Coal dryer can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste, and clay stone. They are widely used in building materials, metallurgy, and chemical industry. The dryer can use coal, gas, electricity, oil and wind power to heat the dryer machine.

Our products advantages of Coal dryer:

1. High drying efficiency, big capacity, high running rate

2. Compact structure, operation stable, easy maintenance

Coal 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.
