The Ball Mills are on a schedule of 4-monthly overhaul. The main job is the repair or replacement of the lifters and liners, but other work is carried out on the mill to ensure its reliable operation over the following 4 months. In addition, preventive maintenance is carried out on other units in the stream (e.g. the conveyors).

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, allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter).

A ball mill efficiently operated performs a wide variety of services. In small milling plants, where simplicity is most essential, it is not economical to use more than single stage crushing, because the Steel-Head Ball or Rod Mill will take up to 2″ feed and grind it to the desired fineness.
Mechanical alloying is a solid-state powder processing technique that involves repeated cold welding, fracturing, and rewelding of powder particles in a high-energy ball mill. Originally developed about 50 years ago to produce oxide-dispersion-strengthened Ni- and Fe-based superalloys for aerospace and high temperature applications, it is now recognized as an …
The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44-µm (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as …

Industries ball mill their glazes, engobes and even bodies as standard practice. Yet few potters even have a ball mill or know what one is. Article. A true ball mill is a porcelain jar partly filled with spherical or rounded cylindrical porcelain balls. Industrial versions are made of metal and have porcelain linings.
Ball mill is typically used to grind and/or blend materials and it can be done wet or dry. It can be used to mix ceramic powders, disperse particles in solvents, homogenize ceramic slurries, etc. Ball mills operate by rotating plastic jars around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
Solid sweep on right angle path. I want to model a cut with a ball end mill. The path is a U shape with two 90 degree angles, which is what the machined tool path will look like when the tool is moved in the X ais, then Y axis, then in the X axis again. I can do a swept cut using a profile of the end mill, and the corners of the sweep are sharp ...

Can you plunge with a ball nose end mill? You can, but I would try and avoid it. If you have to plunge it is a good idea to ramp down. This means moving along the X and/or Y axis while plunging at a shallow angle, i.e. less than 3 degrees.
Two issue I see achieving what you are asking: Guiding Curves supports only ball mill/spherical cutter, not bull mills. Guiding Curves cut direction is controlled by the guiding curve direction (s) - the result is motions in X, Y, and Z. I would suggest a look at Area mill. Take a look at my sample attached, it was created in NX1980. Expand Post.
