Sludge Ceramsite Sand Rotary Kiln
2025-08-30
1. Working Principle
( 1 ) The main chemical components of sludge are SiO2、Al2O3 oxides and organic matter, among which SiO2、Al2O3 sinter with the base material to form a structural skeleton providing strength. Organic matter decomposes during firing to produce gas, promoting the expansion of ceramsite and helping to reduce its density.
( 2 ) The roasting temperature of ceramsite is generally around 1200 °C. All organic matter in the sludge decomposes, pathogens and parasites are killed by high temperature, harmful heavy metals are encapsulated in glassy phase or fixed in new crystal phases at high temperature, solidified in the ceramsite. The sludge treatment is thorough, environmentally harmless, and does not affect the performance of the ceramsite product.
Raw materials are mostly municipal sludge, paper sludge, dyeing sludge, electroplating sludge, pickling sludge, leather sludge, oil-based mud, drilling cuttings, shale, fly ash, general clay, construction waste soil, remediation soil, contaminated soil, coal gangue, etc.; heat sources can be coal, natural gas, or biomass fuel.
2. Burner Selection
- Gas Burner
Fuel: natural gas, liquefied petroleum gas, blast furnace gas, coke oven gas, light hydrocarbon gas, rice husk, bran, etc.;
- Oil Burner
Fuel: diesel, methanol, heavy oil, alcohol-based fuels, etc.
- Pulverized Coal Burner
Fuel: pulverized coal
Currently, the most commonly used by users is natural gas burner and Pulverized Coal Burner . 300 Currently, our company's daily sludge rotary kiln project with a capacity of 2023 tons has been officially in production since 4 year 
month.
