The bone crusher machine is a professional crushing equipment designed for processing various animal bones such as beef bones, pork bones, chicken bones, fish bones, and sheep bones. It is widely used in meat processing plants, pet food factories, bone meal production lines, and food ingredient industries.
This machine can crush fresh bones, frozen bones, and dry bones into granules of different sizes (typically 3–50 mm), making it an ideal pre-processing equipment before fine grinding or colloid milling.
With a capacity range from 20 kg/h to 4000 kg/h, the bone crusher can meet both small-scale and industrial production needs.


Applications
The bone crusher machine is widely used in:
Food Industry
- Sausage production
- Meatball processing
- Bone broth and soup base
Pet Food Industry
- Bone paste
- Pet snacks
Feed Industry
- Bone meal production
- Animal nutrition supplements
Further Processing Line
- Combined with colloid mill → bone paste
- Combined with grinder → bone powder
Animal bones contain rich protein, calcium, and minerals, making them highly valuable raw materials in the food and feed industries.


Principe de fonctionnement
The bone crusher machine adopts a high-speed rotating knife system. The motor drives the rotor to rotate rapidly, and the bones entering the crushing chamber are subjected to:
- Shearing force
- Impact force
- Cutting force
- Grinding force
Through continuous crushing by multiple blades, the bones are broken into uniform particles.
The particle size can be adjusted by changing the screen mesh, ensuring flexibility for different downstream processes.


Machine Structure
The industrial bone crusher mainly consists of:
- Feeding hopper (large inlet design for easy feeding)
- Crushing chamber (equipped with rotating blades)
- Knife system (fixed + movable knives)
- Motor & transmission system
- Discharge outlet with screen
High-quality alloy steel blades ensure strong impact resistance and long service life.
