Description

To cater for this industry, Pin mills are used to pulverize medium to somewhat hard materials with a maximum hardness of up to 3 Mohs. A wide range of different machine sizes is available. Pin Mills are type of Disc Grinders, also known as Centrifugal Impact Mills (CIMs). Pin mills are a type of high-speed-impact mills consisting of a feed inlet, a set of two disks with concentric rings of pins and a product outlet. Particle size of as low as 2 µm can be achieved with the use of finest quality Pin Mills. Pin mills are capable of very fine grinding without the need for screens and provide a uniform powder size.

Principle

Pin mill employs shearing and impact forces to produce fine particles. The grinding action within the Pin Mill is achieved by impacting the product particles with a series of hardened steel pins. The product enters through the eye of the machine and then passes through rows of pins rotating at high speed between stationary pins. The product particles are shattered into fragments as they progress towards the outlet, progressive becoming smaller in size as they approach the periphery (this is because the distance between the pins decreases as we move radially outwards).
