Kerone brings over 50 years of experience in designing high-performance rotary dryers for a wide range of industrial and commercial applications. Built with advanced heat transfer mechanisms and automated controls, Kerone’s rotary dryers are engineered to deliver optimal drying performance while maintaining product integrity.
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 dryers perform a dual role in the complete drying process. Firstly, they act as a conveyor, carrying and moving material from the feed end to the discharge end. Secondly, they function as an efficient heating and drying device. The movement of material inside the dryer is influenced by lifting, cascading action, sliding, and bouncing, which ensures proper exposure of the material to the drying medium.
Kerone has successfully delivered hundreds of accurately designed and precisely crafted rotary drying solutions in various sizes, dimensions, and drying capacities. We have supplied rotary dryers for almost every type of industrial application. To cater to diverse industry needs, we manufacture both batch-type rotary dryers and continuous-type rotary drying systems. The key classifications of rotary dryers are as follows:
The efficiency of a rotary dryer is significantly enhanced by the insertion of longitudinal plates inside the cylinder, known as lifting flights. These flights lift and shower the solid particles through the gas stream where the air temperature is highest and moisture content is lowest. The edge of the lifter can be bent inward or at a right angle to ensure uniform processing of the material. Typical flight arrangements are designed based on material characteristics and drying requirements.
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:
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 below.
