    Product Description

    According to the working principle, the slime dryer is a rotary drum dryer or rotary drum dryer. It is a mature drying equipment produced by mining equipment manufacturers, and is suitable for drying slime, sludge, magnetic, heavy, flotation concentrate of metal and non-metal mines, clay of cement industry and other industries in the coal mine industry.


    Feature


    1. The dryer has strong overload resistance, large processing capacity, less fuel consumption and low drying cost;


    2. With the downstream drying method, the flue gas and wet materials enter the dryer from the same side, which can obtain high evaporation intensity with high temperature flue gas, low outlet temperature of the dryer and high thermal efficiency;


    3. The operation parameters can be changed according to the properties of different materials, so that the materials can form a stable fully broken fabric curtain in the dryer cylinder, and the mass and heat exchange is more sufficient;


    4. The new feeding and discharging device solves the problems of feeding blockage, discontinuity, nonuniformity and return of the drum dryer, and reduces the load of the dust removal system;


    Working principle



    When the lignite coal dryer on operation, the belt conveyor feeding materials into feeding hopper. Materials go to the lower side by gravity when the lignite coal dryer’s barrel rotates. When the material inside the drum fluidization of lignite coal dryer , boiling hot wind and touch it thoroughly drying. The auto-combustion device from lignite coal dryer provides heat resource for our dryer, which adopts down-flow heating method. Scatters of lignite coal dryer will fly materials up and fall them down.

    Why choose this Coal Slime Rotary Dryer ?



    The coal slime itself has high humidity and high adhesion. The traditional dryer fails to address this feature. The special dryer for coal slime produced by Hongke heavy industries uses a special dispersal device, which can disperse the bonded coal slime and dry it, increasing the contact area between the coal slime and the hot air, and greatly improving the heat utilization rate. The moisture content of the dried coal slime can be reduced to less than 12% at one time, and the dried coal slime can be directly used as fuel. Make slime waste into treasure. In addition, after years of unremitting efforts, the R&D Department of our company can use the boiler exhaust gas as the heat source of the slime dryer and successfully launch the boiler exhaust gas dryer. There is no investment in heating and no cost in using heat. Energy saving and drying, energy saving and environmental protection.
