Product Overview The Whole Carcass Pre-Breaker performs the first stage of size reduction in an animal by-product processing line. It breaks down pig and other livestock carcasses, bones and offal into pieces that can be transferred to downstream crushing or rendering equipment. For commercial pig farm projects, it can form part of a dedicated carcass handling and treatment area designed around the farm's collection method and processing capacity.
Key Features
  • Heavy-duty construction for demanding carcass and bone handling.
  • Low-speed, high-torque breaking action suited to coarse size reduction.
  • Accessible wear components to support inspection and replacement.
  • Inlet, outlet and drive arrangement adaptable to the processing line.
  • Can be integrated with receiving bins, conveyors, secondary crushers and rendering units.
Structural Components The typical assembly includes a feed inlet, reinforced breaking chamber, breaker shaft and knives, opposing breaking surface, drive motor, gearbox, bearings, discharge opening and support frame. Guards, access points and control interfaces are specified according to the selected configuration.
Working Principle Carcasses or animal by-products enter the breaking chamber through the feed inlet. Rotating knives draw the material into the chamber and break it against the opposing surface. The reduced material exits through the discharge opening for conveying, further crushing or subsequent rendering. The pre-breaker is intended for coarse preparation; the required final particle size determines whether another crushing stage is needed.

Applications Suitable for the initial preparation stage of livestock mortality treatment facilities, slaughterhouse by-product lines and animal rendering plants. In pig farm construction projects, the machine can be incorporated into a separate processing building or a purpose-designed area within a steel structure building, subject to the site's hygiene and operating requirements.
Customization Options Feed opening, shaft arrangement, drive selection, discharge connection, support frame and line integration can be designed according to the carcass mix, daily processing volume, available space and local climate and farm conditions. Confirm the intended downstream process before selecting the machine configuration.
Installation & Maintenance Install the unit on an engineered foundation or support structure with access for feeding, discharge, cleaning and service. Coordinate inlet and outlet heights with adjacent equipment during layout design. Routine maintenance includes checking knives and other wear surfaces, bearings, lubrication points, drive components, fasteners and protective devices. Isolate power before inspection or cleaning.
Product FAQ

Can the machine process whole pig carcasses?
Yes, when the inlet, shaft and drive are specified for the carcass size and expected feed rate.

Does a pre-breaker replace a fine crusher?
It performs coarse size reduction. A downstream crusher may be required when the rendering process calls for smaller pieces.

What information is needed for selection?
Provide the animal types, maximum carcass dimensions, expected throughput, target discharge size, power supply and processing-line layout.
