The primary air input to a ball tube mill performs a dual function. It is used for drying and as the fuel transport medium, and by regulating it the mill output is regulated. Governed by the pulverized fuel outlet temperature requirement, the cold air and hot air dampers are regulated to achieve the correct primary air temperature.
The risk of explosions or fires can be extreme when the coal mill inlet temperature increases to more than 600°F or the outlet temperature is more than 200°F. Velocity in Ducts and Burner Pipes. Fuel efficiency would tend to dictate that the airflow should be varied as the coal feed rate varies.
A) Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill volume (inside liners). B) Overflow Discharge Mills operating at low ball fillings – slurry may accumulate on top of the ball charge; causing, the Total Charge Filling Level to be ...
Ball mill shells are often furnished with two manholes. Ball mills – with small balls or cylpebs – can produce the finest product of all tumbling mills. 80% minus 74 microns is a normal requirement from the concentrators. The CRRK series of wet grinding ball mills are tabulated below. PEBBLE MILLS
Figure 4 compares a conventional vertical table type pulverizer with a ball tube mill pulverizing system with crusher dryer. The table type pulverizer allows high temperature air to reach the coal charge. The ball mill system with crusher dryer normally reduces the inlet temperature to less than the auto ignition point of the coal charge.
