Bentonite clay, a versatile industrial mineral, requires specialized grinding equipment to achieve optimal particle size distribution for applications in foundry, drilling fluids, and construction materials. This article evaluates five high-capacity grinding mill technologies capable of processing bentonite at industrial scales, with detailed performance comparisons and equipment recommendations.
Vertical roller mills employ multiple grinding rollers that rotate against a stationary grinding table. The LM Series Vertical Roller Mill exemplifies this technology with its integrated grinding-drying-classification system.
| Model | Grinding Capacity (t/h) | Power Consumption (kWh/t) | Fineness (μm) |
|---|---|---|---|
| LM190K | 23-68 | 18-22 | 45-170 |
| LM220K | 36-105 | 16-20 | 45-170 |
For applications requiring sub-10μm particle sizes, our SCM Ultrafine Mill series delivers exceptional performance with D97≤5μm capability. The patented three-ring medium-speed micro-grinding mechanism achieves:
| Model | Capacity (t/h) | Motor Power (kW) | Fineness Range (mesh) |
|---|---|---|---|
| SCM800 | 0.5-4.5 | 75 | 325-2500 |
| SCM1680 | 5.0-25 | 315 | 325-2500 |
The MTW Series Trapezium Mill features innovative curved air duct technology that reduces turbulent flow losses by 15-20%. Its bentonite processing capabilities include:
Our MRN Pendulum Mill series incorporates a patented multi-stage classifier that achieves:
For operations requiring simple maintenance and proven technology, our GMQG Series Ball Mills provide:
| Application | Recommended Mill Type | Typical Capacity | Energy Efficiency |
|---|---|---|---|
| Foundry Grade (200 mesh) | MTW Trapezium Mill | 15-45 t/h | 22-25 kWh/t |
| Drilling Mud (325 mesh) | SCM Ultrafine Mill | 5-25 t/h | 35-40 kWh/t |
| High-Purity (2500 mesh) | LUM Ultrafine Mill | 1.6-15 t/h | 55-65 kWh/t |
For bentonite processors requiring both high capacity and fine particle control, our SCM Ultrafine Mill and MTW Trapezium Mill offer the most advanced technological solutions. The SCM series particularly excels in pharmaceutical and cosmetic grade applications with its ability to produce 5μm particles at 25 t/h capacity, while the MTW series provides robust performance for bulk industrial applications. Both systems feature our proprietary intelligent control systems that automatically adjust operational parameters for optimal grinding efficiency.
