  • Roll Crusher an overview ScienceDirect Topics

    Roll crusher operation is fairly straightforward: the standard spring rolls consist of two horizontal cylinders that revolve toward each other (Figure 6.14(a)). The gap (closest distance between the rolls) is determined by shims which cause the spring-loaded roll to be held back from the fixed roll.

    24-04-2015· The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls. Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines. Rolls crushers

  • Factors to Consider When Selecting the Proper Roll Crusher

    When selecting the proper Roll Crusher for an application, you must fully consider all the components of the crushing process. There are numerous factors to be considered, such as: The material to be crushed; Feed size; Product size; Ratio of reduction; Capacity; Compressive strength; Moisture content; Amount and type of refuse present in the feed

  • Roll Crusher an overview ScienceDirect Topics

    Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as 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 is employed.
