Shale rock is a type of sedimentary rock formed from clay that is compacted together by pressure. They are used to make bricks and other materials that are fired in a kiln. Shales characteristically consist of at least 30 percent clay minerals and substantial amounts of quartz. They also contain smaller quantities of carbonates, feldspars, iron oxides, fossils, and organic matter.
Shale is too soft and too easily broken into small pieces to be used as dimension stone.
Shale rock crushing and grinding process
The whole process of shale comminution usually consists of primary crushing, secondary crushing, and fine crushing. Shale rocks of different sizes are inserted into the jaw crushers for size reduction. Generally grinding is carried out in one or two stages, while three grinding stages can also be performed. After crushing, the material is returned to the sieving process for sizing. Depending on the desired output size of the crushed stone, the raw material may be fed to one or two impact crushers, cone crushers, or complete stone grinding mills in a sequence. Thereafter, the crushed stone is transmitted to the vibrating screen to the size gradation. The product is handled by a conveyor belt to various places of exploitation, such as the jaw crusher to the vibrating screen.
Shale crushing equipment recommended by Baichy Machinery
Jaw crusher is used in primary crushing, and an impact crusher is used in secondary crushing after a jaw crusher.
Based on quarry conditions, mobile crushers are also used in quarrying because of their convenience, high capacity, and automation. To produce shale powder, a pulverizing machine is necessary in the shale powder processing plant. The commonly used grinding mills are ball mills, Raymond mills, vertical mills, trapezium mills, coarse powder mills, ultrafine mills, etc.
As for the selection of crushers and grinding mills for shale processing, Baichy Machinery strongly recommends the following processing and crushing plant equipment for you. Among the various types of crushers, you can choose our PE series jaw crusher, C series jaw crusher, impact crusher, hammer crusher, cone crusher, and so on.
