sand making machine, the company is using \"stone stone\" theory and technology, combined with sand production, the actual situation, developed a domestic and international, the leading high-level gravel equipment. It is widely used in a variety of rock, abrasive, refractory materials, cement clinker, quartz, iron ore, concrete aggregate and other hard, brittle materials in the debris, fine For construction sand, gravel roads with excellent as appropriate. Material from the machine into the upper part of the vertical high-speed rotation of the impeller, centrifugal force at high speed, with another part of the Umbrella in the form of streaming high-speed impeller produces the material around the impact and crushing, the material impact on each other, then they will in the impeller and to form a vortex between the chassis number of each material impact, friction and grinding, through discharge from the lower part of the formation of many closed loop
