A. Gupta, Yan, in Mineral Processing Design and Operation, 2006. Roll Crusher Circuit Design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, like chalcocite and chalcopyrite they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing ...

used in underground mining and are still the most common form of rock reinforcement used in Canadian mines. Provided that the rock is hard enough to provide a good grip for the anchor, an expansion shell anchor which is well seated will usually allow a rockbolt to be tensioned to its maximum loadcarrying capacity. In fact, if a bolt is overloaded, it usually fails in the threads at either the ...

Consequently, the major consideration to be addressed in design of underground pipe is not strength but excessive relative movement. Unrestrained slip joints in buried pipe may be subject to relative movement, between the two segments meeting at a joint, that exceeds the limit of the joint''s capacity to function. For that reason, slip joint pipe must be investigated for maximum relative ...
