Air Supply Of Industrial Rotary Kilns Heavy Duty Backward Centrifugal Fan
Introduction
The 5-10 series ventilator Heavy Duty Backward Centrifugal Fan is a high efficiency and energy saving product developed by our company, which is used for ventilation and exhaust system of smelting, chemical, medicine and dust removal production lines.
In the coal-fired boiler system, the ventilation and induce draft systems of various boilers with evaporation capacity of 20 tons/hour to 800 tons/hour can be configured.
The Heavy Duty Backward Centrifugal Fan bearing housing uses labyrinth mechanical seal, unique anti-leakage design inside, vent hole at the top, and sealing grease at the joint, completely eliminating the possibility of oil leakage in the bearing hosing.

Advantages and Features
1.Air Supply Of Industrial Rotary Kilns Heavy Duty Backward Centrifugal Fan can output higher outlet pressure and provide more gas flow at the same time, low noise. Stable operation at higher media temperatures.
2. The Air Supply Of Industrial Rotary Kilns Heavy Duty Backward Centrifugal Fan speed can be flexibly set by matching different belt pulley diameters to make the fan run at the highest efficiency point and reduce energy waste.
3. Motor slide guide can be provided for convenient belt tensioning to reduce energy loss caused by belt slack.
4. The Centrifugal Fan bearing housing is reserved for the installation position of temperature and vibration sensors, which can facilitate the installation of fan operation monitoring device.
5. Use liquid lubricating oil. It is not necessary to open the bearing housing to replace and fill the lubricating oil. The bearing housing is provided with an observation window for easy observation of the quality and stock of the lubricating oil.
