Shale Rock: Geology, Composition, Uses
Shale has many commercial uses. It is a source material in the ceramics industry to make brick, tile, and pottery. Shale used to make pottery and building materials requires little processing besides crushing and mixing with water. Crushing shale and heating it with limestone makes cement for the construction industry.

Effect of Shale Sample Particle Size on Pore Structure …
The mercury intrusion and extrusion processes of shale with coarse (before sample crushing process; Figure 12(b)) and fine particle (after sample crushing process; Figure 12(c)) are divided into 5 stages: low pressure intrusion, high pressure intrusion, higher pressure intrusion, high pressure extrusion, and low pressure extrusion.
The six main steps of iron ore processing
The aim of this step is to ensure a smooth crushing process and minimise downtime in the event of a breakdown or to allow planned maintenance in the crushing system, without stopping the grinding and other further steps. If the crusher breaks down, the performance of the entire factory may be affected. 3. Feeding the crusher (Reclaim)

Crusher equipment and pulverizing mills for shale crushing …
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.
Oil Shale
The shale oil is then refined of impurities, such as sulfur. In Situ . In situ is a new, experimental method of extracting shale oil. During the in situ process, oil shale is not mined or crushed. Instead, the rock is heated to its oil window while it is still underground. One technology used for in situ oil extraction is known as volumetric ...
