· Diameter of the electrode contact surface should be slightly larger than the nugget diameter. For example, spot welding two sheets of 1 mm thickness would require an electrode with a contact diameter of 6 mm. In practice, an electrode with a contact diameter of 6 mm is standard for sheet thickness of to mm. This contact diameter of 6 mm conforms to the ISO standard for .
· In 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.

· Approximately 6070 years ago, manual or hydraulically operated grinding machines were in vogue. The quantitative and to a certain extent qualitative needs of that time were less as compared to those prevalent today, hence the wheels used in those days were suitable for the needs of that time. Brief information on the expected degree of quality of a job manufactured by grinding is given in the ...
