Introduction:

Rotating cylinder drying machine is composed of cylinder body, front roll ring, back roll ring, retaining roller, supporting roller, small gear, roller, a small gear, discharge part, raising plate, reducer, motor, feeding chute, furnace and other parts. According to the heating transfer methods between wet material and heat transfer medium, rotary dryer can be divided into direct heat rotary dryer and indirect heat rotary dryer.

Drum Dryer

Working Principle:

Firstly, the materials that are prepared to be dried are sent by the conveying equipment to the hopper, and the feeding machine inside the hopper will send the materials to the feeding end from which the materials will go into the dryer machine. The drum of the dryer machine slightly inclines upward, and the materials go into the drum from the higher end, and at the same time the heating media will go in the drum from the other end and form backward contact with the materials. Since the drum is slightly slant, the materials will be dried indirectly or directly by the heating media during the moving process, and then the dried materials will be sent from the discharging end. At the same time, inside the drum there is equipped with shoveling plate which will shovel the materials and then put them down. In this process, since the contact surface of the materials and the air flow increases, the drying efficiency will be improved.

Features:

1. It adopts multiple combination lifter devices. The dryer produced by our company has technological innovation of winnowing system in many aspects. The new multi combined lifter device has high thermal efficiency, and the coal consumption is reduced by about 20%.

2. It is suitable for various combustion furnaces: high boiling furnace, coal grinding powder furnace and artificial coal adding stove.

3. The transmission gear adopts a pin column and changeable gear to replace the traditional cast steel gear, which not only saves investment, but also greatly reduces the maintenance cost and maintenance time.

4. The centralized control system can realize the large enterprise microcomputer central monitoring management.
