Rotary Drum Dryer for sale
Rotary dryer is used for drying material with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. It can be used for drying many kinds of materials such as limstone slag, coal powder, clay stone etc.
Characteristics:
It has advantage of reasonable structure, high efficiency, low energy consumption. Rotary dryer mainly consists of rotary body, raw material feeding plate, lifting blade, driving and supporting device, sealing ring and etc.
Working principle:
The raw material plate which is arranged reasonably with chargeable angles in order, throws moisture materials into the rotary cyclinder. The water will be separated from the materials by hot air-flow and changed into vapour to be discharged into the atmosphere. Then the material would be dryed.
Rotary drum dryer application:
The rotary drum dryer of our company, also called dryer. It is widely used in building material, metallurgy, chemical engineering, and cement industries for the drying of slag lime stone, powdered coal, slag and clay. This dryer consists of rotary body, throwing flitch, transmission device, supporting device and sealing ring. It has the features of reasonable structure, fine processing, high output, low energy consumption, and convenient running.
Main features of rotary drum dryer:
1.The dryer is of strong overload capacity resistance, large process load, low fuel consumption, and low cost.2.It adopts direct flow drying method. The gas fume and the material go to the dryer from the same side. By using the hyperthermia gas fume, the evaporation strength is very high. With the low outlet temperature, the heat efficiency is very high. 3.The operating parameter can be changed according to different materials. So that the material can form a stable fabric curtain and achieve fully heat exchange.4.The new type feeding and discharging device solve the problem of feeding jam, discontinuous and uneven feeding, and returning charge which lighten the load of dedusting system. 5.The new inner structure strengthens the cleaning and heat conduction of the dispersed material, and eliminates the bonding in the inner drum wall. The adaptability to the material moisture and stickiness is stronger.6.The zero level thrust of the dryer reduces the abrasion to the catch wheel and the riding wheel. The operation of the rotary drum is stable and reliable.7.The dryer adopts the riding wheel device, which make the riding wheel and the rolling ring linear touch all the time. Thus the abrasive and the power loss are greatly reduced.8.The granularity and the moisture and be controlled by the customer’s demand. When drying the coal slurry, the product moisture can be less than 8% and the granularity and be less than 8mm.
