Through different sieves of various size, aggregates can be categorised by their size and their grading curve can be identified.

Pan granulator

Lupe

APA03 by Erweka

The agglomeration of finely distributed material will be applied to improve the transport and processing properties of the granulates.

Mills

Mortar grinder

pulverisette 2 by Firma Fritsch

The mortar grinder prepares solids to achieve a specific grinding fineness to analyse the sample. In this process a solid can be grinded down to 10-20 µm.

Ball mill

Lupe

by MLW

Through the clash of small balls, the sample will be crushed and step by step ground.

Disc mill

Lupe

There are two discs in the mill, one a ring profile and the other a circle profile. Through rotation, friction and compression the sample will be milled up to a size of 10 μm.
