MTM Medium Speed Trapezium Mill: A Game-Changer for Animal Feed Additive Manufacturing
In the rapidly evolving animal husbandry industry, high-quality limestone powder has emerged as a critical component for optimizing livestock health and productivity. As a leading manufacturer of advanced grinding equipment, SBM leverages its cutting-edge MTM Medium Speed Trapezium Mill to produce ultra-fine limestone powder that meets the stringent requirements of modern feed additives. This article explores how MTM grinding technology addresses key challenges in animal nutrition while delivering unmatched efficiency and sustainability.
Why Limestone Powder Matters in Animal Feed
Limestone (calcium carbonate) serves as the primary calcium source in animal feed formulations, directly impacting:
- Skeletal Development: Essential for bone strength in poultry, swine, and cattle
- Metabolic Functions: Regulates enzyme activity and nutrient absorption
- Disease Prevention: Reduces risks of rickets, osteoporosis, and eggshell defects
To maximize these benefits, feed-grade limestone must achieve:
- Particle Size: 45-325 mesh (0.038-0.3mm)
- Purity: >95% CaCO3 content
- Uniformity: D97 distribution within ±5μm
Technical Superiority of MTM Mill in Feed Additive Production
1. Precision Grinding for Optimal Particle Distribution
The MTM series achieves 45-325 mesh output (adjustable to 0.038mm) through its innovative grinding mechanism:
- Multi-Layer Grinding Rings: 4-6 vertically stacked grinding zones ensure progressive size reduction
- Spring-Loaded Rollers: Automatic pressure adjustment compensates for wear, maintaining consistent fineness
- Dynamic Classifier: Integrated centrifugal separator removes oversize particles (D97≤5μm control)
2. Enhanced Production Efficiency
With 3-22 TPH capacity across models, MTM mills outperform traditional ball mills in limestone processing:

3. Advanced Contamination Control
MTM’s closed-loop design ensures feed safety compliance:
- Pulse Dust Collector: 99.9% filtration efficiency, emissions <20mg/m³
- Food-Grade Lubrication: Isolated oil circuit prevents material contamination
- Wear-Resistant Components: High-chrome alloy rollers extend service life to 8,000+ hours
4. Smart Automation for Consistent Quality
Key features supporting automated feed additive production:
- PLC-controlled grinding pressure and classifier speed
- Real-time particle size monitoring via laser analyzers
- Remote diagnostics and performance optimization
