Basalt is high hardness and high silicon content in the actual crushing operations is more difficult to crushing, or breaking the higher cost of materials. Popular speaking, basalt is hard material, and high silicon content.

Therefore, basalt reasonable to design the crushing process, consider breaking the project investment cost, we must take into account the production cost of the production line.

Basalt is used in construction (e.g. as building blocks or in the groundwork), making cobblestones (from columnar basalt) and in making statues. Heating and extruding basalt yields stone wool, an excellent thermal insulator.

Basalt grinding mill is widely used in metallurgy, building materials, chemicals, mining minerals in areas which need to pulverize basalt. According to the fine grinding of basalt and discharging basalt fineness, basalt grinding mill can be divided into Raymond Mill powder machine, vertical roller mill, high-pressure powder mill types.

Cast stone producing process with basalt as the raw material. The process includes four working procedure:

1. Pulverize-crushing basalt into small pieces and grinding them into powder with basalt crusher and basalt mill.

2. Dissolve-melt the basalt into flux in the melting furnace.

3. Molding- flux in the mould cools off.

4. Anneal- the demolding shape relief annealing in the annealing furnace.
