SCC screen classifying cutters were specified by a major sheet extruder and thermoformer to downsize edge trim and other scrap for reuse in process operations.
Edge trim from calendering line is pneumatically fed through tube at bottom of machine to SCC screen classifying cutter in adjacent sound enclosure. Trim is downsized and reused in calendering process.
Scrap from thermoforming is collected and conveyed to granulators.
Tube installed at the top of rotor enclosure (left) feeds edge trim to screen classifying cutters for downsizing.
SCC cutters utilize a helical rotor with dozens of tungsten carbide-tipped teeth attached to an array of staggered holders. The rotor downsizes scrap against twin bed knives in a steady, even cutting action that reduces fines and other imperfections.
SCC cutters produce granulate of consistent size and properties.
