Rod mills, how they function

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio ...

Choosing the right boring tool | Cutting Tool Engineering

 · Although heavy-metal bars are more expensive than steel ones, they can be applied at higher length-to-diameter ratios. Whereas steel allows a 4:1 ratio, heavy-metal bars can boost the ratio into the 6:1 or higher range with some speed-and-feed tuning.

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. 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 ...

Ball Mill

Optimum ratio between length L and diameter D, L:D is, usually, accepted in the range 1.56–1.64. The mill productivity also depends on many other factors: physical-chemical properties of feed material, filling of the mill by balls and their sizes, armor surface shape, speed of rotation, milling fineness and timely moving off of ground product.

Understanding Rolling Process in Long Product Rolling Mill …

Mill utilization is a measure of the percentage of time that the mill is rolling steel. The truest measure of performance is as a percentage of calendar time. Factors that influence utilization are maintenance outages, scheduled and unscheduled holiday outages, downtime for cobble clearing, roll and pass changes, excess billet gap, and other factors that create time when a billet is not in the ...
