The bone grinder is capable of processing materials sized from 5 to 80 mm, including cattle bones, poultry bones, and various shells. With a wide capacity range of 20–2200 kg/h, the Bone Grinder can be configured for both small-scale applications and large industrial production lines.
Powered by a high-torque variable frequency motor and a multi-stage spiral blade system, the machine delivers stable crushing performance, flexible speed control, and uniform output while effectively reducing the risk of clogging.
It offers a reliable solution for crushing hard materials in food processing, biopharmaceutical, and agricultural industries, combining high grinding efficiency with industrial-grade durability to support continuous operation.
The consistent particle size of the finished material makes it suitable for downstream processes such as fine milling, extraction, or further formulation. With robust construction, flexible capacity options, and stable performance, the Bone Grinder is a practical and efficient choice for hard-material crushing operations.
Bone crushing machine applications
The bone crusher is a versatile industrial equipment designed to process animal bones (pig, cattle, chicken, sheep, fish bones) and diverse materials including meat, traditional Chinese herbs, spices, and more. Its adaptability makes it indispensable across multiple industries.
- Food processing. Widely used in sausage factories, ham plants, meatball production lines, and seafood facilities to create bone meal additives or enhance meat texture.
- Pharmaceuticals & herbal processing. Efficiently grinds dried herbs and medicinal ingredients for formulations.
- Seasoning production. Crushes spices and seasoning blends for uniform particle distribution.
In practical applications, the machine’s multi-fineness adjustment (5-80mm) and high-capacity output (up to 2,200kg/h) ensure seamless integration into large-scale operations.
For instance, a Canadian meat processing plant adopted this system in July to optimize bone utilization and reduce waste, demonstrating its global reliability and industrial efficiency.
Bone grinder machine structure
- Raw material inlet – Feeds bones into the crushing chamber.
- Crushing chamber – Houses high-speed rotating blades for shredding.
- Cutter system – Multi-layered blades designed for continuous cutting.
- Regulating system – Adjusts clearance between stator and rotor to control fineness.
- Transmission system – Transfers power from the motor to the cutter.
- High-torque motor – Drives blade rotation at optimized speed.
- Outlet – Discharges uniformly crushed bone particles.
How does the industrial bone grinding machine work?
- Feeding – Bones enter through the inlet into the crushing chamber.
- High-speed shredding – Blades rotate at ultra-high speed, shredding bones through continuous cutting and shearing forces.
- Precision grading – Fineness is controlled by adjusting the stator-rotor clearance, offering three preset levels: coarse, medium, and fine.
- Output – Crushed bone particles are discharged via the outlet, ready for further processing.
Bone grinder features
- High-durability blades – High-carbon steel with special alloy heat treatment, reusable through multiple sharpenings, evenly distributed force for enhanced cutting efficiency and extended lifespan.
- Three-level fineness adjustment – Coarse, fine, and ultra-fine grinding, flexibly controlled by the stator-rotor gap (adjustable from 5-80mm) for uniform particle size.
- Safety design – Food-grade contact materials, sound-insulated feeding hopper, motor overload protection, and a safety control system ensure safe and low-noise operation.
- High-efficiency automation – Integrated cutting, grading, and discharge process, supporting high-capacity output of 20-2200kg/h with stable, low-temperature operation.
- Easy maintenance structure – Modular design with one-touch self-cleaning, corrosion-resistant 316L stainless steel body for easy maintenance.
- Energy-saving & eco-friendly – 30% energy-saving power design, pollution-free processing, and compliance with national food safety standards.

Why a bone grinder is essential for grinding bones?
Ordinary fresh or frozen meat grinders are not suitable for grinding bones. Meat grinders are designed specifically for soft materials, with blade structures and strength matched to meat characteristics. Bones are significantly harder and tougher, and attempting to process them with a standard meat grinder can result in poor crushing performance and serious blade damage.
A specialized bone grinder is essential because it is built to handle the high hardness of bones. With reinforced blades, stronger drive systems, and optimized crushing structures, a bone grinder can efficiently process bones without damaging the machine.
In addition, bone grinders are capable of processing meat as well, making them a more durable and versatile solution for applications that involve both meat and bone materials.
How to maintain and clean a bone crusher machine?
- Disassemble the machine. Carefully take apart the bone grinder, paying close attention to each component, including the blades, grinding plates, and hopper.
- Soak the parts. Use a mild detergent solution and warm water to soak these parts, helping to remove any residue of bone fragments or grease buildup.
- Clean with a brush. Use a small brush or toothbrush to clean intricate areas, ensuring that all parts are thoroughly cleaned.
- Rinse and dry. Rinse all parts thoroughly with clean water and allow them to air dry completely before reassembling the bone grinder.
- Reassemble the machine. Put the bone grinder back together, ensuring that all components are properly secured.
- Regular cleaning. Clean the bone crusher machine regularly after each use to prevent bacterial growth and extend its lifespan, ensuring optimal performance for processing bones and other materials.
