Each set is made up of the rack, toothed roller, transmission device, adjustment device for the toothed roller clearance, and other working parts.

2. Features

l With the reasonable design and compact structure, the equipment possesses the characteristics such as big crushing ratio of combination, uniform grain size of discharge, small power consumption and large production capacity etc.

l It has no requirement on the water content of the crushing materials without gluing and pl ing.

l Due to the merits of small repeated crushing, low noise, small vibration, less dust, small floor area, and simple and convenient maintenance

l It is the preferred crushing equipment with energy saving, environmental protection and efficient.
