Large extruder purgings, reject parts, trim scraps, synthetic fibers, and baled or loose film are some of the plastic waste that can be processed by a new line of stand-alone grinders and turnkey recycling systems. The RG62 K from Vecoplan (High Point, NC) has a large hopper in-feed opening measuring 63 by 80 inches, which allows up to 6.3 cubic yards of material to be dumped into the unit and processed at the push of a button, for what Vecoplan calls "true dump and run operation." The system's cutting chamber is fed by a two-speed, 10-hp, hydraulic ram, which pushes scrap into the cutting rotor. The

rotor measures 15 inches in diameter and has 45 40-by-40-mm cutting inserts, which are bolted onto holders welded into impressions machined in the rotor surface. Each cutting insert can be rotated to four separate wear points prior to replacement, minimizing maintenance costs. The RG62 K is available with drive motors ranging from 75 to 150 hp, propelling the rotor at 120 rpm. The cutters are interlaced with a serrated counter knife that's bolted to the bed of the cutting chamber, with Vecoplan saying the design provides precise cutting and increased durability. Once cut, material exits the cutting chamber through a heavy-duty industrial sizing screen, available with openings from 3 inches to 3/8 of an inch. The screens are easily removed to alter the size of particulate captured.
