Meat and Bone Crusher PPM-7 with Stainless Steel Screw Conveyor

PPM-7 is an industrial meat and bone crusher designed for the pre-grinding of large bones, heads, and other slaughter by-products into particles up to 30 mm.

The machine is widely used in the feed, fertilizer, and processing industries, as well as on farms and in rendering plants.

Thanks to its robust construction and powerful motor, the PPM-7 handles hard materials efficiently, making it a reliable solution for companies processing animal-based raw materials.

Operating principle:

Raw materials are fed into the working chamber through a 400 × 300 mm loading opening, where rotating gear wheels crush the material. The processed material can then be transported by a screw conveyor (2.2 kW / 1500 rpm) to the next stage, such as a PM-18 crusher or storage.

Applications:

• Production of bone meal and meat-and-bone meal
• Feed and fertilizer manufacturing
• Alternative fuel processing
• Animal farms, processing plants, zoos, zoological parks

Key advantages:

• Efficient grinding of hard and bulky elements to ≤30 mm
• Reliable 7.5 kW motor (1500 rpm) ensures high output and durability
• Optional 2.2 kW auger (1500 rpm) enables smooth and continuous material transport
• Durable construction suitable for heavy-duty industrial use
• Integration capability with other machines in processing lines

Technical specifications:

• Output capacity: depends on the type and structure of material
• Final particle size: up to 30 mm
• Main motor: 7.5 kW, 1500 rpm
• Screw motor (optional): 2.2 kW, 1500 rpm
• Weight (without auger): 500 kg
• Inlet dimensions: 400 × 300 mm

The PPM-7 is a proven and effective solution for businesses seeking a reliable machine for pre-grinding meat and bone waste in preparation for further processing into feed, fertilizers, or biomass. Choose the configuration that best suits your production needs – with a hopper or screw conveyor.
