The roller crusher is used to crush small and medium pieces of clay, shale, coal gangue and other raw materials by brick and tile enterprises. The two working rollers of rusher rotate in reverse direction, and the clay and other raw materials between rollers are squeezed and broken. The distance between rollers can be adjusted according to the required crushing size and crushing ratio of feeding / discharging. The coarse crushing has two compressedadjusting springfor roller crusher, which can avoid the entrance of too large or hard materials to damage rolling circle and equipment.
