The Lack of Artificial Sand Can Be Resolved with the Development of VSI Sand Mak

September 14, 2017

As is known to all, in recent years, with the constant development of many industries like construction, the demand of natural sand is increasing constantly. However, in order to protect the environment, there is a policy against natural sand exploitation in China, which leads to the increase of the price of sand resource. In order to resolve the lack of artificial sand, to adopt the sand manufacturing system is the optimal choice to meet the requirement recently.

In the artificial sand production process, the material is sent into the crushing machine with the feed hopper. Some of the material is sent into the center of the high-speed rotating impeller. Then, the impeller is accelerating so that its speed can be hundreds of times as fast as the force of gravity. Besides, during the exploitation process of some non-metallic ore and metallic ore, there will be lot of tailing, which can be utilized to realize energy conservation and emission reduction.

The VSI sand maker is a common crushing machine, which is known for its big crushing ratio, simple structure, and convenient maintenance. In the great market, with the constant advance, the VSI is becoming a kind of typical product. Then, what kind of VSI sand maker can catch up with the development trend mentioned below?

Firstly, the designer should advance the inner structure of the VSI sand maker, especially the structure of hammer plates and the rotor, to increase its crushing capacity of hard rock and its flexibility in maintenance. The advance of the structure of the crushing cavity of the machine can increase its crushing ratio and the energy use ratio. Secondly, the research on the wear-resistant material for the hammer plate can help prolong the service life of the VSI sand maker. Besides, the VSI sand maker is being developed towards standardization and large scale to meet the requirement of clients and the whole market. Then, we should insist on the technical innovation in the development of the VSI sand maker.
