Pin mills are used to reduce the size of medium- to low-density materials such as talc and clay. Pin mills use centrifugal forces to smash large particles against pins. Equipment Design A colloid mill rotor is an intermeshing rotor used for the size reduction of materials by multiple impacts with the maze of pins.
High-speed stirred mills are utilized to grind particles below 10mm. Grinding sulphide minerals to as low as 10mm achieve adequate mineral liberation for successful downstream mineral processing operations, such as flotation and leaching. Particle breakage mechanism such as fracture or abrasion, determines the morphological surface features of the product particles.
