Introduction of three drum dryer

It is widely used in drying granule material in fixed moisture range,such as yellow ground in dry mortar industry,all kinds of molding sand in casting industry and blast furnace slag in building material/cement industry.Small size clay,small granule material in chemical industry which cannot happen chemical effect,high temperature resistance and not have strict control to smoke.

Performance Features:

Three-cylinder dryer is designed for the material of low moisture, moderate proportion, liquidity changes generally in drying process. With compact structure,less covering area, is one-half of the same output single cylinder drying covers, reliable, low energy consumption, high thermal efficiency,good material drying effect and easy to realize automatic control,few operators.

1, The wearable of alloy steel plate manufacture is 4 times than the ordinary, machine maintenance is very small.

2, The outlet temperature is low,long-time use of the dust removal device.

3, The use of wheel rotation, transmission power is small.

4, Speed to arbitrarily regulate, and materials, wind, and coal three parameters process

Working principle of the three-cylinder dryer

The wet material is put into the dryer after dehydration. The material can disperse evenly and contact fully with the hot air in the dryer through the stirring of the plate which is in the roller. Thus quicken the speed of drying, heat transferring and mass transferring. In the process of drying, the material can be sent out by the star unloading valve which is in the other end of the dryer under the action of the gradient plate and the hot mass.
