Jiangsu Pengfei Group Co., Ltd. has established a large roller press production base with an annual output of more than 200 sets of various roller presses and high-pressure roller mills, which are widely used in cement, metallurgy, mining and other industries. The system applies the principle of high-pressure material layer grinding and adopts the working mode of unit crushing and group grinding. After high-pressure extrusion, the particle size of brittle materials decreases. The content of fine powder less than 0.08mm reaches 20-30%, and that of materials less than 2mm reaches more than 70%. There are a lot of cracks in all extruded materials. When the materials enter the next grinding process, the energy consumption is greatly reduced and grinding is carried out The system can increase production by 50-100% and reduce unit wear by 30-50%. All grinding systems, including roller press, disintegrator, ball mill, powder concentrator, are suitable for new plant construction and old plant reconstruction. It has the characteristics of high automation, low investment, reasonable process layout, small land occupation, convenient layout, low operation cost, convenient maintenance, etc.
