Analysis of the crushing process of granite and other stones

Granite, basalt, diabase, river pebbles and other stones have high hardness and high silicon content. They are materials that are difficult to crush or have high crushing costs in crushing operations. In actual production, we must fully consider the investment cost and practicality of the production line in order to obtain greater investment income.

The following are three typical process schemes:

1: Vibrating feeder + jaw crusher + impact crusher + vibrating screen
2: Vibrating feeder + jaw crusher + fine jaw crusher + impact crusher (optional according to needs) + vibrating screen
3: Vibrating feeder + jaw crusher + cone crusher + impact crusher (optional according to needs) + vibrating screen

It is not difficult to see that in the above scheme, the main difference is whether the secondary crushing is the impact crusher-based impact crusher, or the extrusion crushing-based fine jaw crusher or cone crusher.

In many stone yards that do not have high requirements for the finished size of the stone, customers are more willing to use jaw crushers, fine jaw crushers or cone crushers to build production lines. Because both jaw crushers and cone crushers belong to extrusion crushing, the wear on the wear parts is relatively small, and the production cost is relatively low. However, due to extrusion, the crushed stone will have a poor grain shape. The content of needle-like stone is relatively high, and the internal cracks of the stone are more serious. High-grade buildings or other materials are generally unwilling to accept this type of stone. , So the market price will be very low.

The larger feature of the impact crusher is that it can produce high-quality granular stone, with the dual performance of crushing and shaping; the good-granular stone can add better stress performance to the building, and it has a higher sales in the market. Of course, the wear cost of wearing parts of the impact crusher is also higher than that of the fine jaw crusher and cone crusher of the same output.
