Variables in Ball Mill Operation | Paul O. Abbe®

The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results. In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time.

Often, minor moisture migration problems can result in severe spoilage. Check grain often for signs of moisture migration. Look for crusting, wet, slimy grain, ice or frost accumulation, and/or heating. Check for condensation or frost on the underside of roof surfaces, hatches, and vents on cold, crisp days before the sun warms the roof.

What Is A Wet Scrubber? - CECO Environmental

Wet Scrubbing of Particulate Matter. Wet scrubbers can remove particulate matter by capturing them in liquid droplets. The droplets are then collected, with the liquid dissolving or absorbing the pollutant gases. Any droplets that are in the scrubber inlet gas must be separated from the outlet gas stream using a mist eliminator.
