Grinding •Grinding: the mechanical process of reducing particle size of solids, while the specific surface area increases parallel with the reduction of the particle size. It is commonly done by mills. •Crushing: the division of the original particle into some rough particles (work in the 'mm'-range) •Milling: the division of the rough particles and gain fine

A hammer mill is equipped with a simple rotating disc equipped with many pallets that are hitting the product and throwing it against the mill housing. A grinding sieve that will allow to enhance the milling process and reduce the Particle Size Distribution obtained can also be installed. High speed hammer mills (tip speed from 40 to 70 m/s ...

The industrial pin mill (also known as a universal mill, turbo mill, and impact mill) is a one pass grinding equipment ideal for achieving the micronization of bulk materials and powdered products. Common applications involve the fine grinding of sugar, salt, sodium bicarb, etc. The average achievable particle size range of the pin mill is around a d50 of 80 microns.

By contrast, attrition milling relies on a horizontal rotating vessel filled with a size-reduction solution. Treated to grinding media, the materials tend to be turned into free-flowing, spherical particles. This method, which includes the ball mill, can reduce 1,000 micron (20-mesh) particles of friable materials down to less than 1 micron.
