High Heat Efficiency Small Rotary Dryer Machine
Brief Introduction of Coal Rotary Dryer
Mine Rotary Dryer is widely used to dry materials in industries like cement, mine, construction, chemical, food, compound fertilizer. The Bentonite Rotary Dryer heat source comes from the combustion apparatus. Small Dryer adopts concurrent heating method. For this reason, the materials to be dried go into the cylinder from the feeding box or feeding chute and then pushed back by the spiral lifting board. As the dryer machine is obliquely put, the materials flow to the lower end under gravity and the rotation of the cylinder on one hand, and on the other hand, the materials will be repeatedly lifted by the lifting board to upper end and scattered down, so that the materials will form a even material curtain inside the cylinder and carry out sufficient heat exchange with the heat airflow inside the cylinder. As the materials are repeatedly scattered, the water containing in the materials will be gradually dried, thus reaching the goal of drying.
Features of Rotary Dryer Machine
1. High heat efficiency. The principle of heat transfer of the cylinder dryer is heat conduction and the conducting direction keeps identical in the whole operation circle. Except heat loss of end cover and radiation loss, all heat can be used for evaporation of wet materials on the wall the cylinder. The efficiency can reach 70-80%.
2. Large operation elasticity and wide application. Various drying factors of the dryer can be adjusted, such as concentration of feeding liquid/thickness of material film, temperature of heating medium, rotating speed of the drum etc. which can change drying speed of the under dryer. As these factors have no interrelations each other, it brings great convenience to dry operation and makes it applicable to dry various materials and to meet different requirements of production.
3. Short drying period. The drying period of materials is normally 10 to 300 seconds, so it is suitable for heat-sensitive materials. It also can be pressure reducing operated if it is put in vacuum vessel.
