Bentonite Grinding Mill: Key Features and Selection Guide for Efficient Powder Processing
Introduction to Bentonite Processing
Bentonite, a highly absorbent aluminum phyllosilicate clay, requires specialized grinding equipment to achieve optimal particle size distribution for industrial applications. As a leading manufacturer with over 30 years’ experience in mineral processing, ZENITH understands the technical challenges in bentonite milling – from moisture control to maintaining montmorillonite structure integrity during size reduction.
Critical Parameters in Bentonite Grinding
- Moisture Sensitivity: Requires <3% residual moisture for efficient grinding
- Particle Shape: Platelet structure demands shear-dominant milling
- Thermal Limits: Max 70°C to prevent crystal structure damage
- Output Range: 200-2500 mesh for drilling/chemical/feed applications
