Rotary Dryer - Efficient Hot Gas Direct Contact Design, Energy-saving Operation | High Performance For Building Materials, Metallurgy, And Chemicals

The Rotary Drying Equipment is widely used in the field of building materials, metallurgies, chemical industry, cement and so on. It can dry slag, coal powder, mining powder, clay, sand, limestone and so on. It is made into rotary body, lifting blade, driving device, supporting device etc. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation.This series drier is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. The Rotary Drying Equipment can be used for drying many kinds of materials and with convenient and reliable operation; therefore, it has been widely used
The Rotary Drying Equipment is composed of rotary cylinder, lifting blade, driving device, supporting device, sealing ring. Material is fed at one end and discharged at the other end. In direct-type rotary dryers, hot gases move through the cylinder in direct contact with the material, either with or against the direction of its flow. The cylinder is equipped with flights, which lift the material and shower it down through the hot gas stream.
Working principals:

1. Dying process needs to consume large amount of heat energy. In order to save energy, some materials with high moisture content, suspending liquid and solution which contain solid objects should be mechanically dewatered or heated first, and then they can be dried in a dryer to get dry solids.
