Bones
Ca₁₀(PO₄)₆(OH)₂ · Animal Bones · Rendered Bones · Bone Meal · Crushed Bone
Bones are dense organic-inorganic composites derived from animal byproducts. They consist mainly of calcium phosphate minerals embedded in a collagen matrix. Depending on processing, bones may be handled as whole pieces, crushed fragments, or ground bone meal. Raw bones can be greasy and odorous, while cooked or dried bones are brittle and abrasive. KWS designs conveying systems capable of handling these heavy, variable, and potentially corrosive materials safely and efficiently.

Common Names
Common Forms
Applications
- Rendering and animal byproduct processing
- Bone meal fertilizer and feed supplement production
- Gelatin and collagen manufacturing
- Pet food and animal nutrition products
Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Whole Bones, Crushed Fragments, Bone Meal Powder |
| Bulk Density | 60–100 lb/ft³ (varies with moisture and processing) |
| Flow Behavior | Free-flowing when crushed or dried; sticky when raw or greasy |
| Abrasiveness | Moderate to High mineral content causes wear on metal surfaces |
| Corrosiveness | Moderate due to organic fats, moisture, and biological activity |
| Dust Potential | Moderate Low for raw bones; moderate to high for dried or ground material |
Handling Challenges
- High abrasion from mineralized bone fragments
- Corrosion from moisture, fats, and biological residues
- Odor and sanitation requirements in processing environments
- Plugging and buildup from sticky or greasy material
- Dust generation and explosion risks in bone meal production
Summary
Bones require conveying and storage systems designed for dense, abrasive, and variable organic materials. KWS Manufacturing provides engineered solutions—including shaftless screw conveyors, drag conveyors, and compactors—constructed from wear- and corrosion-resistant materials to ensure durability and hygiene.
With extensive experience handling animal byproducts and mineralized organic solids, KWS ensures efficient, reliable, and sanitary operation for bone conveying systems.
