Analytical mill – A 11 basic
Process type: batch
Operating principle: cutting/impact
Batch mill for 2 different grinding procedures:
+ Impact grinding of hard, brittle or non-elastic grinding materials with high-grade stainless steel beater. This beater can be used for a Mohs hardness up to 6 (incl. with delivery)
+ Cutting grinding for pulverizing soft, fibrous materials with a cutting blade (not incl. with delivery).
Moist and/or sticky materials can be pulverized by adding water.

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
Small sample quantities are generally ground with a batch mill. Here, the samples are ground very smoothly and 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
