Williams Ripshear® Shredders feature a slow speed, high torque, disc cutting action that reduces solid wastes quietly, cleanly, and economically with minimum vibration. These shear slow-speed shredders can be used to reduce a wide variety of materials including tires, wood waste, wallboard, municipal solid waste, batteries, corrugated papers, 55 gallon drums, fabric, industrial plant and hospital waste, furniture, light metal scrap, and much more. For reject wallboard processing, for example, the Williams Ripshear® Shredder can quickly and efficiently reduce large bundles of reject wallboard to minus 6” (150mm).

There are multiple ways to shred material, such as tearing and fracturing. The Ripshear Slow-Speed Shredders offered by Williams involve shearing, which is actually cutting the material like scissors. Williams has created a patented technology that is versatile across multiple applications.

Williams offer two types of Ripshear® slow-speed shredders: Hydraulic Shredders and Electric Shredders. See more about our slow-speed shredders below.

A Heavy-Duty Hydraulic Shredder

Hydraulic Ripshear Shredder - Williams Patent CrusherAdvantages of this hydraulic shredder include:

Williams Ripshear® Shredders are built for heavy-duty applications and are easy and inexpensive to install. Only a minimal foundation of normal concrete slabs or equal leg support is required to support these shear shredders. The shearing action of these slow-speed, hydraulic shredders is quiet and creates little or no dust.

An automatic unjamming action through rotor reversal and resetting minimizes shutdowns and maintenance, making them ideal for tough size reduction products.

As an exclusive, the Williams Ripshear® Shredder offers an exclusive compact onboard computer that detects a jam through actual shaft stoppage as opposed to the conventional, present pressure limit. With the Williams computer, the Ripshear® Shredder can utilize the full pressure capabilities of its hydraulic components without reversing unless a true mechanical jam develops.

Shafts are fully supported at other end by double row, self-aligning, spherical roller bearings.

Other features of these slow-speed shredders include:

  • Large feed opening
  • Removable hopper section 
  • Oversized bearings and shafts
  • Heavy-duty construction throughout 
  • Optional portability
  • Open bottom permits maximum throughput
  • Product size controlled by disk size and tooth pattern
  • Patented control system including a compact, onboard computer
  • Exclusive side discharge for automatic removal of uncrushables
  • Easily accessible

Electric Ripshear Slow-Speed Shredder

Williams uses a unique bearing design to give the Electric Ripshear® Shredder a significant advantage over other types of slow-speed shredders. The patented Williams Ripshear Shredder design incorporates two bearings vs. the standard, three fixed bearings design. This two-bearing design removes the most destructive stress points, allowing the shafts to flex. The drives are mounted independently and allowed to free-float. This approach makes the Ripshear® slow-speed shredder easy to service and reduces shaft breakage due to fatigue failures.

Another innovation on these unique shear slow-speed shredders is use of an electric soft-start drive which senses the amp inrush and limits the amount of electricity going to each motor, thus limiting torque. This simulates a hydraulic drive without the inefficiencies and increased maintenance normally associated with hydraulic drives.

A patented, quick and simple positive locking system on the rotor stack provides a positive means of securing and preloading the rotor stack while still allowing quick access for maintenance and replacement of cutting teeth.
