Find the shaft power | ball mill length when the volume load percentage is 8, the %critical speed is 10, the bulk density is 3. the mill length is 14 and the mill internal diameter is 16. This implies that; J = Volume Load Percentage = 8 V cr = % Critical Speed = 10 sg = Bulk Density = 3 L = Mill Length = 14 D = Mill Internal Diameter = 16
In this work, several FeCr alloys have been designed for the ball mill liner working in weakly alkaline slurry with Timagnetite. To work under wet grinding condition, the alloys used for ball mill liners were considered to be phase structures with high hardness, toughness and corrosion resistance [11, 26, 27].

Highcarbon CrMo and lowcarbon CrMo steels are common alloys to produce SAG mill shell liners [1719]. In the present research, the wear behavior of SAG mill shell liners of Chadormalu iron ore complex has been investigated to obtain the proper solutions to improve lifetime of liners from the metallurgical point of view.
Critical Speed and a Grinding Ball. For the ball mill to work properly, it must reach critical speed. This is the speed at which the grinding balls start to spin along the ball mills' interior walls. If the ball mill does not reach critical speed, the grinding balls will stay at the bottom. They won't be able to grind the material properly.
