#### Tube and pipe basics: How to achieve the perfect bend

For this system, the tube feeds between an upper and lower roll, while on either side two adjustable guides move to produce the desired bend angle. Many use roll bending to produce spirals. If a workpiece has a one-diameter pitch and a large radius, the operator can lift the tube after one revolution to produce a continuous coil.

#### Calculate and Select Ball Mill Ball Size for Optimum Grinding

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.
