Product introduction

The rotary drum dryer is a type of industrial dryer employed to reduce or minimize the moisture content of the material it is handling by bringing it into direct contact with a heated gas. Rotary drum dryers are  customized equipment for your specific requirement. Our design team are able to design rotary drying equipment which can effectively save your budget and efficiently running.

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

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.

Working Principle

Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator. The barrel is intalled with slope to horizontal line. Materials enter the barrel from the higher side, and hot air enters the barrel from the lower side, materials and hot air mix together. Materials go to the lower side by gravity when the barrel rotates. Lifters on the inner side of barrel lift materials up and down to make materials and hot air mix completely. So drying efficiency is improved.
