This machine adopts two alternating-current motors to respectively drive toothed rollers at both sides of the coarse and fine crush throug the power veee belt, to make the coarse and fine crush toothed rollers rotate toward each other.After entering the crushing cavity through the feeding hole, the materials are crushed by various combinations of splitting, breaking and striking of two-coarse toothed rollers with high speed revolution.The grain size reaches about 40mm after the coarse crush. They directly falls into the fine crushing cavity wiht the same crush, and then are crushed into the satisfactory grain size.The grain size can be finished through adjusting the clearance of the coarse and fine toothed rollers.With the reasonable design and compact structure, the equipment possesses the characteristics such as big crushing materials without gluing and plugging.Due to the merits of small repeated crushing, Low noise, small vibration, less dust,small floor area, and simple and vonvenient maintenance, it is the preferred crushing equipment with energy saving, environment protection and feeicient.
