diesel burner cylinder dryer clay drum dryer machine clay rotating dryer plant

Brief introduction of rotary dryer :

Rotary dryer is widely used for drying slag limestone, coal powder, slag, clay, etc. Dryer can also be used in building materials, metallurgy, chemical and cement industry. Rotary Dryer mainly consists of dryer body, raw material feeding plate, driving and supporting device, seal ring, etc. Dryer can be generally divided into four types, they are: rotary dryer, triple-drum dryer, indirect heat transfer dryer, vertical dryer. Different kind of dryer has its own characters and advantages, the specific choice of a special dryer depends on different elements.

Rotary dryer internal structure of the lifting plate type :

In order to increase the material evenly distributed on the cross section of the cross section and the drying medium has good contact, in the cylinder body install lifting plate,. There are several kinds of lifting plate for the rotary dryer:

1. Lifting type Lifting plate: suitable for large lump material or easy to be bond in the wall of the material.

2.Four grid type lifting plate: applicable to large density, not brittle or not easily dispersed material. The lifting plate will divide the inside cylinder into four grid, will form a fan operation room not communicating with each other, the contact area of the material and the hot air is larger than the lifting type,and it can increase the material filling rate and reduce material falling height and reducing the amount of dust loss.

3. cross shape or frame shape plate: suitable for more brittle and easily dispersed small pieces of material, so that the material can be evenly distributed in the entire section of the cylinder.

4. sleeve type lifting plate: for multiple heat transfer (or semi diameter heating) rotary drum dryer.

5. cellular type (fan) plate is suitable for fine particles and easy to cause the powder fly. When material feeding is piled up in the lattice board, when the cylinder rotates, the material is stirred and constantly in contact with hot air, at the same time for the material landing height decreases, reducing the possibility of drying materials taken by hot air.

In various forms of lifting plate above can be distributed throughout the whole rotary dryer cylinder, in order to cause the material to quickly and evenly to the lifting plate,can install screw guide material plate at the feed end of 1~5m, in order to avoid the accumulation of wet material bonding on the cylinder wall. At the same time because of dry material is very easy to be raised and was taken away by the waste gas, and in the discharge end of the 1~2m is not installed any lifting plate.

Features of Rotary Dryer

Highly various material from the feed screw directly into the breaking drum dryer, the plate is on the inner wall of the roller against taking the fall. Break bulk material with a negative pressure of the high temperature medium full contact, complete heat transfer process. Since the inclination and the action of the draft fan, the material from the feed end to the discharge end to move slowly, and then in the discharging end airflow extraction, via the conveying pipe after further drying into the dust, the airlock discharge. 

Advantages of our rotary dryer 

1. The rotary speed is adjustable ,control moisture to be some extent. 

2. The dryer can dry high moisture content and large volume materials.

3. There is elastic plate sealing strip in feed inlet and outlet , improve heat usage efficiency . 

4. There is lifting blade in the inner cylinder, it can make the material mixed with the heat flow fully.
