• ### DEM modeling of ball mills with experimental validation

· Discrete element method simulations of a 1 5-scale laboratory ball mill are presented in this paper to study the influence of the contact parameters on the charge motion and the power draw. The position density limit is introduced as an efficient mathematical tool to describe and to compare the macroscopic charge motion in different scenarios i.a. with different values of the contact parameters.

The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell s inside surface. This is the rotational speed where balls will not fall away from the mill s shell. Result #1 This mill would need to spin at RPM to be at 100 critical speed. Result #2 This mill s

· CNC Milling Toolpaths at a Glance. CNC milling toolpaths are typically categorized as 2D 3D 4-axis and 5-axis. However the term 2D is a bit misleading since this toolpath uses the Z-axis to position a tool for depth. For example in the image below we have a prismatic part whose features all reside at various heights on the XY plane.

· In the case of the overflow mill in order that the product shall overflow through the hollow trunnion it is necessary that the general level of the powder surface must correspond to about a 45-50 filling of the mill. Then when the ball filling is about 45-50 the overflow mill corresponds to a batch mill and so the power input should be directly calculable from the present work.
