Suitable for mining, construction, chemical, electric power, metallurgy and other industries, broken compressive mild not more than 250 MPa of ore and limestone, slag, coke, coal and other, the machine should not be with the surface water more than 8-10% of the ore or viscous material crushing. Its performance has reached the international advanced level, is the most effective, practical and reliable gravel machine, and is especially suitable for manufacturing abrasive, refractory material, cement, quartz sand, grit, slag powder, copper ore, iron ore, gold sand, gravel, concrete aggregate various brittle material crushing and grinding is a kind of high efficiency and energy saving of gravel sand blasting equipment, than the traditional sand energy-saving 50%.

Working principle of impact type sand making machine：

Material from the upper part of the machine vertical fall into high-speed rotation of the impeller, in under the action of centrifugal force, and the other part to an umbrella form shunt in around the impeller material in the production of high-speed impact with the ground, material after the crash into each other, will between the impeller and the casing material form vortex multiple impact each other, friction and grinding, direct discharge from the bottom, forming many closed loop control by screening equipment to achieve the required fineness. When the broken ore particle size is smaller than the gap between hammer and impact plate, from the machine in the lower part of the discharge, is after the break of the products.
