### How Mill Load/Charge is EstimatedGrinding

Modern mills operate with load cells and mill optimizer s which synchronize the mill weight power draw ore feed and weight with density control. Where optimizers are not used the rule of thumb for a overflow ball mill is a ball load up to about 12 inches below the trunnion discharge- this allows bed expansion by the slurry filling the voids Ball Mill Simulation and Analysis. This video shows the inside of a Semi Autogenous Grinding (SAG) mill a key machine for grinding crushed materials in mining. Optimize your SAG Mill operation using EDEM tools for analyzing the motion of rocks and balls power consumption wear and ball particle distribution through time.

### Understanding Chip Formation in High Performance End Mills

Destiny end mills also form a manageable "6" and "9" shaped chip by traveling down through the gullet to the core diameter of the end mill. However we have developed a rake face geometry that enables the material to curl in the outer rake face as you can see by the red arrow above. By doing this we create much less friction (and HEAT) in the tool which translates to longer tool life. Wiki says "A ball mill is a type of grinder used to grind materials into extremely fine powder for use in paints pyrotechnics and ceramics." Many instructables refer to United Nuclear Ball Mills. Their small ball mill cost between 70 and 80 dollars. For no more than 30 and in 5 minute you can build a ball mill of appreciable performance.
