3. Finely crushing all kinds of ore and rock below the high, medium hardness,which can make the minimum grain size below 100 mesh.

4. Stable operation, easy maintenance, low cost and output size adjustable.

Applications

Roll crusher applies to crushing medium hardness materials such as coke, sinter, limestone,various metal ore and nonmetal ore.It is most suitable for medium and fine crushing in small and medium-sized nonmetal mines and chemical industry.The minimum size can reach 100 mesh.

Working principle:

The motor drives the fixed roller and movable roller to work via reducer, V-belts or coupling. Materials are put into the space between the two rollers via the feed entrance, as the two rollers inward turning, the input materials are crushed, pressed, ground, and at last come out from the base of the machine.When there are unbreakable materials or the material is too hard, the roller will concede automatically under the effects of spring and hydraulic pressure, which will widen the clearance between the rollers and make the hard or unbreakable so as to avoid damaging the machine. The clearance between the two rollers can be adjusted to change the sizes of final products.
