Gypsum Powder Drum Dryer Chemical Gypsum Cylinder Dryer Machine Plaster Calciner Plant

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.

Product Features

1. High heat efficiency. The principle of heat transfer of the cylinder dryer is heat conduction and the conducting direction keeps identical in the whole operation circle. Except heat loss of end cover and radiation loss, all heat can be used for evaporation of wet materials on the wall the cylinder. The efficiency can reach 70-80%.

2. Large operation elasticity and wide application. Various drying factors of the dryer can be adjusted, such as, temperature of heating medium, rotating speed of the drum etc. which can change drying speed of the under dryer. As these factors have no interrelations each other, it brings great convenience to dry operation and makes it applicable to dry various materials and to meet different requirements of production.

3. Short drying period. The drying period of materials is normally 10 to 300 seconds, so it is suitable for heat-sensitive materials.
