Works; material from the hopper into the crusher, the sub-feeder the material into two parts, vertical Sand, in part by sub-feeder middle to high-rotating impeller being rapidly accelerated in the impeller, which up to several hundred times the acceleration of gravity, and then at a rate of 60-70 m / sec projectile out of three from the impeller uniform flow channel, the first part of the material with the impact of the sub-feeder from around since broken down, and with the impact on the vortex branch cavity lining materials, were material lining rebound, PCL Sand, oblique impact on the top, aggregate sand whirl chamber, but also to change its direction of motion, deflected downward movement, from the leaves channel transmission material turns out to form a continuous material curtain. Such a material whirl broken twice by the cavity and repeatedly hit probability, friction and grinding crushing effect. The crushed material from the lower discharge port discharge. In the whole process under the crushing, sand making machine, material mutual self-impact crusher, not in direct contact with the metal element, but with a lining material impact, friction and grinding, which reduces the pollution angle to extend the mechanical wear and tear of time. Whirl ingenious internal cavity flow from circulation, eliminate the dust pollution. Use editing 1, river gravel, rocks (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, the artificial sand stone chips. 2, construction aggregate, highway road fabric, cushion material, asphalt concrete and cement concrete aggregate production. 3, water conservancy and hydropower engineering, highway, highway, railway, passenger railway, bridges, airport runways, municipal engineering, high-rise buildings and stone shaping sand production. 4, the mining industry front crushing grinding process, building materials, metallurgy, chemical, mining, refractories, cement, abrasive material crushing and other industries. Double roll Sand | Sand | Building Ceramic plant matter Building Ceramic plant supplied by Boshan matter. Boshan matter of Building Ceramic plant (www.bsshida.com/) strong, credible, Shandong Zibo crushing grinding equipment industry has accumulated a large number of loyal customers.
