Calculate and Select Ball Mill Ball Size for Optimum Grinding

20191116&ensp·&enspIn Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

How to Calculate Wheel Life in a CreepFeed Grinding

20181024&ensp·&enspFor noncontinuousdress creepfeed grinding, the calculation is straightforward. For continuous dressing, the calculation has more steps, but in either case, it is possible to manage the cost of grinding by predicting the life of the wheel. The formula to calculate the wheel wear is:

20191030&ensp·&enspTungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives

8 Principles of Centerless Grinding

A downside of centerless grinding is you can't have as many multiple axes operating on the workpieces. However, there are many parts where the process addresses the limitations of machining in terms of dimensions, materials, and surface finishes. That's why we like to say that where machining ends, the centerless grinding process begins.
