A tracer pulse is injected at the mill inlet and the concentration of the tracer is measured at the mill outlet. Although the RTD data clearly indicate that finite axial backmixing takes places in many continuous opencircuit mills [18,2325], many researchers assumed idealized mixing regimes,, perfect mixing [2629] or plug flow [7,12,30,31], for the sake of simplicity in their ...

As for why I don't turn it, well I have 3mm ball endmills in stock but I don't have a grooving tool to cut this in stock. You can see the groove has an undercut so I need to come in at that angle with a 3mm ball mill to get my feature made. Thanks for any suggestions.

A mill is a machine that is used to break down solid materials into smaller pieces by cutting, grinding, or crushing. The process of milling includes the use of force that acts on a material to tear it apart and reduce its size. Milling improves the performance of ingredients, and the products made from them.

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell Cmodel or equation to get the RPM that corresponds to 75% for that mill diameter.

When discussing 5axis machining, it is important to differentiate the 3+2 axis and simultaneous 5axis machining differences. Generally, a 5axis CNC mill will have three linear axes: X, Y, and Z. They also will have two rotating axes, either AB, AC, or BC. The rotating axis corresponds to the linear axis.
