Ball mill

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

How to Determine Cutting Speeds for Machining Tools

The outside of the end mill/tire will be zipping past the surface below at 1,320 SFM (surface feet per minute). Okay, but how fast is the thing actually rotating, or its rpm (revolutions per minute)? Since machining centers don’t have gas pedals (nor gages that announce the current cutting speed), spindle rpm is the value we have to plug into the CNC program.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Operating Speed Of Ball Mill

Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size - mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media.
