Jul 01 2003· This phenomenon occurs more easily with lighter and smaller grinding media and also with higher product flow rates and viscosities Hydraulic packing can occur to a small degree causing increased mill wear at the discharge end and higher milling temperatures or can be severe resulting in immediate pressure buildup followed by mill shutdown
the wear of grinding media with hardness 350 – 400 Brinell is for big balls of 80 – 200 gt 10 – 25 gkWh and for small balls and cylpebs of 35 – 120 gt 3 – 10 gkWh The wear is much reduced for grinding media chromium alloyed steel with hardness 600 – 700
Smaller media has more contact with the parts'' surface area than larger materials and produces a smoother more attractive surface Production times are longer for small media polishing because smaller finishing material requires gentler processing Larger media produces a rougher surface but lends itself to more aggressive grinding
