Firstly, the raw material transported to the screw conveyor by the belt conveyor, then go into the rotary drum, after drying, most of the dry material will be discharged through the belt conveyor, the left material will go into the cyclone dust collector, where the dust will be collected, with the function of induced draft fan, the left material will discharged through the conveyor.
◆ Compared with single pass rotary drum dryer, the triple pass rotary drum dryer saves about 50% floor area, 60% electricity consumption;
◆ Low outlet temperature, long lifetime of dust cleaning system;
◆ Adopt new type lifting boards, and the output moisture content can be adjusted as customer's demand;
◆ High degree of automation, simple operation, stable working;
◆ Equipment investment needed is only 1/6 of the imported equipments. Low investment, creat profit quickly;
◆ Adopt gear transimission, small transimission power needed;
◆ Broad fuel choice: coal, diesel, natural gas, waste wood, etc.
