Mineral waste residue dryer can dry many different raw materials contain moisture, such as sawdust, coal, coal slurry, sand, slag, grain, fertilizer and other wet materials. They are widely used in building materials, metallurgy, and chemical industry. 
        Rotary dryer consist of rotary body, lifting blade, driving device, supporting device, sealing ring. 
        Heating source can be coal, charcoal, wood, gas, electricity, oil, wind power, etc.

Working principle of Mineral waste residue
        (1)Wet materials are sent to dryer by conveyor belt or elevator, or in order to feed materials continuously and smoothly, you can add a feeder.
        (2) When installation, the drum need have a 3-5º inclination, to ensure the materials move from the upper part to lower part smoothly.
        (3) In upper part, we can make a fire in brick heating stove, clean hot air enter pipes in rotary body,  revolving body make hot air drying biomass material  gradually. 
        (4) Dry biomass materials come out from the lower part, then you can make deep production or other usages.

        Lantian series grain drying machine is professional biomass dryer, mainly used to dryer small biomass materials, sawdust, wood pieces, grain, coconut shell pieces, rice husk, agricultural wastes, etc.

        (1) It is the indirect type rotary dryer, there are 31 pipes in it, hot air enter pipes directly.
        (2) Hot air in the pipes, biomass materials outside, so biomass materials can avoid be ignited.
        (3) Indirect heating source prevent raw materials pollute by smoke and dust. 
        (4) Special design can make hot air circulate in rotary drum body, and shorten drying time. 
        (5) Brick heating stove, there are three walls in it with different functions, special structure can prevent smoke, flame and dust enter pipes, just enter clean hot air. 
        (6) Heating source can be coal, charcoal, wood, gas, oil, wind power, etc.
