Product Information
Roll crusher to pay attention to the following:
1)To strengthen the work to the removal of iron ore. Non-broken material (solder first class materials) fall into the room on roller crusher damage, resulting in parking accident. So breakers should be installed before the addition of iron device.
2)Viscous material easy to plug the break room, plug in the treatment failure should stop processing, not to poke mine in operation.
3)When dealing with large more materials, we should note that large ore easily squeezed out from the break room, to prevent injury, or damage equipment.
4)Roll crusher run a long time, due to the roll surface wear larger size too small will lead to products, then adjust the arrangement to pay attention to mine mouth or on equipment maintenance.
5)Strengthen the inspection of equipment, lubrication equipment parts on time and fuel to maintain good lubrication equipment.
Roll crushers' structure and working principle:
Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension.
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 are effectively used in minerals crushing where the ores are not too abrasive and they are also used in smaller scale production mining of more abrasive metal ores, such as gold. Coal is probably the largest user of roll crushers, currently, though. Coal plants will use roll crushers, either single roll or double roll, as primary crushers, reducing the ROM coal. Usually, these crushers will have teeth or raised forms on the face of the roll. (Roll crushers used for minerals and metal ores have smooth faced rolls.)
