Kaolin, a soft mineral with a Mohs hardness of 2.0-3.5, requires a comminution process that balances production capacity and particle size requirements. For a production capacity of 5 tons/hour, a hammer mill, with its simple structure and adaptability, is the preferred equipment. The following are key selection recommendations:

Recommended Model: Core Parameters

SCF600×400 Hammer Mill

Capacity: 5-6 tons/hour

Feed Particle Size: ≤200mm

Discharge Particle Size: 0.5-2mm (Adjustable)

Applications: Primary to secondary crushing of kaolin. A ball mill can be used to form a complete grinding production line.

Processing Capacity

A twin-rotor hammer mill is recommended, capable of processing 5-8 tons/hour (at a moisture content ≤15%). The discharge particle size can be controlled within the 0.5-2mm range by adjusting the hammer speed (800-1200 rpm).

Wear-Resistant Design Optimization

Kaolin containing quartz impurities is prone to wear. Therefore, equipment equipped with a high-chromium alloy hammer (hardness HRC ≥ 60) and a shiftable gap adjustment mechanism can extend service life to over 3,000 hours.
