In the process of modern machinery industry development, With the rapid development of China s economy, sand making industry has gone through the extensive development stage where relying on cheap work advantage and environment destruction, follow the international trend of the development of low-carbon economy, sand making industry toward being actively explore the development path of energy conservation and environmental protection. the R & D department of our company based on the development of the domestic industry, the most advanced sand making equipment, with the overall smooth operation, high efficiency, crushing than the advantages of large equipment to play its vital role in its territory project. Let s look at theVSI sand making the entire process of our company work: the materials are fed into the hopper through the central inlet into the rejection of high speed rotating wheel, the round rejection was quickly accelerated up to tens of several times the acceleration of gravity acceleration, drive from the wheel rejection and high speed, hit another part of the material with the rebound after to free-fall first, and then with the impact of the material lining or counterattack block, rebound oblique impact to the top of the vortex chamber, but also to change its direction of movement, deflected downward movement from the impeller material emitted impact to form a continuous material curtain. In this way, a piece of material in the vortex crushing cavity by multiple impacts, friction and abrasive. So as to achieve the effect of prepared sand, and the crushed material is discharged from the lower discharge port. Some moisture in the body s internal raw material compound, sand making heat, moisture evaporation, and the whole pipe interface imprecise, the outside air is drawn into the circulation increased pressure to ensure that the sand making machine in the state of negative pressure.

There are many types of sand making machine, and their application field are very wide too, like our company, we have VB Sand (stone hit stone overflow type), the VSI type sand making machine (Stone), the Type PCL sand making machine (stone blacksmith type). Sand making machine is widely used in mines, gravel pits, abrasives, cement, refractory material, bauxite, quartz sand, silicon carbide, glass, and other industries in the waves, crushing and shaping. The sand making grinding technology is a new technology developed with the emergence of modern high technologies and new materials industry. because of the extensive, cutting-edge and practicality of sand making industry, it has a very important strategic position in the national economy as a whole.
