Roller Mills Manufacturers

Roller mill is used in pregrinding or finish grinding of materials. The material between the rolls is submitted to a very high pressure ranging from 100 to 200 MPa. During the grinding process, partial breakdown of the grains occurs and there is a partial formation of incipient cracks in the interior of the grains. The material leaves the press in the form of agglomerates. When the roller press works in the closed circuit for finish grinding, a disintegrator must be used or a special separator must be installed to deglomerate the product. Frequently the roller mill is applied for pregrinding with the ball mill as a second stage. Roller with individual hydropnuematic spring systems provides a very smooth and almost vibration free operation for the mill.
