Instruments used to measure particle size have now achieved a degree of accuracy which was inconceivable years ago. Tolerances are constantly being reduced and the latest versions on the market operate faster and more accurately than their predecessors.

The most obvious truth concerning the Vibrating Cup Mill is: it has stood the test of time and is still EFFECTIVE! There is hardly any other mill faster at grinding hard and brittle materials down to analytical fineness is so easy to clean!

The aim of all comminution is to achieve a certain fineness. During comminution, particles of a starting material are broken to form many smaller particles.

A clean and constant wear on the inner grinding bowl surface is a question of the amount of grinding balls and size, material amount and size (coarse or fine), the grinding condition like wet or dry grinding, the grinding duration and the adjusted rotations of the planetary system.

The manufacturing of cement is a very energy intensive production. Here for the most part coal is utilized as an energy carrier, but in the future the use of secondary fuels will increase and also the need of the analysis of such materials.

RoHS stands for "Restriction of Hazardous Substances". It's the directive of the European Union (EU) that restricts the use of six hazardous substances in electronic components shipped into Europe. The Vibratory Micro Mill PULVERISETTE 0 was utilized for RoHS tests.

Medium-hard to hard materials with edge lengths up to 95 mm can be pre-crushed with the FRITSCH Jaw Crusher PULVERISETTE 1 so an additional fine comminution with many FRITSCH mills is possible.

In the laboratory sector planetary ball mills are usually utilised to reduce the size of a broad range of samples in batches at high energy.

During a dry grinding, often only after a short grinding period hygroscopic material tends to stick. A second factor causing this is the static charge respectively adhesive powers of fine particles.
