COMPARISON OF ENERGY EFFICIENCY BETWEEN A ROLLER MILL

COMPARISON OF ENERGY EFFICIENCY BETWEEN A ROLLER MILL

For roller mill grinding, roll gap was the most significant factor affecting energy requirement, followed by the roll speed differential. For hammer mill grinding, screen opening size had the most significant effect. For both mills, feed rate was not significant and energy efficiencies were about the same.

Speed of 2 roll mill 04-19-2009, 0706 AM. We purchased a used 2 roll mill and was wondering about the RPM speed of the rolls. They are about 7 in. diameter and are turning at about 180 rpm. This seems fast to me. I feel we would get a better crush if they turned slower. Id like to know how do these speeds compare to others.
