Piyali Group Rotary Dryers

Drying and Evaporation Plants

Application of Rotary dryer :
It is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotating dryer can be used for drying many kinds of materials and with convenient and reliable operation; therefore, it has been widely used.

Working Principle of Rotary dryer :

After wet material is put into the hopper, the stove generates hot wind. Then wet sawdust is sucked into the pipes by the exhaust blower(fan) , flowing and go though the curving pipes and buffer(drying chamber) of dryer, thus the wet material is dried, and the dried material is discharged from the outlet with air lock.

This type of dryer is suitable for drying heat sensitive material which is light and small like sawdust, rice shell, milled stalks etc. General Wet material can be dried in a few minutes. Compared with rotary dryer, it has the advantages of low energy comsumption, low cost.

Rotary dryer is mainly consist of rotary body, raw material feeding plate, driving and supporting device, etc.The operation principle of rotary dryer: the raw material plate which is arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder. Then water will be separated from the materials by hot air-flow and changed into vapour to be discharged into the atmosphere. Then the materials would be dryed.Rotary dryer is used to dry slag, clay, limestone, It is mainly used for cement, chemical, metallurgical, building materials industries. Its advantages are as follows: high dry capacity, smooth rotation, low energy consumption, easy operation, high output and so on.Rotary Dryer is used for drying materials with a certain humidity or granularityin milling of ores, building materials, metallurgy and chemical industry.Gyro drying machinery has a strong adaptability of materials and it can dry various materials. The operation is very simple and liable. For this reason, it isused widely.Indirect heat transfer Rotary dryer is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotating dryer can be used for drying many kinds of materials and with convenient and reliable operation; therefore, it has been widely used.

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.Compact structure, 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.

3. Suitable shim between tire and shell will ensure the tire ring on the shell tightly to increase the shell strength.

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

Radial direction contacting type sealing device is adopted at kiln inlet and outlet. They are perfect suitable for dimension tolerance of cylinder and skewing movement of cylinder. This sealing device’s feature is good performance, longer working life and easy for replacement.
