Rotary drum dryer DDHG series

cylinder

From mining to processing, coal can be divided into different types of products such as raw coal, clean coal, and coal slime. In practical applications, the moisture content of the coal will affect the quality of downstream industrial products or the operation of boiler. Our company has developed the coal dryer line in order to improve the quality and storage and transportation performance of coal. Coal dryer system are designed according to the characteristics of different coal to ensure the efficient and safe operation during the dying process.This coal dryer plant has the advantage of large processing capacity, low energy consumption, low drying cost, etc. System Firstly, the raw material (crushed if needed) transported to the rotary drum dryer by the belt conveyor. Because of the inclination of drum dryer, material with hot air moves to the end of dryer body, during which process wet material gets fully contact with the hot air. After drying, most of the dry material is discharged through the belt conveyor. The left material mixed with dust continue goes into the cyclone dust collector and the bag dust collector in sequence, where the dust will be collected. Lastly, with the function of induced draft fan, the left material will discharged through the conveyor. Advantage a. The operating parameters can be changed according to the nature of different materials, so that the material in the drying cylinder to form a balanced dispersion of the state, the heat exchange more fully; b. New inlet and outlet devices eliminate plugging, discontinuities, inhomogeneities, and feed back of the tumble dryer, and reduce the load on the dedusting system;
