Rotary Dryer

Rotary Dryer

The main production of Henan Dajia Mining Machinery are kiln, lime kiln, ceramic kiln, rotary kiln zinc oxide, limonite rotary kiln, chemical kiln, lime kiln, etc.

Description

Our company produced rotary dryer using the new rotary drum dryer lifting plate that have a guide, average current, lifting and many other features,make the material in the dryer full uniform radial cross-section,act is expected to become thin, uniform, complete , complete contact with hot air, to make full use of thermal energy. Our rotary dryer using reasonable operating parameters, coal consumption and electricity consumption lower 10-15% than the average dryer, the production increase10-15%, it has been widely used in the cement and mineral processing enterprises .

Structure of rotary dryer

Rotary dryer device mainly include:cylinder device,front and rear roller device, feeding and discharging device, gearing device, gear cover and other components. (With dryer associated ancillary equipment: combustion chamber, feeding material equipment, dust collection equipment, etc. do not belong to the local scope).

We supply the following dryer: wet material rotary dryer, sand dryer, sawdust dryer, coal dryer, coal slime dryer, bentonite dryer, ore concentrate dryer, wood chip dryer, cassava dryer, gypsum dryer, cow dung dryer.

Application of rotary dryer

Rotary dryer is suitable to dry metallic and nonmetallic mineral, clay in cement industrial and coal slime in coal mine,etc. Rotary dryer can be widely used to dry various materials, and it is simple to be operated. Rotary Dryers have many applications but are most commonly seen in the mineral industry for drying sands, limestone, stones and soil, ores, fertilizers, wood chips, coal, iron sulphate, filter cakes, sewage sludge, etc. Rotary Dryer is widely used in the field of building materials, metallurgies, chemical industry, cement and so on. It can dry slag, coal powder, mining powder, clay, sand, limestone and so on. It is made into rotary body, lifting blade, driving device, supporting device etc.

Advantages of rotary dryer

1. Reasonable structure

2. High efficiency, low energy consumption

3.Convenient for transportation

4.Convenient and reliable operation

 

Characteristics of rotary dryer

1. The internal adopts assembled structure which has improved the accuracy of the equipment and it is easy to transport and

install.

2. According to the characteristics of different fertilizers ,we have arranged the second granulation zone reasonably so as to

improve the granulation effect .

3. Adopts assembled hoist board so as to exchange heat fully and lower the energy consumption .

4. Temperature induction monitor ,uniform vibration and airproof setting , which improve performance and productivity efficiently .

Working principle of the rotary dryer

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.
