Drum Dryer is a kind of dryer, which belongs to building materials equipment. The center of the drum dryer can avoid increasing the dispersing mechanism. The wet material entering the drum body is repeatedly copied and thrown by the sheet on the wall of the drum. During the falling process, the dispersing device breaks up into fine particles, which greatly increases the specific area and fully contacts and dries with the hot air.

Highlight Advantages

The drum dryer adopts a new type of multi-combination lifting device, which overcomes the "wind tunnel" phenomenon of the traditional dryer, has high thermal efficiency and effectively reduces the coal consumption by about 20%.

Our company specially designed the retaining wheel structure of the drum dryer, which greatly reduced the horizontal thrust caused by the inclined work of the equipment. Strong anti-overload ability, smooth operation of the cylinder, high reliability.

No air leakage phenomenon, completely solved the sealing difficulties, can be installed in two hours; in addition, the thermal efficiency of equipment is up to 80% (the traditional single drum dryer thermal efficiency is only 32%) and increased by 48%.

Roller dryer has strong adaptability to materials, can dry various materials, and the operation of the equipment is simple and reliable, so the dryer equipment has been widely used.
