Deep Rotor VSI Sand Making Machine
Deep rotor vsi sand making machine is a new sand making equipment set three broken mode in one,which adopts the international advanced technology and combined with the characteristics of China's crushing industry. It is fully reflects the new technologies, new processes.Now this sand maker has become the core equipment of artificial sand and stone industry and increasingly become the metal ore, quartz sand, steel slag mainstream processing equipment.
Nowadays, this new type vsi sand making machine is suitable for crushing different kinds of ore and rock stone with high hardness.This sand machine is a high energy and with international advanced level sand making equipment, which plays an irreplaceable role in all kinds of ores fine crushing plant because of its unique performance. It's the currently most effective, practical and reliable crushing sand making machine.
Widely Application Of Sand Making Machine
- 1. It is widely used in mechanism of sand stone, construction aggregate, high grade highway, asphalt concrete and cement concrete aggregate mining production line;
- 2. Building materials, metallic and non-metallic minerals, chemical industry, mines, refractories, cement, construction aggregate,and other industries.
- 3. Used for medium and fine crushing of various rock stones and ores , such as iron ore, quartz sand, basalt,non-ferrous metal ore, perlite, bentonite,corundum, bauxite and other materials.

Sand Making Machine Working Principle
From the hopper into the crusher, the sub-feeder the material is divided into two parts, sub-feeder from middle to high-speed rotation of the impeller, and is rapidly accelerated in the impeller, its up to several hundred times the acceleration of gravity, then speed of 60-70 m / s projectile from the impeller flow channel in three out of uniform, the first part of the material with the impact of the feeder surrounded by falling broken self-closing, and then went to the impact on the vortex branch cavity lining materials, top is lining material rebound oblique impact on the whirl chamber, but also to change its direction of motion, deflected downward movement, rotation Road materials emitted from the leaves to form a continuous material curtain.

Such a material in the whirl crushing cavity by two or even several times the probability of impact, friction and grinding crushing effect. The material to be broken by the lower row of the discharge port. In breaking down the whole process, the material on their own mutual impact crusher, not in direct contact with the metal components, but the impact of the occurrence and lining materials, friction and grinding, which reduces the angle of pollution, to extend the mechanical wear and tear of time. Whirl ingenious internal cavity airflow from the circulation, eliminating the dust pollution.
Unique Performance Feature And Advantages
- 1. deep cavity rotor design is optimized, so that the material throughput increased by about 30%.
- 2. weeks shield can wear down a U-turn after topical use, improve material utilization, can improve the life of more than 48%.
- 3. modular design hammer, hammer part simply replace worn, can reduce the cost by more than 30%. Also increases the hammerhead, effectively prevent damage after the main hammer wear vertical plate.
- 4. the most important core of wear-resistant materials used by the US industries with highly wear-resistant high-temperature materials.
- 5. the optimal transmit port and internal smoother curved design, reduce the flow resistance of the material, greatly improve the capacity of the material.
- 6. selection of high protection class motors. This type of motor has a high efficiency, low noise characteristics. In line with the International Electrotechnical Commission (IEC) standard, F class insulation, IP54 / 55 protection rating.
Routine Maintenance Method
Sand making machine internal wear of routine maintenance is essential, must regularly make sand maker get adequate downtime, and to regularly observe sand machine, if worn should be replaced or repaired. Also note that in the normal course of their work sand making equipment is never open to observe in order to avoid the risk of accidents.
When sand maker at work 400 hours should be the addition of appropriate amount of grease, to work 2000 hours to open the spindle assembly bearing cleaning, if the work until 7200 hours it must be replaced with new bearings.
