The main features of the third generation of sand making machine is to crush the material efficiently, the machine is based on the working principle of various types of crusher, and based on user feedback on the specific use of information, combined with its advantages designed by the new high efficiency sand making machine (Crushing equipment). This machine is a rod mill sand making machine, impact sand making machine, straight sand making machine alternative. The third generation sand making machine is the principle and technology of "stone rock" crusher newly developed by our company. Combining with the actual situation of sand making in our country, we have developed high efficient stone crushing equipment with domestic, international and advanced level. Sand making machine is widely used in all kinds of rock, abrasive, refractory, cement clinker, quartz, iron ore, concrete aggregate and other hard and brittle materials in the broken, fine broken (sand). For construction sand, road gravel is suitable. HX vertical impact crusher by the feed, distributor, vortex crushing cavity, impeller experience, spindle assembly, base drive and motor seven parts. The third generation sand making machine features: (1) simple structure, low cost. (2) high efficiency and energy saving, high crushing efficiency. (3) with crushing, coarse grinding function. (4) Through non-crushing material ability, affected by the material moisture is small, water content up to 8%. (5) can be broken hard, special hard materials (such as corundum, sintered bauxite, etc.). (6) The product was a cube, iron pollution is small. (7) impeller and vortex crushing cavity material from the liner to significantly reduce the cost of wearing parts and maintenance workload. (8) operation and maintenance, easy installation. (9) Working noise less than 75 dB (dB), (10) Light weight, diverse installation, removable installation and so on.
