The core working principle of the bone crusher is to crush bones into bone chunks, bone particles or bone powder through shearing, impact, extrusion and grinding force generated by high-speed rotating cutters, hammers or twin rollers.
1. Main Types & Working Principles
Shear Type Bone Crusher (Primary Crushing)
Structure: Motor, cutter shaft, fixed cutter & rotary cutter group, crushing chamber, screen mesh. Working process:
- Bones fall into the crushing chamber from the feeding hopper.
- The high-speed rotating cutters cooperate with fixed cutters to generate strong shearing and splitting force to break large fresh bones or frozen bones.
- Crushed materials pass through the screen mesh and discharge up to the required size.Application: Coarse crushing of large bones into medium pieces.
Hammer Mill Type Bone Crusher (Medium Fine Crushing)
Structure: Main shaft, movable hammer pieces, toothed lining plates, screen mesh. Working process:
- Materials are impacted and beaten repeatedly by high-speed swinging hammers.
- Further crushed by collision and friction between materials and inner wall plates.
- Qualified fine materials are screened and discharged.Application: General medium and fine bone crushing with high efficiency.
Grinding Type Bone Mill (Ultra-fine Processing)
Structure: Rotor & stator, multi-stage tooth rings, adjustable gap structure. Working process:
- Bones are squeezed, sheared and finely ground in narrow gaps.
- Gradual fine processing from coarse to ultra-fine by adjusting the gap.Application: Make bone paste, bone mud and superfine bone powder.
Twin Shaft Shredder (Heavy-Duty)
Structure: Two counter-rotating shafts, interlaced cutter discs. Working process: Realize powerful tearing, biting and extrusion through meshing cutters. Application: Large-scale slaughterhouse bone processing and whole bone shredding.
2. General Working Flow
- Feeding: Manual feeding or conveyor automatic feeding
- Crushing: Complete shearing, impact and grinding
- Grading: Control particle size by screen mesh
- Discharging: Output finished bone chunks, particles or powder
- Power Drive: Motor and reduction transmission system
3. Key Equipment Features
- Wear-resistant alloy cutter and hammer for high hardness and impact resistance
- Adjustable crushing gap to control finished fineness
- Food-grade stainless steel body, corrosion resistance and easy cleaning
