1. Preparation of samples in the
Steel Industry
Pedro Vellosillo
September 2015

2. One of the most important steps when
carrying out any type of analysis is the
Preparation of the Sample

3. At the moment of Preparing the Samples
the objective is to obtain an homogeneous
reduced sample from a bigger lot

4. 1.- The quantity of the sample has to be enough as to be able to
carry out all the necessary analysis. The sample must be
homogeneous and representative.
2.- The sample has to be collected and kept very carefully to avoid
any changes or contamination.
3.- The sample will need to be milled and mixed until becoming a
very homogeneus powder, of the appropriate size for analysis.
Make sure to avoid any kind of contamination during the
process.

• EQR-100 Mill
The vibratory disc mill EQR-100 is a milling unit especially
designed to obtain analitical granulometries in a wide variety
of samples, such as glass, earths, slags, metallic oxides,
ferroalloys, cements, ceramic materials, amongst many
others.
It can crush in a very short timespam a vast range of
different materials, from semi-hard to the hardest, fragile or
fibrous.
Easy to handle, and made of sturdy components, this mill is
a unit practically maintenance free.
