Milling is the unitarian operation that enables to reduce particle size of dry solids or dispersed in a liquid vehicle.
In the milling of dry solids, the physical process is based in the impact of the particles against a moving element of the mill. We can distinguish four types of basic equipment for this kind of milling technology:
- Ball mill: it is a cylinder located in horizontal position that turns on its axis. Inside the cylinder the balls impact against the solid reducing its particle size (Figure 1).
- Impact mill: there are several milling elements (pins, beaters, hammers) that spin at high-speed allowing particle size reduction. The choice between the different elements depends on the nature of the product, its initial particle size, and the required final particle size.
