TVSI single motor sand making machine

TVSI single motor sand making, also named the 4^th generation of sand making, is one of the world's most advanced equipment of sand making. After being improved and designed by Tarzan according to the domestic requirement of sand making, it is the most advanced high-performance sand making equipment in China at this moment. It is widely used in metal ore or non-metallic minerals, cement, refractory, alumina, emery, glass material, building material, artificial sand making, and variety of metallurgical slag crushing. For medium or special hard material, it has more advantages than other type of crushing equipment. TVSI single motor sand making machine works with 2GP roll crusher, the finished concrete can achieve above C60 standard. 

Feature:
1. Simple structure, stable operation
Through continuous improvement and optimization, this kind of equipment is easier for operation and has simplified structure but guarantee the high performance at the same time. Its rotor structure is completely heat treated, with SKF or NSK imported bearings; add vice throw device, equipped with lubrication automatic control system. The whole structure is solid and operates stably.
2. Energy efficient, high crushing efficiency
The sub-feeder is fixed in the top of the crushing cavity. It can gradually speed the materials which enter into the rotary impellers through central feed tube to higher speed for throwing. It can increase the product capacity and crushing efficiency without increasing power consumption.
3. Simple operation, easy maintenance
Hydraulic adjustment of feed port, simple operation, hydraulic lift device, more convenient and quicker maintenance.
4. Longer life, less dust pollution
During the crushing process, materials are impacted and crushed by each other, no directly contact with metal components. They are only impacted, rubbed with the material lining, thus prolong the machine wear time. The eddy cavity internal clever air circulation eliminates the dust pollution.

5. Automatic operation, safe and more reliable
It adopts circulation lubrication system for spindle bearings, which can guarantee continuous oil supply to main engine, and realize automatically control and accident alarm.
6. It can be used as shaping machine, and control the content of needle-flake products under 5%. 

Principle:
Material enters the crusher through feed hopper. A part of material enters the high-speed rotary impeller from the upper sub-feeder and they are speeded immediately inside the rotating rotor. The speed can reach hundreds of times the acceleration of gravity. Then material is thrown through the passage around the rotor by the speed of 60-75M/S. It is first impacted and crushed with the material falling from the overflow port around the hopper, and then both of them are impacted to the crushing cavity lining and rebounded by the material lining, up-obliquely stroke to the top of the eddy cavity. Then it moves along down-obliquely and forms a continuous material curtain with the material from the impeller passage. Just like this, the material is impacted, rebounded, crushed twice or more, then it discharge from the bottom discharge port. It forms a closed circulation with circular screening system. Normally after three times circulation, material can be crushed to less 4.75mm. The crushing cavity internal clever air circulation eliminates the dust pollution.
