ROTARY DRYERS

Rotary dryers are one of the most common types of industrial dryer, utilised for large quantities of material with particles of size 10 mm or larger. Typical rotary dryer consist of cylindrical shell made of steel plates slightly inclined (1O to 5O) to horizontal to assist the transportation of the wet material fed for the processing, shell is typically 0.3-5 m in diameter, 5-90 m in length and rotating at 1-5. Rotary dryer shell tube acts as body to transfer the wet feedstock and number of steam heated tubes are placed symmetrically around the perimeter and rotate with it. Wet material is fed into the upper end of dryer and the material travels through it by virtue of rotation and slope of the shell and dried product is picked as the lower end. The feed rate, speed of rotation of shell, the volume of heated air or gases, and their temperature are so regulated such that by the time material reaches to discharge point of rotary dryer it’s accurately dried.

Rotary dryer performs due role in complete drying process, 1) as a conveyor, carrying/ moving material from feed end to discharge end 2) as heating/ drying device. Movement of material within the dryer is influenced by the lifting, cascade action, sliding and bouncing.

Kerone has helped more than hundreds of accurately designed and crafted rotary drying solution varying in size dimension and drying capability. Till dates we have delivered the rotary dryers for approximately for all possible type of industrial application, catering to such large diverse need of industry we have built the rotary system of many types for both batch type rotary drying as well as continuous type rotary drying applications. The key classification of rotary dryers are as follows:

  • Indirect steam-tube dryer
  • Direct Rotary Dryer
  • Direct rotary kiln
  • Indirect rotary calciner

The efficiency is significantly enhanced by insertion of longitudinal plates inside the cylinder these are known as lifting flights. Their purpose of the lifting flights is to lift and shower the solid particles through the gas stream where the air is hottest and minimum moisture is hold. The edge of the lifter can be bend inward or right angle for uniformly processing the material. Typical flight arrangement are as shown above.

    Features of Rotary Dryer:

  • Kerone build the rotary dryer are having robust construction.
  • Kerone provide rotary dryer with various lifter options based material.
  • Kerone provides the option of either co-current or counter-current air circulating rotary dryer.
  • Rotary dryer designed by Kerone can be utilised for higher temperature drying.
  • We design and build rotary dryer with wide range of size and dimensions to handle wide range of material.
  • We provide fully automated rotary dryers by means of PLC/SCADA systems.
  • Rotary dryers are suitable of continuous drying operation.
  • This type of dryer provide relatively longer residence time.

    Application of Rotary Dryer:

    Practically rotary dryers can be used for any in any industry for drying such as:

  • Food and Dairy Industry.
  • Agriculture and Animal Feeds.
  • Chemical and Pharmaceutical Industry.
  • Ceramic Industry.
  • Sand Industry..
  • Rubber Industry.
  • Foundry Industry.
  • This type of dryer provide relatively longer residence time.

Some of the common materials those are treated within the Rotary dryers are as follows:
