  • Introduction
  • Features
  • Technical Data

The material inside the rotary dryerhas heat exchange with the high temperature flue gas through shell rotating andmaterial lifting by lifter. The rotary dryer has many good characters like:high efficiency, big capacity, high running rate, saving energy, easy formaintenance, long working life. Variety angle of the lifter will increase theheating exchange rate and short drying time. That is widely used for dryinglay, slag, fly ash & etc.

After the welding of bases forsupporting devices of supporting roller and catching roller, vibration agingtreatment should be applied for remove the welding stress. Then, use verticallathe and boring-milling machine for integration fabrication. This process canguarantee the requirement of fabrication precision and dimension & locationtolerance. Installation accuracy of rotary kiln is obviously improved.

Rotary dryer is mainly compose ofdriving device, supporting roller, thrust roller, cylinder, kiln inlet, kilnoutlet and sealing device.

1. 2-3 supporting points canguarantee the contacting surface between supporting roller and tyre isparalleled with axis line of cylinder during installation.

2. Supporting device is antifrictionbearing (occasionally uses slide bearing). This design has simplified thesupporting device of supporting roller, and reduced the useless power lossduring operation. It has the features like easy operation and maintenance.

3. Suitable shim between tire andshell will ensure the tire ring on the shell tightly to increase the shellstrength.

4. The main driving system uses newtype AC variable frequency technology. Compared with electromagnetic speedcontrol and DC speed control, that can save energy, have large range & highprecision of speed regulation, high efficiency and running smoothly.

Radial direction contacting typesealing device is adopted at kiln inlet and outlet. They are perfect suitablefor dimension tolerance of cylinder and skewing movement of cylinder. Thissealing devices feature is good performance, longer working life and easyfor replacement.



Rotary dryer's advantages as follows:

1. Variety angle of the lifter willincrease the heating exchange rate and short drying time.

2. High drying efficiency, bigcapacity, high running rate

3. Compact structure, operationstable, easy maintenance
