Slippage occurs in all crushers even in ideal conditions Only the particle’s weight and the friction between it and the crusher surfaces counteract this tendency In particular very hard rock tends to slip upward rather than break Choke feeding this kind of material can overload the motor leaving no option but to regulate the feedMar 07 32 I read with interest a thread now closed that dates back to July on a similar subject I am trying to evaluate the internal angle of friction of crushed limestone as a backfill material max particle size of 25mm

Oct 05 32 Calculating rolling force To help quantify rolling resistance in industrial wheels there is the “coefficient of rolling friction” This is a number that has been empirically determined for different materials and can vary by the speed of the wheel the load Roll Crushers are compression type crushers and were once widely used in mining They have within the last 10 or so years fallen into dis favor among mining and processing compani The probable reason is because the large mines require very large crushed product output with minimal cost makes the roll crusher uncompetitive
