rotary tube drying machine

Drying is a very important mining production a program. According to Shanghai SBM company’s technical personnel, dryer (industrial dryer, slime dryer) is mainly used for drying materials iron ore, titanium, and other minerals such as quartz sand certain humidity or granularity. Rotary tube drying machine adaptability of materials that can dry various materials, and the equipment is simple and reliable, it has been widely used with reasonable structure, well-made, high-yield, low energy consumption and ease of operation.

Drum dryer, also called rotary tube drying machine, is a lot drier material handling. As reliable operation, operating flexibility, adaptability, processing capacity, widely used in metallurgy, building materials, food, light industry, chemical industry, coal, medicine and mining industries.

work principle of rotary tube drying machine

Wet and dry material from the belt conveyor or bucket elevator to the hopper, and then by feeding hopper feeder through a pipe into the feed end. Pitch feeding the natural inclination of the pipe is greater than the material, so the material smoothly flows into the dryer. A dryer cylinder is slightly inclined to the horizontal rotating cylinder. Material from the higher end of the join, the heating medium enters from the lower end, into countercurrent contact with the material, but also the heating medium and material together and flow into the cylinder. As the drum rotates the material by gravity to run to one end than at the end. Wet material in the cylinder body to move forward the process, directly or indirectly, to heat the heat carrier of the wet material to dry, then the discharge end by the belt or screw conveyor sent. Contact surfaces in the cylinder body wall mounted copy board, its role is to copy the material up and planted again, so that the material and increases airflow to improve the drying rate and to promote material progress. Heat carrier is generally divided into hot air, flue gas. Heat carrier through the dryer after the cyclone will generally require gas trapped within the material brought down. To further reduce exhaust gas dust content, but also through the baghouse or wet dust collector and then put emissions.

Performance characteristics of rotary tube drying machine

The rotary tube drying machine is mainly composed of rotary body, lifting plate, gear, support equipment and seals and other components. With a reasonable structure, well-made, high-yield, low energy consumption, easy operation and so on. Rotary tube drying machine is generally adapted to granular materials, can also be incorporated into the material used for some way to dry and sticky paste materials or materials with higher water content. The advantage is that the production capacity of large, wide application, flow resistance, allow greater volatility in the operating range, and convenient operation.
