As we all know, granite is a kind of building material with a very wide utilization rate, but in the process of mining and grinding granite, there will be a lot of leftover materials. According to incomplete statistics, the granite quarry produces hundreds of millions of tons of granite waste materials every year. It is a pity if so many granite waste materials can not be reasonably utilized.
As a result, many investors with insight have taken a fancy to the processing market of granite leftover materials, that is, the whole crushing production line is selected to process it into construction sand. So as to give full play to the waste heat of granite leftover materials and realize the reuse of "waste materials", the economic value and industrial significance of this is self-evident.
So the question is, what equipment should be used to break granite leftovers into sand? What are the corresponding supporting equipment?
What equipment is usually used to break granite leftover materials into construction sand? In view of the high hardness of granite, it is generally recommended to select "jaw crusher + cone crusher + vsi series sand making machine" for joint processing, which is more suitable for producing machine-made sand of various specifications.
1. Jaw crusher
The diameter and particle size of some granite leftover materials are large, so jaw crusher will be selected for preliminary rough crushing processing. The equipment is simple in structure, and all kinds of high, medium and low hardness stones can be broken. In addition, the equipment has the characteristics of high crushing efficiency, large output, small volume, simple installation and flexible operation.
2. Cone crusher
Cone crusher is a machine specially used for crushing high hardness stone. With hydraulic structure design and laminated crushing raw materials, the stone crushing effect is good, and it saves oil, electricity, environmental protection and energy conservation, it is a good choice for the second breaking equipment of granite leftover materials.
3. VSI series sand making machine
VSI series sand making machine is a new type of crusher, which integrates multiple patents and three crushing modes. It is the key equipment to provide excellent aggregate for highway, railway, bridge, water conservancy and hydropower industries, with outstanding performance and reliable quality.
