The roller mill process uses the stress exerted by the rotating wheel and the grinding process. When grinding the solid and some solid materials in the suspension paste or ointment, the roller rotates at different speeds. When the material passes through the gap, it is sheared to obtain the required particle size, as follows: constrained
