crushing plant roll grinding machine for rock ,coal,limestone,stone crushing
Product Description
Four Roll Crusher Application:
Four Roll 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 Roll Crusher Working Principle:
Four Roll Crusher consists of roll wheel, roll bearing, pressing device, adjusting device and driving device etc.etc.It has two kinds of roll surface, one is smooth surface called roll crusher, one is tooth surface called toothed roll crusher.
This kind of Four Roll 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 Roll Crusher Advantages:
1. Four Roll Crusher gives a very fine product size distribution and produces very little dust or fines.
2. Four Roll 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 Roll 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.
The entire center feeding: Sand Making Machine Material falls the feed hopper, then enters the high-speed rotary sling wheel from center feeding hole, which is speeded immediately in the sling wheel. crushing plant roll grinding machine for rock ,coal,limestone,stone crushing The speed can reach several dozens times of the gravity acceleration. Then Sand making machine is thrown from the sling wheel. First, Sand Making Machine is crushed with other rebounded material fell freely from the sling wheel.

Then both of them are impacted to the material lining (rock-rock) or strike back block (rock-iron), rebounded and stroke to the Good of eddy cavity of Sand making machine in the inclined-up direction. Then crushing plant roll grinding machine for rock ,coal,limestone,stone crushing moves along deflection-down, and forms a continuous material curtain with the material from the impellers passage. Just like this, the material is stroke, rubbed, crushed twice or more, then is discharged from the down discharging hole. There is little loss for medium-sized and fine sand and stone powder. Sand Making Machine The grade and the fineness of the sand for construction after being washed can be up to the national standards, such as sand for construction and cobble and broken stones for construction. There are no other wear parts except the screen mesh. crushing plant roll grinding machine for rock ,coal,limestone,stone crushing has longer service life and little maintenance chance.
