Heavy Duty Long Lifetime Cement Fan Anti Abrasive Forward
Introduction
The 5-12 series centrifugal fan is an enhanced version of the 5-11 series medium pressure centrifugal fan.
Motor is carefully matched to the fan load, protection level IP54, and insulation class F. Motor ball bearings are used and lubricated. Motor and drives are isolated from the air stream to avoid grease or dirt accumulation.
Detail introduction
Fan shaft shall be heat treated through soaking furnace to the hardness level between HB250-280, and the maximum load should be 35% higher than the maximum fan operational speed. The shaft shall have shaft cover. It shall use 40 Cr steel when it is operated under 250.C and 35 CrMo shall be used when operating between 251.C - 450 .C. Cylindrical bearing box shall be used to support the fan shaft.
