The Plastic Shredder series delivers heavy-duty, low-speed, high-torque primary size reduction for oversized, dense, and bulky polymer waste that cannot be processed directly by conventional high-speed granulators. Operating at controlled rotational speeds (typically 60 to 100 rpm on single-shaft units, and 15 to 35 rpm on twin-shaft units) with tremendous cutting torque, our shredders cleanly shear through solid extruder purgings, thick-walled pipes, 200-liter drums, and tightly baled films without blade stalling, high-speed impact noise, or excessive dust generation.<\/p>\n
To address diverse physical scrap geometries and processing requirements, the series is engineered around two distinct mechanical architectures:<\/p>\n
Designed primarily for dense solids, solid lumps, and thick-walled scrap. Features a solid alloy steel rotor fitted with 4-way indexable concave cutter knives, an intelligent proportional hydraulic pusher ram, and a hardened-tooth-surface helical gear reducer. The horizontal hydraulic ram continuously advances bulky scrap into the cutting rotor under load-sensing control. Discharged scrap passes through an interchangeable bottom sizing screen (typically 30 mm to 60 mm), guaranteeing uniform fragment sizing ideal for direct infeed into secondary granulators or wash lines.<\/p>\n
Engineered for high-volume hollow containers, voluminous moldings, and bulky flexible scrap. Utilizes two counter-rotating hexagonal shafts equipped with interleaved multi-claw alloy cutter discs. Powered by independent dual motors and heavy-duty gearboxes, the twin shafts grab large hollow bodies\u2014such as 200L chemical drums, 1,000L IBC totes, automotive bumpers, and film bales\u2014pulling them into the cutting chamber and tearing them into coarse strips (40 mm to 100 mm) without requiring a hydraulic ram or discharge screen, completely eliminating screen binding and clogging.<\/p>\n
Both single-shaft and twin-shaft models integrate smart Siemens PLC automation with continuous current and pressure monitoring. Upon encountering unyielding foreign obstructions or sudden torque surges, the drive automatically reverses rotation and modulates material feed to clear the cutting zone, ensuring safe, continuous, and jam-free industrial operation.<\/p>\n","protected":false},"excerpt":{"rendered":"
