VSI sand making machine is suitable for the broken of soft, hard and extremely hard materials. It is widely used in a variety of ore, cement, construction and other materials, gravel material. Material will put into the sand machine from the hopper and then divided into two parts by the impeller top distributor, part of material with high-speed rotation into the impeller cavity, the impeller cavity is rapidly accelerated at the same time, the material cone to the material in the form of umbrella evenly placed in the impeller of the flow channel, the speed instantaneous growth rate to 65-74 m/s and immediately ejected from the flow mouth, this time first by the impeller top distributor around the fall of a part of the material impact broken, and then confluence and impact to the guard panel and the material lining above, and then ejected again, once again rushed to the top of the turbine chamber, and then deflected downward movement, the impeller hammer again after the impact of the cavity to the direction of the shell brakes to form a continuous material curtain. Such a material in the vortex was twice or more times the impact, impact, friction and grinding broken, broken material from the lower discharge port discharge. The entire process of breaking the material in the material and lining between the material also occurred in the continuous impact of friction to crush, while the cavity of the clever flow of gas and gas circulation, will reduce the dust generated in the collision and reduce pollution.

The features:

1. High capacity and high yield, compared with traditional equipment with equivalent power, the output will increase by 30%.

2. Vulnerable parts consumption is low. The optimal impact angle design of the broken dirty material greatly reduces the damage bag of wear-resistant parts, which is 30% lower than the operating cost of traditional equipment.

3. Excellent grain shape.

The finished product is cubic, the grain shape is good, grade is reasonable, fine modulus can be adjusted. It has unique advantages in artificial sand and stone shaping.
