Brief Introduction to Artificial Sand Making machine

The VSI sand maker, also known as the impact crusher, has replaced traditional equipment, such as the hammer crusher, roll crusher, rod mill, etc. Artificial sand maker proves to be the most essential equipment in the sand making industry. The sand making machine in our company is developed by introducing the 'stones crush stones' working principle and technology from the United States and combining the actual domestic sand production conditions, making a leading high efficiency sand making equipment of world level.

Features of Sand Making machine

1) VSI sand maker is the newly developed equipment in the 1990s for medium and fine crushing, also the widely used one for replacing cone crusher, roller machine and ball mill.

2) Novel and unique structure, smooth operation.

3) Low energy consumption, high productivity, high crushing ratio.

4) Small size, simple operation, easy installation and maintenance.

5) Cubic shape and bulk density.

6) Protection layer, no abrasion, durability.

7) Hard wear-resisting materials, small volume, light weight, convenience.

Working Principle of Sand Making machine

1. Center Feeding: raw material falls down into feed hopper, and then enters impeller through central entrance hole. It is accelerated in high-speed impeller, and then is thrown out at a speed of 60-75m/s. When hitting impact plate, it is crushed. Final products come downwards though outlet.

2. Ring Feeding: Raw material falls down into feed hopper, and then through ring, it is divided into two parts by material-dividing plate. One enters into impeller through the center of material-dividing plate. The other falls down from outside of material-dividing plate. Material, which is thrown out by impeller at speed of 60-75m/s, hits material coming down from outside of material-dividing plate. In this way, material is crushed.
