Working principle:
Centrifugal impact pin mill is a compact, high speed impact mill capable of fine size reduction specially designed for chemical and food application.
Material is fed into the grinding chamber via the central inlet of the opposing stationary disc by gravity or screw feeder. High speed rotation of the inner disc creates centrifugal force that accelerates bulk material moving from the center to the periphery of the discs at high speed. As materials pass through a path of intermeshing rows of rotating and stationary pins, grinding is done by strong impact and shearing between the pins. The centrifugal force or air stream generated by draft fan force the product go through a filtering sieve which is around the grinding chamber to get required particle size. Different particle size is determined by the speed, number, type of pins and hole size on the sieve.
Centrifugal impact pin mill has been commonly used for coarse to fine grinding of soft to medium hard, brittle and crystalline materials in food and chemical industry.
Product technologies:
Fineness range from 60 mesh to 200 mesh
Fineness can be adjusted by the rotor speed and grinding tool selection
Relative linear speed up to 150m / sec
Can handle the different materials of Mohs hardness 2-3.5
Easy to operate, easy to clean
The scope of application from the laboratory model to large-scale production models.
