Brief Introduction of Mixing Process of Sludge Ceramsite Mixture

Ceramsite has the characteristics oflight bulk density, loose and porous inside, and low thermal conductivity. Ithas become one of the main raw materials of building material blocks. Therefore,the ceramsite industry has also developed rapidly. The main types of ceramsiteare shale ceramsite, fly ash ceramsite and clay ceramsite. Among the rawmaterials of ceramsite, sludge is also one of the main raw materials, and theproportion of sludge ingredients is about 10-30%.

As the state attaches importance to theenvironmental protection industry, current policies encourage the addition ofsludge to the raw materials of ceramsite and give ceramsite manufacturers acertain amount of sludge treatment fees. In summary, the ceramsite industry hasdeveloped rapidly, and the number of new ceramsite factories and blockfactories in China is increasing.

Among the raw materials of sludgeceramsite, sludge accounts for about 10-30%, and clay or shale accounts for70-90%. The specific ratio needs to be adjusted according to the moisturecontent of the material and the test effect of ceramsite. Due to the specialnature of the sludge itself, weight loss, belt scales and other equipment aregenerally used for weighing and transportation. The clay or shale powder can beweighed and conveyed by belt scales, screw scales and other equipment.

After the sludge is weighed and mixedwith clay or shale, it needs to be pre-mixed in the mixing equipment. The conventionalmixing equipment has a double shaft mixer. The double shaft mixer can adjustthe speed of its frequency conversion motor according to the characteristics ofthe amount of materials and the nature of the materials to achieve theprocessing capacity required by the process.

The materials mixed by the double shaftmixer can mix the sludge with clay, shale, etc. initially, which is convenientfor the later material aging and granulation.

Henan Zhengzhou Mining Machinery Co.,Ltd. is committed to the research of sludge ceramsite industry and equipmentmanufacturing in line with the tenet of "Morality gose before work, profitgot later than others". It is a company that integrates equipmentmanufacturing and process design. Through the supply, design and debuggingexperience of multiple actual ceramsite production lines, we can providecustomers with high-quality mechanical equipment and mature process technologyservices.
