Cement Rotating Dryer

Overview

Cement rotating dryer is one kind of dryer machine 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. Our company 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 to dry materials like building materials, metallurgical materials, clay, coal dust and so on.

Characteristics

1. Secondary center lifting device and new combined lifting device are adopted to ensure no wind tunnel phenomenon of materials and improve efficiency of heat exchange.  

2. Distribution of various circumferential material lifting devices can effectively regulate and control the drying time with a good drying effect.

3. Supporting high-temperature flue gas roaster can burn materials rapidly to provide adequate and high-thermal efficient heating with a coal consumption lower than 15kg of standard coal/ton dry material.

4. Cement rotating dryer can set heating, drying, dust collection as a whole, so as to achieve operating mechanization and automation, and meet environmental requirements. 

Working principle

The sleeve sets 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 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.
