At Cadia the first Vertmill sizing was based on a Bond Wi of 16 kwh/t ten years ago the ore BWi is now 18.5 kwh/t after ten years so if you turn up at site and compare what the Ball mill or Vertimill or SAG is doing now with what it was sized based on ten years then for sure they are all under-performing 15%.

How to Save Time and Money by Bringing Your Tool ...

But an end mill that cuts a shape to a certain size can be reground. As the end mill gets smaller, the settings can be adjusted so it cuts more or less material. It also might not be practical to regrind a smaller tool — say a 5- or 6-millimeter carbide end mill that might become weakened with the loss of minimal material.

Scale Up in Sizing for Grinding Mills Scale-up criterion is the net specific power consumption, i.e. the power consumed by the mill rotor itself minus all mechanical and electrical losses divided by the feed rate of solids. For the full scale mill, specific power is multiplied by the feed rate to get the net mill power.

Why we should regrind our tools ? – Trading Cutting Tools

We recommend regrinding HSS drills when the value of "W" reaches 0.4mm for small drills and 0.7mm for larger drills. For carbide drills, regrind when W is 0.2-0.4mm. When regrinding a drill, all visible wear must be removed. Back to top Regrinding Method: In order to obtain the best results, drills should be reground as if they were brand new.
