Chinese Sandstone Association clearly pointed out that: the excellent artificial sand quality should be reconcile sand / artificial sand / powder / mud / natural sand / the weathered sand / reconcile sand dam. At present, due to the considerable demand for artificial sand, some enterprises which do not have the quality of producing sand began to use the simple making machine to produce sand, of course, the sand they produced is unqualified, which not only causes the user to pay a much greater cost than usual, the more serious is the concrete produced can not achieve the requirement, this directamente impacts the quality of the construction work. The following is the third generation which is truly suitable for the production of artificial sand maker: The application of the third generation sand make machine (sand-making machine): This series of sand applies to the soft, medium hard and extremely hard materials makers crushing, plastic, which is widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building sand, stone, and each kinds of metallurgy slag, especially for silicon carbide, silicon carbide, sintered bauxite, sand US high-hard, especially the hard and the other corrosion-resistant materials. In the engineering industry, it is the ideal equipments of producing mechanism sand, cushion material, asphalt concrete and cement concrete aggregate. And so on. In the mining industry, this product is widely used in the preceding process, it can grinding produces large amounts of iron ore purposes, reduces the high cost of grinding load. As the excellent low wear characteristics of this sand maker, this device is also used for high abrasive and secondary disintegration crushing production series.
In addition, due to the zero pollution to production, crusher can well adapted to the production of glass quartz sand and other high purity materials, in the scale off10-500t / h production capacity, this crusher can meet almost any production requirement. The working principle of the third generation sand making machine (sand-making machine): The material is fed from the hopper to the crusher, and be feed divided into two parts by the sub-feeder, part of them go through the middle of the sub-feeder into the high-speed rotation of the impeller, being rapidly accelerated in the impeller, its acceleration gravity can achieve to several hundred times, and then projectile out from the impeller three runner uniform at the speed of 60-70 m / s, the first part of the same sub-feeder four weeks from the closing material falling crusher, and with the impact of the vortex cavity lining materials material lining rebound oblique impact to the top of the whirl chamber, and then change the direction of motion, deflected downward movement of material emitted from the impeller form a continuous pipes curtain. In this way, the material be crushed, fracted and grand in the whirl crushing cavity twice as well as several times. The broken material is discharged from the lower part of the discharge opening. During the whole crushing process, the materials are impacted crushing to each other, don t contact with the metal components directamente but with the lining materials shock, in This way, the angle is reduced pollution, the time of mechanical wear is extended.
