how feed rate affects primary ball mill performance

Speed and feed for surface milling

Speed and feed for surface milling

Sep 24, 2012· Through my experience's, I've found that sticking to the manufacturer's sfpm and cranking up the feed is normally the way to go. I use a lot of 1/8 ball nose end mills 12k rpm and upwards of 150 200 ipm. Since the finish shouldn't be taking a lot of material off, you still need to produce a chip. Hence the high feedrates.

Effect of Slurry Solids Concentration and Ball Loading on ...

The residence time distribution (RTD) of mineral slurry and slurry holdup volume in an industrial ball mill has been successfully studies using tracer tests. Six different conditions of solids concentration and three levels of ball loading were assessed. The effects of the slurry solids concentration and the ball loading on the mean residence time of slurry were clearly depicted in the results.

Apr 01, 2008· Feed rate affects surface finish as well. The pass of each cutting edge as the tool advances creates a "cusp" of its own. Therefore, if a smooth surface is the goal, then the same value calculated as the limit of the radial depth should also be applied as the upper limit on the inchpertooth feed rate of the tool.
