Roll Crushers Metallurgist & Mineral Processing Engineer

Mr. Payne’s statement that S. R. Krom was the “pioneer” in introducing into the United States crushing-rolls driven by belts, is, to the best of my knowledge, correct; but Mr. Payne’s statement that S. R. Krom introduced high-speed rolls is not correct. As we understand the term “high-speed” —namely, a peripheral tire-velocity far greater than the falling velocity of the feed

Double Roll Crushers Gujarat, India.

Crushing Rolls: Toothed rings are mounted on the heavy fabricated hub and the rings are kept, in position by holding bolts. These rings are made of wear-resistant steel, like Manganese Steel, or any other hardened steel depending upon the application. Drive: Peripheral speed of rolls is kept between 3m-5m/sec and therefore up to 800 diameter roll crushers are driven, directly by V-belts

Speed of 2 roll mill ProBrewer Discussion Board

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. I'd like to know how do these speeds compare to others. Thanks, Chuck Stuhrenberg Big Muddy Brewing
