shale ore crusherShale is a fine-grained, clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. The ratio of clay to other minerals is variable. Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility. Mudstones, on the other hand, are similar in composition but do not show the fissility.
Before the mid 19th century, the terms slate, shale and schist were not sharply distinguished. In the context of underground coal mining, shale was frequently referred to as slate well into the 20th century.
The crushing process of shale
The big raw shale are fed to the jaw shale crusher evenly and gradually by vibrating feeder through a hopper for the primary crushing. After first crushing, the material will transferred to impact shale crusher or cone shale crusher by belt conveyor for secondary crush; the crushed materials will then transferred to vibrating screen for separating. After being separated, the crushed shale parts that can meet standard will be taken away as final products, while the other shale parts will be returned to impact shale crusher, thus forming a closed circuit. Size of final shale products can be combined and graded according to customer's specific requirement. We can also equip dust catcher system to protect environment.
