Maintenance and protection of roller mill;

Set feeding trajectory and infeeding speed as multiple target functions and take horizontal distance and vertical distance between feeding roller and fast roller, rotational speed and diameter of feeding roller and inclined angle between the fast roller and slow roller as design parameters, Particle Swarm algorithms and MATLAB were used in the optimization design of roller mill.

Detailed analysis is made for the feeding non-uniformity phenomena frequently occurred in the feeding system of a break roller mill, and specific settlement methods for them are set forth.
