Rotary Drier

1. Description of Small Rotary Drier:

1. Rotary Drier machine is depending on the practice in sand and stone production, absorbing the leading technology home and abroad, and is widely used in sand making industry.

2. The Small RotaryDryer machine is of high efficiency and has the features of reasonable structure, high capacity and low consumption.

3. The Small Rotary Dryer machine can make final products free from dirt and impurities and reduce the high quality sand loss.

2. Application of Small Rotary Dryer:

Rotary Dryer machine is widely used in a variety of materials drying operations. As reliable operation, convenient operation, strong adaptability, large capacity, it is widely used in metallurgy, building materials, food, light industry, chemical industry, coal, medicine and mining industries.

Rotary Dryer machineis suitable for drying granular materials in general. It can also be mixed with some materials by drying sticky paste materials or materials with higher water content. Commonly used in dry sand, slag, coal, animal waste and so on.

3. Structure of Small Rotary Dryer:

The Rotary Dryer machine consists of the cylinder, before and after the roller circle, a large gear, gear roll, drag roller, a small gear, a feeding device, lifting plate, reducer, motor, feeding device and other components. Furnace can be designed according to user needs, the combustion chamber, bucket elevator, belt conveyor, feeder, dust and other system equipments.

4.Working Principle of Small Rotary Dryer:

Small Rotary Dryer machine is handling by bringing it into direct contact with a heated gas.

The dryer is made up of a large, rotating cylindrical tube, the dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under.

5.Working principle:

Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer.

When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls.

This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow).

The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer.

Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated.

When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type.

Often, indirect heated dryers are used when product contamination is a concern.
