Rotary Drum Drying Machine

Introduction:

It also named rotary drum drier, it is a heating and drying device for material. Were widely used in cement, mining, building materials, chemical industry, drying coal, limestone, grain, sand, clay and other materials.

The main part of the drum dryer for a slightly sloping rotating cylinder.cylinder rotating by gear transmission, speed is commonly 2 ~ 6r/min, the gradient of cylinder related to its length, usually between 1 ° ~ 5 ° between. Material were feeding into from the higher side of the drum, and fully-contact with hot air, along with the rotating cylinder, materials was dry and eduction under the force of gravity flow to the lower end . As the dryer were working under the negative pressure conditions,so feeding and discharging end all use sealing device to avoid air leakage.

Rotary drum dryer working principle

Rotary dryer is a revolving round drum with a small slope.atrial from the high side into the pipe and heat-carrying agent into is from the low end,counter-current contact with material,also material can flow into the drum pipe with heat-carrying agent.

Along with rotate of the round drum materials run to the bottom of the end by gravity .when.the wet material moving forward in the pipe,can get the heat from the heat-carrying agent directly or indirectly to make the material dry,then discharge the material by the belt conveyor or screw conveyor.

Rotary Drying Machine Feature:

1.The raising material plate with reasonable distribution and angle,

2.with reliable performance,that high efficiency on heat power, Uniform on dry.,less time on cleaning machine,.convenient in maintenance .

3.Machine adopted Tug-aligning type structure,tug working well with the tyre-roller,greatly reduce the wear and power consumption.

4.This equipment specialized in the design of catch wheel structure, and greatly reduce the horizontal thrust which cause for the equipment tilt to work

5.Strong resistance to overload , operating smoothly and high reliability

6.With high heat resisting ,can use high temperature and heat wind for rapid drying,strong extensible ability.

7.The design of drum dryer considering the production margin, even a small increase in production, and do not need to replace equipment.

8.Round drum dryer with large capacity, less fuel consumption ,Low dry cost .
