Four Roller crusher applies to cement, chemical industry, electric industry, metallurgy, construction, refractory material etc. It is usually used in middle and fine crushing stage to crushed medium hardness materials including limestone, coke, coal, gravel, gypsum, ores, mine refuse, furnace slag, steel slag etc. We also has 2pg roll crusher, teeth roll crusher.
Four Roller Crusher Working Principle:
Four Roller Crusher consists of roll wheel, roll bearing, pressing device, adjusting device and driving device etc.etc.It has two kinds of roller surface, one is smooth surface called roll crusher, one is tooth surface called toothed roll crusher.
This kind of Four Roller Crusher machine is consists of two motors, which take two rolls to rotate reversely by the decelerator. When the materials drop on the rolls through the charge hole,under the friction of the rolls, they are dragged between the two rolls, grinded by the roll's crushing, the grinded materials are pushed rotatorily by the rolls.
Pictures of high manganese steel Roll skin (wear parts of four roll stone crushing machine). Huashengming use high manganese steel casting roll skin which is through heat treatment. Because of less quick-wear part which is only roll skin, so four roll stone crushing machine is most popular nowadays.
Four Roller Crusher Advantages:
1. Four Roller Crusher gives a very fine product size distribution and produces very little dust or fines.
2. Four Roller Crusher is effectively used in minerals crushing where the ores are not too abrasive and it is also used in smaller scale production mining of more abrasive metal ores, such as gold.
3. Coal is probably the largest user of roll crusher currently. Coal plants will use roll crushers, either single roller or double roller. Usually, this crusher will have teeth or raised forms on the face of the roll.
4. Besides, Four Roller Crusher is easy to operate, low in consumption, stable in running and simple in fabrication.
5. Four Roll Crusher is stable operation, easy maintenance, low cost, output size adjustable.
