Rotary Dryer

Introduction:Rotary Dryer is also called rotary drier. Rotary Dryer(Drum Dryer) is widely used for drying materials in the industries of cemet, mine, contruction, chemical, food, compoud fertilizer, etc. If you want to buy rotary dryer or want to know price of rotary dryer, please contact us.

Rotary Dryer Overview

Rotary Dryer Instruction:

Dryer machine, which is also known as rotary dryer, limestone dryer, or cement rotating dryer, is the key equipment to dry different materials with humidity or granularity in various fields. Rotary Dryer(Drum Dryer) is widely used for drying materials in the industries of cemet, mine, contruction, chemical, food, compoud fertilizer, etc. Feeding and discharging unit is installed with thermocouple to control drier temperature. The temperature change of drier's feeding end can be indicated by the thermometer to control the inner drier temperature ( generally 250-350o).

Performance Features of Rotary Dryer:

The machine mainly consists of rotary machine, raising plate, transmission device, supporting device and seal rings and other components. The dry machines in our company use the new-type raising plate, which has the functions of guiding, even flow, raising materials etc. The raising plate can make the materials be distributed uniformly to the cross profile in the dryer machine. The material curtain is at the state of thin, even and complete, with completely touching with the hot air flow to reach the purpose of making full use of the heat energy. The consumption of coal and electricity of the dryer in our company can be lower 10% to 15% than the normal dryers, with the production ratio higher than 10% to 15%.

Rotary Dryer Structure:

Rotary Dryer machine is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap. The accessories which are not in the the scope of this machine include firebox, feeding and discharging equipment, dust catcher, etc.

Rotary Dryer working principle:

Rotary Dryer adopts direct flow type of heating with heat soure from firing unit. The material to be dried is pushed back immindiately by spiral board when enters the shell from feeding tank and feeding chute. Because the drier is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering.
