From crushing of raw material to grinding and packing, it is an independent production system. 2.The grinding device of the main unit is fixed with 1000 1500 kg pressure springs. When the machine works, the grinding roller which under the action of high pressure spring and centrifugal force, rollers close up to grinding ring.
