/// Grinding material properties
IKA mills can be used for the grinding of soft, hard, brittle, fibrous and
elastic materials. The grinding of solid samples is essential to ensure precise
analysis. It is important that the grinding leads to the homogeneity and
desired fineness of the sample. The type of mill to be used depends on the
properties of the substance and the quantity of the sample. For example,
brittle materials are ground with a beater, fibrous materials with a blade,
and hard/brittle materials are ground with a special hard metal cutter.
Below are the examples
Soft: Meat, pastilles, cheese, tissue…
Hard: Coal, coke, maize, salt…
Brittle: Stones, glass, ceramic, concrete…
Fibrous: Leaves, paper, wheat, grass
Elastic: Rubber, plastic, elastomer, gummy bears…
Small sample quantities are generally ground with a batch mill. Here,
a particle size spectrum of the ground material can be expected.
Larger quantities can be ground with an inline mill. Here, the sample
passes through a sieve, which leads to the ground material achieving a
defined particle size.
Problems can arise when soft and tough materials such as rubber or
plastics have to be ground. The problem can be solved through the
embrittlement of the sample with dry ice or liquid nitrogen. The sample
can then be ground without diculty.
