Shale is a kind of accumulation rock with complex composition, but it has thin lamellar or lamellar joints, It is a rock composed of clay accumulation under pressure and temperature, mixed with quartz, feldspar debris and other chemicals.
Ceramsite block is light in weight, good in thermal insulation, low in thermal conductivity, good in impermeability and fire resistance, These advantages make ceramsite block very popular in the construction industry. The natural shale is not fixed in shape and cannot meet the needs of the industrial field. Therefore, it needs a series of processing and production to meet the market demand.
The shale sand production line is mainly composed of crushing equipment, sand making equipment, screening equipment, feeding equipment, transportation equipment, etc. in the whole sand production process, there is no need for too many personnel to operate. Shale materials move evenly among various processes, the production line has large disposal capacity and high production efficiency. The process steps are as follows:
1. Crushing - primary processing.
Natural shale shall be initially broken by jaw crusher. Jaw crusher has strong destructive capacity and high cost performance ratio. However, due to the low hardness of shale, cone crushers can be used for crushing processing. When any material is initially processed, appropriate equipment must be selected according to its characteristics.
2. Sand making - the core of production.
Sand making is the core of the whole production process, and the selection of sand making machine is particularly important. The sand making machine produced by SMMVIK Machinery has been in the forefront of the industry and is your first choice. The shale sand making machine is mainly used to trim the broken shale to make the particle size of shale materials more uniform and the particle shape meet the requirements. The shale produced by the sand making machine of SMMVIK Machinery is controllable, with large production volume and little dust pollution in the production process.
3. Screening - control specifications.
The screening equipment often selected in the screening process is the circular vibrating screen. As it is a relatively reliable screening equipment at present, it can simply and effectively control the specifications of shale products. The circular vibrating screen produced by SMMVIK Machinery can adjust the machine according to the needs of customers to screen out materials that meet the specifications for the next procedure. Those that do not meet the requirements will be eliminated.
4. Washing - selecting finished products.
Through screening, qualified shale products enter the sand washing machine for cleaning. After cleaning, they enter the dryer for drying. After that, the required shale products are obtained. The sand washing machine and the dryer are selected according to the production needs of users.
