This industrial application profile outlines the crushing, continuous extrusion devolatilization, and high-capacity pelletizing engineering setup designed specifically for post-consumer and post-industrial rigid plastics recycling plants. It focuses on recovering rigid HDPE milk jugs, household chemical bottles, 200L chemical drums, PP injection-molded crates, battery casings, and e-waste ABS\/PS housings.<\/p>\n
Rigid post-consumer recycling facilities battle severe operational headaches: feedstocks arrive with unpredictable wall thicknesses, trapped moisture, residual detergents, and tramp metal contamination (screws, bottle caps, hinges). During extrusion, printed ink binders and residual organics break down into volatile vapors, causing foamed pellets with pinholes and low bulk density. Furthermore, high melt contamination requires continuous screen changing that halts lines and generates massive melt leaks. This application combines heavy-duty primary shredding, fine crushing with magnetic metal extraction, single\/twin-screw extrusion with multi-vent vacuum degassing, continuous hydraulic dual-piston screen changers, die-face water ring pelletizing, centrifugal dewatering, and linear classifier dedusting to produce dense, solid, odor-free recycled pellets.<\/p>\n","protected":false},"excerpt":{"rendered":"
