Indirect Heat Transfer Dryer:

1. Appliation:

The indirect heat transfer dryer made by our company is mainly used in building materials, metallurgy, chemical industry cement plant, which is suitable for drying high-humidity large-proportion materials such as slag, limestone, clay, sand, quartz sand,granulating slag, etc.

2. Working principle:

The raw material plate which is arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder.

Then water will be separated from the materials by hot air-flow and changed into vapour to be discharged into the atmosphere. Thus the materials would be dryed.

3. Advantages of indirect heat transfer sand dryer machine

• The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.
• strong overload resistance capacity, large capacity, low fuel consumption, low drying cost; 
• the dryer adopts downstream drying method, hot air enters into the dryer with wet material, which obtains high evaporation intensity by high temperature air; temperature in dryer outlet is low, with high thermal efficiency;
• the dryer can change operating parameters according to different material properties, with high quality and sufficient heat exchange;
• the dryer adopts new feeding and discharging devices, putting an end to feeding jam, discontinuity, non-uniform phenomenons of vertical dryer, reducing the load of dust-removing system;
• the dryer achieves "zero horizontal thrust", greatly reducing the wear of gear wheel;
• the dryer adopts self-aligning roller device, wheel and roller ring contact each other in a line, thereby greatly reducing wear and power loss;
• product moisture can be controlled according to user requirements.
