Milling and Grinding Technology

Lakeshore uses an Air Classifier Milling System. This type of mill operates on the principle of impact grinding and employs high rotor speeds with a striking edge velocity of up to 120 m/s. Size reduction takes place by the impact of material particles on the rotating grinding surfaces (hammers or pins) and on the fixed liner, or grinding track. Designed with an integral classifier, particle size, distribution and cut point can be accurately controlled by variable classifier speed. The benefits of this system include:

  • Grinding and classifying in one machine

  • Ability to attain medium to fine size reduction

  • A cool grinding process with high air to product ratio

  • Steep particle size distribution

  • Sharp classifier cut point, instantly adjustable
