Example If a bottom roll had an original throat diameter of 4.500quot, and was reworked to 4.250quot, you would subtract the smaller diameter from the larger diameter, where in this case would be .250quot. You would then divide .250quot by two 2, which would be a .125quot thick shim to be placed under the bottom bearing block of this reworked pass.Online Consulting
Msec with roll speed differentials. Roll speed differentials simply means one roll turning faster than the other and is usually described in the form of a ratio, slow roll speed expressed as 1. For example, rolls operating at 1.51 differential with a fast roll speed of 1,000 RPM would have the slow rollOnline Consulting

Speed of 2 roll mill 04192009, 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.Online Consulting
