Roots blower/rotary kiln roots blower
1. Application of Rotary Kiln
Rotary kiln is thermal equipmet for heating and calcination materias.
It is key equipment in the field of Cement & Construction Materials, Nonferrous Metallurgy, Ferrous Metallurgy, Refractory Materials, Chemical Materials, Paper Making and etc.
2. Structural Composition of Rotary Kiln
Rotary Kiln is composed of Cylinder, Gears, Supporting Device, Kiln Liner and Kiln Tail Sealing Equipment, Kiln Head Hood and Combustion.
3. Working Principle of Rotary Kiln
Cylinder is made of high-quality carbon steel plate. As the heated rotating part, Cylinder is supported on the supporting device by tyres. And there is machanical or hydraulic pressure catch-wheel on one or several gears in oder to control the turning of cylinder.
By the gear rings in the middle of cylinder, gears drive the Cylinder to rotating with the speed under technical design requirement.
Because of the need of installation or maintenance, the big size rotary kiln has auxiliary gears, which make cylinder rotates at low speed.
In order to prevent cold air comes into cylinder and the leaking of gas and dust, the reliable kiln tail and head sealing equipment are installed onte he feeding and discharging end.
4. Feature of Rotary Kiln
* Supporting Device:
advanced main shaft structure, automatic temperature measuring device and electrical heating device.
* Catch-wheel:
mechanical wheel or hydraulic thrust wheel
hydraulic thrust wheel is equiped with advanced hydraulic controlling system.
* Gears:
single driving or twin driving
rotating speed is under control of adjustable-speed motor, DC motor, or frequency adjustable-speed motor.
reliable operation, energy-saving and high efficiency.
* Liners for tyres of cylinder
fixed type, adjustable type, or floating type
simple structure, convenient replacement and maintenance without any damage to cylinder
* Sealing device
variety types are available in accordance to different design of rotary kiln;
such as: air cylinder edge sealing, spring edge sealing, graphite block sealing and etc.
* Kiln head hood
stationary type or flexible type
