The roller press is a new type energy saving cement grinding equipment developed in the mid 1980s. It can completely or partially replace the ball mill that is highly energy consuming. In addition, featuring the functions of low material consumption and low noise, this roll squeezer is an ideal choice for both new factory construction and old plants technical transformation.
   After equipped with this grinding equipment, the ball mill system can achieve 40-100% improvement of output. In the squeezed materials, the ingredients with 0.08mm fineness occupy 20-55% and those with the fineness less than 2mm occupy 65-85%. Since the internal structure of the small grained materials is filled with a large number of tiny cracks resulted from press, they are much easier to be ground.
