Цилиндрическая сушилка для горных работ гипсовый порошок Роторная штукатурная

Product introduction

Rotary dryer are endowed with large drying capacity, smooth working, low energy consumption, easy operation, high yield advantages. The dryer according to the different materials characteristics, set up different types of lifting plate and in case of sticky measures, the material feed in the inner of rotating cylinder drying, as well as multi-angle lifting by the plate, so that the material raise uniform full and high-temperature hot air for heat exchange. Drying effect high,external cylinder with shaking devices to prevent the material sticking on the wall.

Industrial Dryer 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.

Applications of Rotary Dryer:

Industrial Dryer 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.

How to improve rotary dryer’s efficiency 

1. Improving temperature of drying medium of rotary dryer. 
2. Improving flow rate of drying medium.
3. Improving internal structure of cylinder body of rotary dryer, adopting combined raise material.
4. Reducing material feeding granularity
5. Using concurrent processing set-up where possible 
6. Adopting step-less speed regulator

Working Principle

1. Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator.

2. Materials enter the barrel installed with slope to horizontal line from the higher side, and hot air enters the barrel from the lower side, and then materials and hot air mix together.

3. Materials go to the lower side by gravity when the barrel is rotating.

4. Lifters on the inner side of barrel lift materials up and down in order to make materials and hot air mix completely, which is designed to improve the producing efficiency of rotary dryer.

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.

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.
