The single-shaft hydraulic shredder is mainly composed of a cutter rotor, shredding chamber, feeding system, hydraulic push-feeding system, power drive system, and electrical control system.
Working Principle: Material is loaded into the feed hopper and continuously pushed toward the rotating cutter rotor by a hydraulically driven ram. Moving knives and fixed counter-knives apply shearing, tearing, and squeezing forces. A bottom screen regulates the final particle size: correctly sized material passes through, while oversized material remains in the chamber for further shredding. Different screen apertures can be selected to customize the output size.
The dual-shaft hydraulic shredder is a low-speed, high-torque primary coarse shredding machine consisting mainly of a hydraulic power system, dual-shaft cutter assembly, heavy-duty housing, and intelligent electrical control system.
It commonly serves as the first stage in solid-waste processing lines. Intermeshing blades on two parallel shafts rotate in opposite directions, applying simultaneous shearing, tearing, and squeezing forces to reduce large feed material into smaller pieces suitable for downstream processing.
Single-shaft shredders are well suited to thick-walled hard plastics, while dual-shaft or anti-winding single-shaft configurations can be selected for films, woven bags, and fishing nets.
A dual-shaft shredder performs primary coarse shredding of whole tires or large rubber blocks, followed by screened single-shaft shredding when smaller, more uniform particles are required.
Hydraulic push feeding continuously compresses bulky paper, fabric, and low-density fiber materials into the cutter rotor. Anti-winding rotor designs help prevent yarn and fabric from wrapping around the shaft.
Dual-shaft primary shredding and single-shaft secondary shredding can be combined to process bulky furniture, mattresses, containers, and other oversized waste efficiently and consistently.
Enclosed, high-precision single-shaft systems can be integrated with pneumatic conveying or sealed ductwork for continuous processing where cleanliness and controlled output size are important.
The system automatically stops under overheating or overcurrent conditions, protecting the motor and supporting stable long-term operation.
Power is automatically disconnected when the hopper is opened, improving safety during cleaning, inspection, and maintenance.
Strategically positioned emergency-stop controls allow immediate shutdown during abnormal situations or accidents.
Integrated ground-fault protection disconnects the power supply when current leakage is detected, reducing electric-shock risks.
Warning lights and status indicators clearly display operating conditions, faults, and maintenance requirements.
One-touch startup and independent unit control simplify workflow management across different production-line configurations.
Hydraulic assistance controls chamber opening and screen lifting, reducing manual work and shortening cleaning and maintenance downtime.
The hydraulic pusher handles bulky drums, industrial containers, compressed film bales, large hollow items, and other oversized recycling materials.
Low-speed hydraulic drive produces high shear torque for difficult, high-hardness, and bulky materials.
Counter-rotating intermeshing blades pull and shear material from both directions, helping prevent winding and clogging when processing films, fabrics, and cables.
Heavy-duty external bearings, reinforced welded chambers, and dust- and water-resistant protection support long-term operation in demanding recycling environments.
