Product Overview The Cooked By-Product Roller Crusher is intended for the size reduction of cooked greaves and brittle bone in a dry rendering line. Positioned after cooking and before fat separation, it helps deliver a more consistent feed to downstream equipment. It can be specified as part of a livestock by-product processing project for a commercial pig farm, poultry operation, or centralized rendering facility.
Key Features
  • Two rotating crushing elements break down cooked material and larger bone fragments.
  • Wear-resistant crushing parts support service life under abrasive operating conditions.
  • More consistent greaves size helps prepare material for downstream fat separation and screw pressing.
  • Drive monitoring and blockage protection can be incorporated according to project requirements.
  • Compact equipment layout supports integration with conveyors, cookers, and fat screw presses.
Structural Components Typical components include a feed inlet, enclosed crushing chamber, twin crushing shafts or rollers, wear-resistant crushing elements, drive motor and gearbox, bearings, discharge outlet, and supporting steel frame. Guards, access points, and control interfaces are specified for the selected installation.
Working Principle Cooked by-products enter the crushing chamber from an upstream conveyor or discharge point. Rotating crushing elements draw the material through the working gap, reducing brittle bone and oversized greaves. The processed material exits toward the next fat separation stage. A suitable blockage response should be included in the line controls to protect the drive and downstream equipment.
Technical Specifications
Feed material Cooked animal by-products, greaves, and brittle bone
Installation position After cooking and before fat separation
Throughput and outlet size According to project requirements
Motor power and electrical supply Available upon request
Inlet, outlet, and frame dimensions Customizable to the equipment layout
Applications Dry rendering lines processing cooked pig, poultry, and other permitted animal by-products; cooked greaves preparation ahead of fat screw presses; and rendering facilities associated with large livestock operations. Its role is the reduction of cooked material, rather than whole raw carcass pre-breaking.
Customization Options Feed and discharge interfaces, wear-part selection, electrical controls, drive protection, and frame arrangement can be reviewed against the required throughput and upstream and downstream machinery. For a new pig farm construction project, the installation can be coordinated with the rendering room layout and steel structure building design.
Installation & Maintenance Install the crusher on a suitably designed support, with aligned feed and discharge connections, safe lifting access, electrical isolation, and adequate clearance for inspection. Routine maintenance should include checking crushing elements, bearings, seals, drive components, guards, and blockage controls. Final access and service intervals should follow the approved equipment drawings and operating instructions.
Product FAQ

Where is the crusher installed?
Typically after the cooker and before fat separation or a fat screw press in a dry rendering line.

Can it crush whole raw carcasses?
This configuration is intended for cooked by-products. Whole raw carcasses require a separately selected pre-breaker or raw-material crusher.

Can it replace a metal detector?
No. Although a crusher may retain some large metal objects, foreign-material control should be designed for the complete processing line.
