Coal slime is a by-product produced during coal washing and coal preparation. Coal slime can be roughly divided into: flotation tailings from coking coal preparation plant, coal slime produced from coal-water mixture, and slime entrained in mine drainage etc. No matter what type of slime it is, it generally features the characteristics of high moisture content, high viscosity, high ash content, low heating value, fine particle size, floating in wind and running with water.
In view of the characteristics of slime, it is difficult to dry. Even after dehydration, the water content of the slime is about 30%.The "rotary-harrow Material-crushing Triple-phase Multi-loop" slime dryer produced by China ZJN and the unique technology of "using boiler exhaust gas waste heat" can minimize the cost of thermal energy while drying wet slime up at one go.
"Rotary-harrow Material-crushing Triple-phase Multi-loop" slime dryer adopts the integrative doubled triple-sleeves mode and a unique rotary harrow crushing device to quickly disperse wet materials, increasing the contact area of sludge particles and hot air while effectively preventing the slime particles from sticking and agglomerating during the drying process. The technology of "using the waste heat of the boiler exhaust gas" can make use of client's existing thermal energy resources. While reducing operating costs, it can also use wet sludge to remove harmful substances in exhaust gas. The slime dryer has a large drying capacity and high heat energy utilization rate, so it is the best choice for coal washing, coal preparation plants and the coal miners.
