Some process need only crushing of the material to meet either to requirement of coarse material or to feed smaller sized material to another grinder. Two hardened rolls rotate towards each other. They are kept nearer to each other by means of tether mechanical devices or with hydraulic system helps to create the pressure on the rolls and make the crushing possible. The larger particle of mass, cereals, pulses is pushed between the rolls uniformly spread and with continuous rate through a separate device. A dried feed mass gives material at the bottom with reduced size or if soaked cereals or pulses, give you the material in a flake form
