Description

Introduction
The rotary dryer made by our company is mainly used in building materials,metallurgy,chemical plant,drying of limestone slag for cement plant,coal powder,slag,claystone,etc.The dryer is formed by rotary body,lifting blade,driving device,supporting device,sealing ring,etc.The dryer has advantages of reasonable structure,high efficiency,low energy consumption and easy operation.

Features
Reliable performance.
High reliability.
Big handling ability.
Little investment and low drying cost.

Working Principle
Rotary dryer consists of gyrorotor,spreading materials plate,transmission device, back-up unit,seal ring and the like.Dried materials are sent hopper by belt conveyor or bucket elevator,then pass through feeding machine of hopper and charging pipe into feeding end. Inclination of charging pipe is bigger than materials’ angle of crater,so that materials can flow into dryer smoothly.Cylinder of drier is rotating cylinder which forms slight slope with horizonal level.Materials are added from relatively higher end,heat-carrying agent enters from low end,it has counter-current contact with materials,heat-carrying agent and materials form cocurrent flow and enter into cylinder.It move the relative bottom end along with cylinder’s rotating materials by gravity.In the process of moving forward wet materials in the cylinder get heat from heat-carrying agent directly or indirectly,which dries the wet materials,and are discharged at the discharging opening through belt conveyor or screw conveyor.
