Sep 06, 2017 During mill operation roller surfaces wear down, which results in a higher dynamic load, peaks which exceed the nominal torque and, in general, an instable mill operation and lower performance. In many instances, bearing failures at the rolls are caused by excessive dynamics in the grinding process.

Nov 07, 2018 Dynamic spindle-speed and feed-rate for ball end mill 3D finishing Finishing 3D surfaces with a 3-axis machine and a ball end-mill can be challenging. In a single op, you can have the ball engaged near the tip where the SFM is much lower, and other times engaged near the side where it behaves more like a straight endmill -- and anywhere in between.
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
dynamic response of foundations Bhatia, 2006. Based on the scientific investigations carried out in the last few decades it has been established that it is not enough to base the design only on the vertical loads multiplied by a dynamic factor, even if this factor introduces a dynamic load many times greater than the original one.
