Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.

Vertimills® are primarily selected because of the operational cost savings they have over other grinding mills. The total cost of ownership for a Vertimill® is almost always significantly less than a traditional horizontal ball mill solution. The Vertimills® advantages include:
Extra Long Reach Ball Nose End Mills. These mills are are often used in the mold industry where you need to reach into a pocket to mill and not hit the side wall. The have a stub lenth flute and a necked down diameter between the cutting edge and the shank. They have two or four cutting edges, and a center cutting full radius or "ball" on the end.
Vertimills are globally recognized as energy efficient grinding machines and have been proven to grind more efficiently than ball mills with feeds as coarse as 6 mm to products finer than 20 microns.
Rather than using a lab scale Vertimill, which suffers from scaling problems, this test utilises a lab scale ball mill that is smaller than in the Bond and Levin tests, and uses 19 mm media (typical of industrial Vertimills), to carry out a series of batch grinds on the feed material at different energy inputs. This allows for better ...

Its vertical configuration allows for large throughputs while maintaining a small footprint in your circuit. The VERTIMILL® can bring up to 40% savings in energy consumption in some cases, and helps in reaching excellent recovery rates by producing a sharper particle distribution.
A new general formula to predict the specific energy of grinding in ball mills and vertimills. Pechea. Published in Proceedings of the IMPC2020 Congress, SAIMM. ABSTRACT. Since 1952, Bond's equation has been used as a standard to predict the specific energy of grinding for a given duty. The Bond's equation considers that the exponent is ...
Perhaps, historical failures due to poor SAG/ball mill designs and operation is what is fueling the clarion call by some for the demise of these grinding equipment . SAG mills and Ball mills will be energy efficient if correctly designed and correctly operated. A paradigm shift in the design and operation of SAG/ball mills is much needed.
