Rotary Tube Drying Machine

Rotary Tube Drying Machine Classification

According to the drying medium and the heat transfer between the wet material into direct heat rotary tube drying machine (drying medium in direct contact with the wet material to transfer heat) and indirect heat transfer drum dryer (dry heat required by the indirect cylinder wall passed to the wet material) two. Low indirect heat transfer drum dryer transfer efficiency and structure of complex reasons, less preferred, this does not describe. Direct heat rotary tube drying machine, drying medium and material in the direction of flow, downstream and upstream is divided into two. The main part of the direct heat transfer drum dryer is a horizontal line slightly tilted rotating cylinder. The cylindrical gear speed is generally 2 ~ 6r / min, the inclination of the cylinder about its length, usually between 1 бу ~ 5 бу. Material from the higher section of the drum into contact with hot air, with the rotation of the drum, the flow of materials under the action of gravity and the lower end of the discharge is dried. Since the dryer is working under negative pressure conditions, feeding and discharge end seals are used to prevent air leakage.

Rotary tube drying machine dryer is a large number of materials processing. Since reliable operation, operating flexibility, adaptability, large capacity, widely used in metallurgy, building materials, food, light industry, chemical industry, coal, medicine and mining industries. The machine is generally adapted to granular materials, it can also be incorporated into the material used for some way to dry and sticky paste materials or with higher water content. Advantages drum dryer production capacity, wide application, low flow resistance, the operation allowed large fluctuation range, easy to operate. Commonly used in the dryer sand, ore, coal, manure, dung.

Rotary Tube Drying Machine Working Process

Rotary tube drying machine at work: the wet material from the belt conveyor or bucket elevator to the hopper, then through feeder hopper into the feeding side through the feeding pipe. Feeding pipe slope is greater than the natural inclination of the material to a smooth material flow into the dryer. Rotary tube drying machine is a cylinder slightly inclined to the horizontal rotating cylinder. Material from the higher end of the join, the heating medium from the low-end entry into countercurrent contact with the material, but also the heat carrier and the material together and flow into the cylinder. With the rotation of the drum material by gravity to run to one end than the end. Wet material in the cylinder body to move forward the process, directly or indirectly, to heat the heating medium of the wet material to be dried, and then the discharge end by the belt or screw conveyor sent. Contact surfaces in the cylinder body wall equipped with copy board, its role is to copy the material up and planted, so that the material and increases airflow to improve the drying rate and to promote material progress. Heat carrier is generally divided into hot air, flue gas. After rotation through the heating medium rotary tube drying machine, cyclone will generally require gas trapped within the material brought down. For further reduce exhaust gas dust content, but also through the bag filter or wet dust collector and then put emissions.
