How vertical shaft impact crusher works for sand making?
vertical shaft impact crusher
The vertical shaft impact crusher (also called sand making machine) is a highly effective sand crusher. It is a high-energy, low energy consumption, with the international advanced level of similar products, the introduction of foreign outstanding technology development. Currently, it is the most advanced and practical medium crushing and shaping equipment.
Utility of Vertical shaft impact crusher:
This crusher machine is widely used for crushing and rough grinding in the industry, such as:
1, River gravel, rocks (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, artificial sand stone chips.
2, Construction aggregate, highway fabric, cushion material, asphalt concrete and cement concrete aggregate production.
3, Water conservancy and hydropower engineering, highway, highways, high-speed rail passenger line, bridges, airport runways, municipal works, the mechanisms of sand production of high-rise.
4, buildings and stone plastic. The grinding of the mining areas of the preceding crushing crushing of materials technology, building materials, metallurgy, chemical, mining, refractories, cement, abrasives industry.
5, High abrasion resistance and secondary disintegration of crushing, thermal power, metallurgical industry, in addition to sulfur, slag, construction debris, broken and other environmental projects.
6, Production of glass, quartz sand and other high purity materials.
Working Principle of Vertical shaft impact crusher:
Into the high-speed rotating impeller on things and other things around the impeller, because the high-speed centrifugal force. They strike each other, touch the impeller and the casing between the vortex. Through repeated impact and friction, crushed into small pieces, and straight to the lower things. Cyclic operation. And then reached the fineness of the product.
Materials into the crusher feed hopper, the material is divided into two parts by the sub-feeder, the feeder middle part by the high-speed rotation of the impeller, impeller centrifugal acceleration, the acceleration of up to several hundred times the acceleration due to gravity, and then 60-70 m / sec from the impeller three uniform flow within the projectile out, first with self-closing down around the feeder part of the material impact crushing, and then with the impact to support vortex cavity lining materials, material lining rebound in oblique impact on the top of the eddy chamber, but also to change its direction of motion, deflected downward movement of material emitted from the impeller to form a continuous material curtain. Such a material in the vortex dynamic crushing cavity by two as well as several times the probability of impact, friction and grinding crushing effect, was crushed into small pieces, and straight to the lower things. The broken material is discharged from the lower part of the discharge opening. And form a closed loop screening system, three general circulation can be broken material into less than 20 mesh. The whole under the crushing process, the material of mutual self-impact crusher, not in direct contact with the metal components, but the material lining the impact, friction and grinding, which reduces the angle of pollution, to extend the time of mechanical wear. Ingenious airflow inside the whirl chamber circulation, eliminate the dust pollution.
