Bone Crusher Grinder Machines

A Bone Crusher Grinder Machine is industrial-grade equipment used to crush and grind the large bones of various animals into small particles, powder, or paste. It is commonly used to process beef bones, pig bones, sheep bones, chicken bones, and fish bones. The machine can produce: Crushed bone chips (3–5 mm), Bone powder (100–200 mesh), Bone paste (thick, puree-like texture). These machines are key equipment in industries such as pet food, meat processing, animal feed, gelatin, and biotechnology. We supply three types of bone crushing machines to meet your bone processing needs.

Our Bone Crusher Machine is an industrial device designed to crush animal bones into smaller particles (usually 3–5 mm) for further processing.

Output size: 3–5 mm.
Capacity: Ranging from 20kg/h to 4000kg/h.
Used for:  Pre-processing before fine grinding or boiling.
Function: Crushes large, hard bones into smaller chunks (3–5 mm).
Working Principle: High-speed rotating blades and shearing action.
Main Functions: Crush hard animal bones like cow, pig, goat, sheep, chicken, and fish bones. Produce bone chips or granules. Serve as a preliminary step for bone paste or bone powder production
Industrial Application: Meat processing, Pet food production, Animal feed, Bone meal plants, Pre-treatment for gelatin or collagen extraction.

1. Bone Feeding Hopper
Guides bones into the crushing chamber. Large mouth design for easy feeding.
2. Bone Crushing Chamber
Contains high-strength rotating blades or hammer-type cutters. Made of wear-resistant, food-grade stainless steel.
3. Rotating Shaft / Motor System
Driven by a powerful electric motor. Ensures high-torque crushing force.
4. Discharge Outlet
Crushed bone particles exit from here. Mesh screens may be used to control output size.
5. Frame/Base
Rigid construction to absorb vibration and enhance stability.

The Bone Paste Machine, also known as a bone grinder or colloid mill, is a high-efficiency grinder designed to finely grind crushed animal bones (from a bone crusher) into smooth, uniform bone paste. This paste is used in meat processing, pet food production, bone broth manufacturing, and pharmaceuticals. It is especially suitable for cow bones, pig bones, sheep bones, chicken bones, duck bones, and even fish bones. It works on a wet grinding principle using a colloid mill mechanism, converting crushed bones (3–10 mm) into ultra-fine paste. Enhances bone utilization in food and nutritional products

Capacity: 50-1800kg/h
Output Fineness: 50–200 mesh (adjustable)
Function: Grinds crushed bone into fine powder or paste.
Used For: Making bone paste, pet food, soups, and meat fillings.
Working Principle: High-speed stainless steel rotor and stator grinding.

Meat Processing Industry:

Base Frame – Sturdy SS304 frame with shock absorption

The Bone Shredder and Grinder Machine is a powerful industrial solution designed to crush and grind bones from animals such as cattle, pigs, chickens, and fish into small granules or fine powder through Primary Crushing and Secondary Grinding. This bone shredder and grinder machine is essential in industries such as: pet food manufacturing, bone meal production, and animal feed plants. It can work together with a bone paste grinder to make up a bone processing line. A feed belt conveyor can be added to boost production.

✔️ Heavy-Duty Design: The machine is made of either 201 stainless steel or 304 stainless steel. The robust steel frames and anti-corrosion components for long service life in harsh environments.
✔️ Dual Function – Shredder + Grinder: Combines coarse shredding and fine grinding in one machine to increase efficiency and reduce space needs.
✔️ Customizable Output Size: Equipped with interchangeable screens or sieves to achieve the desired particle size. By changing the different sieve plates, the output size will be 3-10mm.
✔️ Easy Cleaning and Maintenance: Tool-free chamber access and stainless steel parts make cleaning quick and hygienic.
✔️ Safety Systems: Includes emergency stop buttons, overload protection, and interlock switches for safe operation.

Bones Feeding: Raw bones are fed into the hopper manually or through an automatic feeder.
Primary Bone Crushing: A powerful bone shredder section with rotating blades cuts large bones into smaller pieces.
Secondary Bone Grinding: The pre-shredded bones move into the grinding chamber, where high-speed blades or hammers grind them into finer particles.
Bone particle Screening: A screen or sieve controls the final particle size by filtering out oversized material for reprocessing.
Bone Granules Discharge: The processed bone granules are discharged for further processing or packaging.

A convenient and portable bone crushing solution

The diesel engine bone crusher machine, as the name implies, is powered by a diesel engine. This makes it suitable for use in areas where access to electricity is limited or unstable, such as some rural areas, small-scale farms, or mobile processing sites. The main components are a diesel engine and a bone-crushing chamber. This bone crusher machine is mounted on a sturdy frame or base, which provides stability during operation.

Inside the crushing chamber, there are rotating blades or hammers made of high-strength and wear-resistant materials (such as alloy steel). These components are responsible for striking and breaking the bones. The design of the blades/hammers (shape, number, and arrangement) affects the crushing efficiency and the size of the crushed output. It is primarily used to crush various types of bones, including animal bones (such as beef bones and pork bones). It can break large bones into smaller pieces, which is convenient for subsequent processing, such as making bone meal, extracting bone marrow, or further processing in the food, feed, or fertilizer industries.

Heavy-duty Construction: Handles tough animal bones (cow, pig, goat, etc.)
Food-grade SS304: Corrosion-resistant and hygienic
Adjustable Output Size: Multiple applications from coarse chips to fine paste
Multifunctional: To handle different types of animal bones.
High Capacity: Efficient for both small and industrial-scale production
Easy to Clean & Maintain: Sanitary design with quick-disassemble parts

Meat Industry: Preparation of bone broth, sausage filling, and bone-in meat paste.
Pet Food Industry: Production of bone meal and bone paste for pet nutrition.
Feed Industry: Bone meal as a calcium and phosphorus supplement for livestock and poultry.
Pharmaceuticals: Extraction of gelatin and collagen for capsules and health supplements.
Fertilizer Industry: Some organic fertilizers are made from bone meal.
