Overview

Industrial drum dryers are equipment that achieves material drying through the rotation of a drum. Also known as roller dryers or rotary dryers, they represent the most common and widely applied drying equipment within industrial machinery. Drum dryers are employed to process substantial quantities of raw materials and find extensive use across industries including metallurgy, building materials, chemicals, coal, pharmaceuticals, and mining. Commonly dried materials encompass sand, mineral powder, coal dust, chicken manure, and cattle manure.

The composition of the drum dryer

The drum drying equipment is mainly composed of the rotating body, lifting plate, transmission device, supporting device, and sealing ring. It adopted the new type of material lifting plate device that has multiple functions such as guidance, flow sharing, material lifting, etc. It can make the material distribute evenly in the radial section of the dryer and the material curtain becomes thin uniform, and complete. So that it can fully contact the hot gas flow tov achieve the purpose of making full use of heat energy.

Features of the roller-type dryer

1.Advanced drying technology, using high-temperature rapid drying technology, large heat transfer coefficient, high thermal efficiency, and high drying strength;
2.The dryer has a high degree of automation and does not require too much manual operation. The system operation realizes automatic control and adjustment. Reducing production safety hazards and improve drying efficiency;
3.Large fluctuation range allowed in operation, easy to operate;
With the direct contact between the hot gas flow and the material, the output can meet the needs of different users from 10 tons to 100 tons per hour under the condition of sufficient heat exchange;
4.The drum dryer has strong expandability, and the design takes into account the production margin. Even if the output increases slightly, there is no need to replace the equipment;
