Brief Description of Shale Sludge Ceramsite Process

Ceramsite has the characteristics of light volume density, loose and porous inside, low thermal conductivity, etc., at present, it has become one of the main raw materials of building material blocks. Among the raw materials of ceramsite, sludge is also one of the main raw materials, and the proportion of sludge ingredients is about 10-30%.

As the state attaches importance to the environmental protection industry, current policies encourage the addition of sludge to the raw materials of ceramsite and give ceramsite manufacturers a certain amount of sludge treatment fees. In summary, the ceramsite industry has developed rapidly, the number of newly-built ceramsite factories and block factories in China is increasing.

Ceramsite can be divided into: shale ceramsite, clay ceramsite, coal gangue ceramsite, etc. The main raw materials of shale ceramsite are shale and sludge. Shale ceramsite system can be divided into: shale crushing, drying, grinding, batching, aging, granulation, firing, cooling, and finished product conveying system.

The shale raw material has a large particle size and contains a certain amount of water, so it needs to be crushed and dried. After the shale is dried, it needs to be ground, and after being ground to a powder, it is weighed and conveyed by the conveying equipment. After the shale powder and sludge are measured by the measuring equipment, they are sent to the mixer for mixing. The agitated mixture is sent to the aging warehouse through the conveying equipment for aging. The aged mixture enters the granulation system for granulation. After the granulation, the raw ceramsite enters the plug-in kiln for roasting, then cools through the cooler, and enters the finished product conveying system.

Henan Zhengzhou Mining Machinery Co., Ltd. is devoted to the research of the sludge ceramsite industry and the equipment manufacturing in line with the tenet of "Virtue in advance, benefit after people".It is a company that integrates equipment manufacturing and process design. Through the supply, design and debugging experience of multiple actual ceramsite production lines, we can provide customers with high-quality mechanical equipment and mature process technology services.
