Feb 16, 2021The model of coal mill induced draft fan of a company is W47315NO19F, the air volume is 100000m/h, the wind pressure is 2200Pa, the rated current is 28A, the design speed is 960r/min, the motor power is 250kW, and the actual operating current is 19 20A. The fan is generally stable at the beginning of operation, and the vibration of the fan bearing house is generally about 0.6mm/s.
The mill system consists of coal feeders, crusher dryers, standalone centrifugal static classifiers and a ball tube mill. coal from the feeders is mixed with hot primary air and then fed to crusher dryers. After primary crushing and initial drying with the crushers, the crushed coal is fed into the mill
Our 17 x 34 wind tunnel exceeds all EPA specifications for calibrating probes per EPA Method 2. The ASC tunnel is also large enough to calibrate probes with assemblies such as sampling nozzles, PM 2.5 cyclones, and PM 10 cyclones. The tunnel has a velocity range up to 150 feet per second. The 36 diameter axial fan is powered with a 125 HP

The BTM is a lowspeed mill that primarily grinds coal by impact and attrition. The VRM is a medium speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
