Our company is recognized as the astonishing manufacturer and exporter of Rotary Dryers & Coolers, used for cooling of free flowing materials by introducing cooling media directly onto the processing material. Various types of fuels are used for firing these dryers and are ideally designed for rough applications. Our Rotary Dryers & Coolers are available in number of configurations and specifications as per the requirement of the patrons.
- Low power consumption
- Effective cooling
- Low maintenance cost
An industrial Rotary Cooler or Dryer is an equipment used for cooling / drying of free flowing materials, with the help of cooling / drying media, placed directly onto the processing materials. Dryer rotates and experiences the material to be cooled or dried, and the material is raised up through a series of interior wall inner fins lining of the dryer. There are mainly two types of the dryer including Direct Heaters/Coolers and Indirect Heaters/Coolers. These rotary coolers or dryers are incorporated with a rotating shell, which plays the role of stirrer as well as conveying device.
The material is cooled or dried in direct contact with cooling or drying media, in direct coolers / heaters. There are two stationary hood, one is stationary inlet hood at one end to admit cooling or drying media and another is discharge hood to taken out the media at the other end. Also, the feed process is achieved through a proper feeding mechanism like a simple chute or screw feeder. Specially designed material showering mechanism is provided to the rotating shell. Shell rotating and inclination speed serve forward motion of the material to discharge end, creating needed act time. The stationary hood is well integrated with suitable equipment like rotary valve / flap valve / screw conveyor etc.
In indirect coolers, the material to be dried does not experience any direct interaction with the drying media. With proper drive arrangement, the dryer or cooler comprises of an assembly of two concentric revolving shells, effectively based on rollers and tyre stations. A stationary inlet feed hood is used for feeding with suitable feeding mechanism such as screw feeder or flap valve. The drying media is fed through a inner shell, and move towards the discharge end, it then again returns to feed-end with the help of a specially designed return gas section, placed on the outer-shell interior. The inner shell radial lifters are specifically designed for feed material showering. Forward move of the material towards discharge-end is attained with shell inclination and rotating speed.
General Design Features:
These industrial coolers / dryers are fabricated by using steel and are of large rotating cylindrical tube, either backed by solid steel pillars / beams, or supporting rollers. Suitable drive arrangement of rotating shell comprises girth gear and pinion, which are provided with a gear reducer, coupled to a suitable rating motor. Also, these are provided with separate pollution control equipments like bag filters, wet scrubbers / cyclones.
Several fuel types and forms are used for firing of the dryers. Gaseous, liquids and solid fuels can be applicable.
