As Chinese coal slime drying industry set design, production, sales in the integration of science and technology enterprises. After nearly 20 years of rapid development, Dingli has gradually become a steadily drying equipment industry in China and the first brand of the company. Company based on the current coal, blue carbon industry market, technical research and practice, case study, developed the coal chemical industry of coal, blue carbon drying drum system before carbonization,which also often used in LAN charcoal half coke dry quenching cooling, recycling heat energy, or used in LAN charcoal carbon coal cooling and dry raw material coal series to use, fully recycled hot charcoal carbon coal heat, as raw material to the depth of coal moisture removal. This set of equipment technology is advanced, stable running, convenient operation and maintenance.

This type of equipment available to dry all kinds of coal, carbon coal, charcoal, anthracite coal, lean coal, lean coal, coking coal, fat coal, air fertilizer in coal, gas coal, coal and weakly caking coal, not sticky coal, long flame coal, lignite, coal washing, screening, raw coal, bituminous coal, the tail coal, coal, coal, etc. Equipment can be made according to the customers' requirements.

Coal drying technology is divided into drum drying and drum distillation units-two kinds of technology. Drum drying means adopting rotary drum dryer for drying to reduce the water moisture, its products are high heat value quality coal; Drum drying distillation technology refers to using rotary drum dryer and rotary distillation machine together, the dryer dehydration and heat of coal , dry distillation machine dry distillation of lignite removal volatile part and the internal moisture, the product is high heat value, low sulfur, low water moisture, low volatile of dry distillation upgrade coal .
