Message: | The material inside the rotary dryer has heat exchange with the high temperature flue gas through shell rotating and material lifting by lifter. The rotary dryer has many good characters like: high efficiency, big capacity, high running rate, saving energy, easy for maintenance, long working life. Variety angle of the lifter will increase the heating exchange rate and short drying time. That is widely used for drying lay, slag, fly ash & etc.
After the welding of bases for supporting devices of supporting roller and catching roller, vibration aging treatment should be applied for remove the welding stress. Then, use vertical lathe and boring-milling machine for integration fabrication. This process can guarantee the requirement of fabrication precision and dimension & location tolerance. Installation accuracy of rotary kiln is obviously improved.
Rotary dryer’s advantages as follows:
1. Variety angle of the lifter will increase the heating exchange rate and short drying time.
2. High drying efficiency, big capacity, high running rate
3.Operation stable, easy maintenance
Rotary dryer is mainly compose of driving device, supporting roller, thrust roller, cylinder, kiln inlet, kiln outlet and sealing device.
1. 2-3 supporting points can guarantee the contacting surface between supporting roller and tyre is paralleled with axis line of cylinder during installation.
2. Supporting device is antifriction bearing (occasionally uses slide bearing). This design has simplified the supporting device of supporting roller, and reduced the useless power loss during operation. It has the features like easy operation and maintenance.
