Cement rotating dryer is one kind of dryer machine, which is mainly formed with the main body, front roller circle, rear roller circle, gear, gear roll; pinion, discharging part, plate, reducer, motor, hot air channel, feeding chute, furnace body, etc, and we can design it with coal gas producer, combustion chamber or supporting hoist, belt conveyor, quantitative feeder, dust collect cyclone, induced draft fan, etc. according to the needs of users. Cement rotating dryer is mainly used for drying material like building material, metallurgical industry, clay, coal dust, metal selected mining and so on.
Distribution of variety of circumferential material lifting device can effectively regulate and control the drying time with a good drying effect. Secondary center lifting device and new combined lifting device are adopted to ensure no wind tunnel phenomenon of materials and improve heat exchange efficiency. Cement rotating dryer can set heating, drying, dust collection as a whole, to achieve operating mechanization and automation, and meet environmental requirements. Supporting high-temperature flue gas roaster can burn materials rapidly to provide adequate and high thermal efficiency heating with a coal consumption lower than 15kg of standard coal/ton dry material.
The sleeve column structure of cement rotating dryer can timely shorten the length of the dryer, and substantial reduction of the cooling surface can lower heat consumption. Meanwhile, the multiplicative heat exchange surface can greatly improve the thermal efficiency. For materials can not contact with smoke, multi-drum rotary dryer can provide smoke pipe and the annular pipe respectively in the inner and outer cylinders connected with radial flue, which is also energy-efficient.
