The rotary dryer machine, or drum dryer is drying equipment to dry various materials such as sawdust, and rice husks, controlling the water content ranging from 10%-12%. This kind of sawdust drying machine always works with the charcoal production line to produce high-quality coal briquettes.

What materials can be dried by a rotary drum dryer?

Drum dryer is suitable for drying many kinds of materials, such as sawdust, rice husks, coal powder, ore, gypsum, wood chips, wine dregs, grain, fruit peel, sand, organic chemicals and so on. Whether it is wet ore or wet wood chips, the rotary dryer machine can efficiently complete the drying task and dry the materials to the specified humidity.

Applications for rotary dryer machine

It is mainly used to dry wet materials, so as to reduce the humidity of the materials and improve production efficiency. This equipment is widely used in various industrial fields, such as mining, metallurgy, construction, chemical industry, etc., and can dry a variety of materials.

Working principle of the rotary drum dryer machine

The working principle of the drum dryer is relatively simple and efficient.

Step 1: Material feeding

The material enters the drum through the feeding device, usually with the help of a screw conveyor.

Step 2: Heat exchange

The material exchanges heat with the fuel inside the rotating cylinder, generating high-temperature hot air.

Step 3: Material Rolling

Material rolls and turns in the rotating cylinder, and is gradually dried by gravity and hot air.

Step 4: Moisture Discharge

During the drying process, the moisture is discharged through the exhaust port, thus realizing the rapid drying of the material.

Why use the rotary dryer machine in the charcoal production line?

The rotary dryer machine plays an important role in various production lines. In charcoal production lines, it is often used for the front end of the line. Whether the charcoal is carbonized using a charcoal furnace or directly made into sawdust briquettes, the raw material requirement is 10%-12% moisture. Therefore, this dryer can effectively help you process raw materials on a large scale
