Crusher equipment and pulverizing mills for shale crushing processing plant

We provide various types of shale crushing grinding machine for shale powder production line. Jaw crusher, cone crusher, impact crusher, ball mill, fine powder grinding mill are the most commonly used ones.

Shale rock properties and applications

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 material that is 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 or even as crushed stone (although some shale is used as “slate” for garden walkways and paving stones). The greatest potential use of shale today is as a new source of oil. It is presently estimated that 1.75 x 1015 barrels of oil are trapped in the world’s oil shales. This is 100 times the total liquid petroleum geologists expect will be removed from known oil reserves.

Positioned on the resource-rich ground of the original site, red shale brick uses native red shale mined from our on-site quarry guaranteeing consistent quality and processing integrity. Added to this native shale are water drawn from deep wells, filtered and tested regularly, and the finest sand from across the country to create red shale bricks.

Shale rock crushing and grinding process

The whole process of shale comminution usually consists of primary crushing, secondary crushing and fine crushing. Shale rock 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. Product is handled by a conveyor belt to the various places of exploitation, such as jaw crusher to the vibrating screen.

Shale crushing equipment recommended by the engineers

Typically, jaw crusher is used in primary crushing, and impact crusher is used in secondary crushing after jaw crusher. Usually, on the basis of quarry conditions, mobile crushers are also used in the quarrying because of its 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 mill, Raymond mill, vertical mill, trapezium mill, coarse powder mill, and ultrafine mill, etc.

As for the selection of crushers and grinding mills for shale processing, our engineers 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, JC series jaw crusher, impact crusher, hammer crusher, cone crusher and so on. In terms of shale grinding mill, ball mill, Raymond mill, vertical mill, MTM trapezium mill and medium speed super thin grinding mill can be your choice.

Our company is a manufacturer of mining and construction machinery in China. We can supply all kinds of crushers and grinders such as aggregate crusher (limestone crusher, marble, granite crusher, gravel ), coal crusher, cement mill, concrete crusher, gold ore mining equipment and so on. Since we are professional in the crushing and processing of shale, we can design and manufacture shale ore production line according to your requirements.
