Drying Machine

Brief Introduction

Rotary Tube Drying Machine is widely used in building materials, metallurgy, chemical industry and cement industry to dry the stuff such as limestone, coal powder, slag and clay. It mainly consists of revolution body, lifting stuff plate, driving device,supporting device and seal ring. It has the advantages of reasonable structure, fine manufacture operation.

Main Structure

Rotary Tube Drying Machine mainly consists of barrel, front roller circle, back roller circle, gear, block roller(not applicable to the small size drying mahcines), drag roller, pinion, discharging part, raise board, reduction gears and so on.

Working Principle

During the drying process of the materials: the wet materials are conveyed to the hopper through belt conveyor or bucket elevator, and then enter into the feed end through the feeding pipeline of the charging machine. The inclination of the feeding pipeline should grater than the natural inclination of the materials in order to the materials flow into the drying machine smoothly. The drum of the Rotary Tube Drying Machine is a rotating cylinder which has a certain inclination with the level. Materials are added from the higher end and heat-carrying agent is entered into from the lower end. They could have the countercurrent contact and also could flow into the barrel together. With the rotating of the drum, materials will move toward to the lower end under the influence of the action of gravity. During the moving forward process, the wet materials obtain the hot of the heat-carrying agent directly or indirectly. This could make the wet materials become dry and conveyed by the belt conveyor or the screw conveyor in the discharge end.
