Rotary Dryers

The most popular types of industrial dryer is rotary dryers it is used for a large amount of materials containing a particle size 10 mm and more. The typical rotary dryers are composed of steel plate cylinder which inclines approximately 10 to 45 degree to the horizontal direction for the transport of the wet substance in feed. The wet-feed is transferred in the body of the rotary dryers–shell-tube, while a number of the steam heated tubes arranged symmetrically on the periphery rotate along with this one.

The material travels through the tubular shell which slopes downwards and rotates towards its lower end where it produces dry product. This is achieved through controlling the feed rate, the speed of rotation of shell, the volume of heated air or gases, as well as their temperature in such a manner that by the time material reaches to discharge point of drying unit it gets perfectly dried.

Rotary dryers performs due role in complete drying process,

• As a conveyor, carrying/ moving material from feed end to discharge end
• As heating/ drying device.
• The dryer’s material movement is affected by lifting, sliding, bouncing, and cascade action.

More than hundreds of accurately designed and crafted rotary drying solutions, varying in size dimensions and drying capacity have been provided by kerone. To date we have supplied a vast variety of rotary dryers suited to any possible type of industrial application meeting the huge diversity of requirements of industries we’ve designed the rotary drying systems of numerous sorts intended for both batch-typed and continuous-type applications in drying processes.

The following is a key classification of rotary dryers:

1. Direct Rotary Dryer
2. Direct rotary kiln
3. Indirect steam-tube dryer
4. Indirect rotary calciner

Inserting longitudinal plates—also referred to as lifting flights—inside the cylinder greatly increases efficiency. Lifting flights are intended to raise and shower solid particles through the gas stream, which contains the warmest air and least amount of moisture. For even material processing, the lifter’s edge can be bent inward or at a right angle.
