1. General description of Rotary Drum Dryer
Rotary drum dryer is a kind of drying equipment used to reduce moisture content of the material , and can be used for drying coal, coal slurry, brown coal, fly ash, gypsum, clay, Kaolin, mineral powder, slag, iron powder, mill scale, sludge, sawdust/wood chips, chicken manure, feed etc.
It is widely used in building materials, metallurgy, cement and mining industry. it has features of reasonabl structure, excellent fabrication, high production, low consumption, economical &environmental etc.
2. Working principle of Rotary Drum Dryer
The main body of roller drum dryer is a cylinder at a certain gradient with horizon. The cylinder is drove by gear at a speed of 2-6r/min. The general gradient of cylinder is about 1°-5°. Materials enter cylinder by the upper end. As the cylinder rotates, materials flow to the lower end under gravity and get discharged. During this period, materials get thorough contact with hot air, moisture inside gets vaporized. Due to dehydrating machine operates under negative pressure, the inlet and outlet both adopt sealing device to avoid air leakage.
