The vertical shaft impact crusher, also called sand making machine and rubble shaping machine, is a kind of crusher impacted by the materials themselves. It is of high energy but low consumption and of international advanced level developed by introducing foreign outstanding technology of the same type of products. At present, it is the most advanced and practical equipment for medium-sized and fine crushing and shaping.
It is widely used for medium-sized and fine crushing and shaping in the following industries: minerals, quarry, abrasive, cement, refractory materials, alumina, quartz sand, and emery, glass and so on.

The materials fall into the impeller from the head of the machine and with the function of high-speed centrifugal force, they strongly hit against and highly grind the other parts of the materials bypass flowing around the impeller in an umbrella form. After mutual impaction and between the impeller and the machine shell, the materials will move like a vortex and will be impacted, rubbed and pulverized many times. Then they will come to the required fineness controlled by screening equipment, and discharge from the bottom of the machine.

Features

1. It features of simple structure, high crushing efficiency and low operation cost.

2. It can fine crush and pre-grind materials and the crushed products are of cubic shape.

3. The affection from the humidity of materials to the machine is little.

4. It is suitable for crushing materials of medium, high and super hardness.

5. It works by stones hitting stones, so there is little wear for the machine and it can save energy and is of low consumption.

6. The grade and the fineness of the sand for construction after being washed can be up to the national standards, such as “sand for construction” and “cobble and broken stones for construction”.

7. It features of fine stabilization, low noise. And because it crushes materials in the cavity, the dust pollution is little.

8. When used along with the rod mill and ball one, it can simplify the flowing process, lessen the energy consumption, improve the production efficiency and cut down the cost to a large degree.
