What Is the Dryer Machine Made Up of ?

As we all know that the

Rotary dryer is the material heating drying equipment, which is widely used in cement,mining,building material,chemical industry,drying pulverized coal,limestone,grain,sand,clay materials,etc. But do you know what the dryer nachine ismade up of?

The dryer equipment adopts self-aligning type tug structure, the tug and with good tyre-roller, greatly reduce the wear and tear of power consumption. Resistance to overload ability, cylinder smooth operation and high reliability. This was also important when a wide range of speed control was necessary for a sensitive operation such as wire drawing or hammering iron. Under sub divided power, steam was piped from a central boiler to smaller steam engines located where needed.

The rotary dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. 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 gravity. 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.

Rotary dryer processing capacity, fuel consumption, dry low cost less. 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.

And this gas stream of dryer machine 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...
