Low price sand making machine(vertical shaft impact crusher)

Product Description

1.Introduction of the sand making machine:

Vertical shaft impact crusher is also known as sand making machine. It is widely used in metals and non-metallic ores, cement, refractory, abrasives, glass raw materials, construction aggregate, artificial sand and a variety of metallurgical slag fine and coarse grinding. It has more advantages than other types of crusher, especially in hard and abrasive materials, such as silicon carbide, carborundum, sintered bauxite, magnesite, etc. it can handle a variety of metallurgical slag

2.Operating principle:

The materials enter the crusher through feeder hopper, which is divided into two parts, one part through the middle of classifier entering into the rotating impeller at high speed, then accelerated, whose speed can reach hundreds of acceleration, then is shot through the tunnels around the impeller by the speed of ****5 meter/second.

First the materials will impact with some materials fallen around classifier, then impact on the whirlpool cavity's skateboard together, then will be rebounded and impact on the top of the whirlpool cavity, then changes its direction and goes down, forms continual material layers with the materials shot from the impeller.

Therefore some materials will be impacted, crusher, milled twice or more times in the whirlpool cavity, then crushed materials will be excluded through the bottom discharging hole. This can from a closed circulation through the circular classifier system; in general, materials can be crushed into *0 meshes through thrice circulation. Airflow self-circulation in the whirlpool cavity can eliminate the dust pollution well.

3.Features:
1. Simple structure and low operating cost
2. High efficiency and low consumption
3. It can fine crush crude grind material and it is easy to maintain.
4. It is slightly influenced by the humidity of material and the max humidity is 8%.
5. It is more suitable for crushing mid-hardness materials.
6. Its products are cubic, the density of piling up is high and the iron pollution is low.
7. The working noise is less than *5 decibels and dust pollution is light.

4.Main technical parameters:
