho- ver to buffer mode. If the feed speed falls below the minimum, the control system developed by Getecha prevents the formation of disruptive fine material and unwanted dust particles.
