Product Introduction:
A rotary kiln drum dryer is an internal heating continuous drying equipment with conduction. The rotating drum, through its lower feed trough, adheres to a thick layer of material film. Heat is transported to the inner wall of the drum via pipes, conducting to the outer wall of the drum, and then to the material film, causing the moisture in the film to evaporate and dehydrate, thereby drying the moisture-containing material.
During the operation of the rotary kiln drum dryer, attention should be given to the maintenance and care of the equipment. Proper maintenance and care can extend the life of the kiln shell, shell ring, thrust roller, idler roller, shaft, and bearing; reduce the damage to the gear ring, drive gears, and controller; prevent overheating in the kiln shell gaps and the kiln drum; increase the lifespan of the fire-resistant lining material; and mitigate the damage to the rotary kiln caused by mechanical imbalance.
Main Characteristics of the rotary kiln drum dryer equipment:
1.Drying materials through thermal conduction, with heat efficiency typically reaching80%Above
2.Easily scalable, capable of being expanded by adding fins to the heating tube, achieving a larger heating surface area.2000Over 1 square meter, highly suitable for use in large-scale chemical, mining, coal drying industries, etc.
3.Can be dried under atmospheric pressure or in a closed-loop system, capable of recycling solvents, and is particularly suitable for drying flammable, explosive, and oxidizable materials.
4.During atmospheric pressure drying, hot air is used solely to carry away moisture, with minimal volume and low dust carryover, resulting in reduced load on the post-treatment equipment.
5.Simple to operate, flexible, easy for long-term stable operation, and easy to automate.
