Shale 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. According to the causes, shale can be divided into magmatic rocks (or igneous), sedimentary rocks (or sedimentary rocks) and metamorphic rocks. The raw material for sintered bricks produced by shale vacuum brick machine is sedimentary rocks. Although the weight of sedimentary rocks is only 5% of the earth's crust, they are distributing in the earth's crust surface area, and the percent is 75%. Therefore, edimentary rocks are an important rock as the raw material of making bricks.
Shale crusher is used for fine crushing of raw material before into grinding mill in mining, cement plant. Shale crusher is widely used in manufacturing factory of new wall materials made from coal gangue, shale. Shale crusher solved the problems of raw materials with high moisture crushing. With rationale particle allocation, small investment, small occupied space, few operating personnel, economic and effective operation and other advantages, shale crusher is widely used in fuel workshop of thermal power plant. Shale crusher can replace jaw breaker, ring-hammer crusher and fine grinder etc. Shale crusher is especially suitable for the production of perforated brick and thin-walled brick, therefore, shale crusher is mostly used in the brick making enterprises those are using coal gangue and shale to produce new type bricks.
