Rotary dryer is widely used for drying materials in industries like cement, mine, building materials, chemistry, food and fertilizer, Rotary Dryer Manufacturer etc. This rotary drying machine comes with thermocouples on the feeding and discharging device to control the temperature. Thermometers are also adopted so as to better control the working temperature (generally 350-380°) of the rotary drier.

The auto-combustion device provides heat resource for our rotary drier, which adopts down-flow heating method. When the mineral materials are fed into the cylinder, it flows down as a result of gravity. Meanwhile, they are repetitively scattered in the air so that they are in full contact with the hot air. The material is thus dried gradually.

Greenfield Tech Projects  is one of the leading and reputed manufacturing company in India with 3 decades of  experience in the field of drying and processing of Industrial as well as food grade materials. Greenfield Paddle Dryers are  designed and manufactured to that efficiency that it can dry all kinds of sludge by utilizing either steam or heating mantles or oil as an heat source.

Working Principle:

The paddle dryer  for drying or cooling of paste, particle, powder and slurry state of material, perform the process of drying, cooling, heating, sterilizing, reacting and combustion under low temperature. The special stirring and material transferring paddles, makes high heat transferring efficiency, and provide self-cleaning function. The special rectangular shaped paddles does the mixing, stirring and material transferring with high efficiency and self-cleaning function in the heated trough surface.

Rectangular shaped paddles are concentrated on the hollow shaft. Heat media flow through the trough and heats the chamber uniformly. The heat transferring area in the effective volume is very high. The temperature range of heating media is 40 °C to 320 °C. All heat is utilized for to drying the material and there is no heat loss. The surface of rectangular shaped paddles has self-cleaning function. The trough of hollow Paddle dryer is U shaped. To avoid any leakage of material, there’re sealed terminal cover and top cover with the trough. The heat transferring media flow through the rotation connector, jacket’s shell and hollow stirring shaft.

Features:

• The heat consumption of paddle Dryer is low
• The cost of the paddle dryer is low;
• The range of material to be processed is wide;
• The pollution is less: Without any carrying air, very few powder is carried out;
• The operation cost is low;

Steady operation: The material particles fully contact heat transferring surface, because of the special compressing and swell-stirring effect of the paddle. The difference of the temperature, humidity and mixing effect are very small in the different axial area, so to ensure the stability of process.

Working same like Rotary Dryer only travelling method differs. Here material travels in straight direction. Tunnel dryer is used mostly to dry bricks.Rotary Dryer Manufacturer
