Grinding Mills - Blogger

Grinding can be done by several mechanisms, including impact or compression, due to forces applied almost normally to the particle surface; chipping due to oblique forces; and abrasion due to forces acting parallel to the surfaces. These mechanisms distort the particles and change their shape beyond certain limits determined by their degree of ...
