DetailProduct overview ：
After wet material from dryer into tube uniformly copy board machine, turn, the material in the dryer is uniformly distributed and decentralized, and flow (current) and a good contact with hot air, to speed up the drying heat transfer, to force. In the drying process, materials with gradient copy board and under the action of hot air, regulate movement to drier another star discharge valve to discharge the finished product.
Range of application：
Apply to 1. The chemical industry, mining, metallurgy and so on big particles, dry than major materials, such as: ore, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulphate (2) to have special requirements of powdery and granular materials dry, such as: slag HP vesicant, lees, light calcium carbonate, active white earth, magnetic powder, graphite, medical. 3. Require low temperature drying and continuous dry bulk materials.
Product features ：
1. The drum dryer high mechanization degree, large production capacity; 2. The fluid through the cylinder small resistance, low function consumption; 3. The adaptability to compare the characteristics of the material is strong; 4. Stable operation, low operation cost, the uniformity of product drying is good.
