Answer: According to the manufacturer’s data, the planetary carrier rotation speed of 422 rpm and the jars rotation speed (around their own axes) of 800 rpm are used in the laboratory planetary mill MPP-1. Nevertheless it is not correct to compare different planetary mills only according to the planetary carrier rotation speed.

Ball Mill - an overview | ScienceDirect Topics
The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds.
Ball mill - Wikipedia
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

Periodic review and continuous ordering
Periodic review and continuous ordering D.R.J. Prak, R.H. Teunter, and J. Riezebos February 7, 2014 Abstract There exist many inventory control studies that consider either continuous review & continuous order-ing, or periodic review & periodic ordering. Mixtures of the two are hardly ever studied. However, the
Countercurrent chromatography - Wikipedia
Countercurrent chromatography (CCC, also counter-current chromatography) is a form of liquid–liquid chromatography that uses a liquid stationary phase that is held in place by centrifugal force and is used to separate, identify, and quantify the stone components of a mixture. In its broadest sense, countercurrent chromatography encompasses a collection of related liquid chromatography ...
