Its capacity to ground, mix and homogenize quickly small quantities of sample, makes of the EQM-402 Mill your great ally in the preparation of samples. This mill has been designed for the final preparation of small quantities of hard, semi-hard and fragile samples – up to 15 g. -. It can prepare two samples simultaneously and reduce them parting from an initial size of 0.8 to 1.5 mm. until sizes of less than 10µ in short periods of time – 1 to 4 minutes -. Due to its effectiveness/time rate, this mill is ideal for the final reduction in the preparation of samples by fusion – using grain sizes of 10µ speeds up the homogeneization of the sample in the flux, noticeably reducing the fusion times -. It is also especially recommended for preparing and mixing samples with binding agents for its subsequent analysis via X Ray fluorescence.

2. EQM-402 Ball Mixer Mill
The EQM-402 Ball Mixer Mill is your great ally for
the preparation of samples for analysis, as it can
crush, mix and homogenize small volumes of
sample in very short time. It has been specially
designed for the final preparation of hard, semi-
hard and fragile samples – up to 50 ml. -. The
mill can process two samples simultaneously
and can reduce them, parting from an initial gran
size of 0.8 to 1.5 mm., to sizes of less than 10µ, in
practically no time – 1 to 4 minutes -.
The excellent efficiency-time ratio of this unit
makes it the ideal help for the final reduction
of grain size to prepare samples for fusion
processes – using grains of less than 10µ
speeds up the homogenization of the sample
with the flux, shortening the fusion times
noticeably -. It is also specially recommended
for preparing and mixing samples with
binding agents in order to make disks/pellets
by pressure, for analyzing those later under
X-Ray.
The EQM-402 Mixer Mill allows us to reduce
samples in dry to a final grain size of 10µ in 1
to 4 minutes milling times, just with a desktop
unit. Simple to manage thanks to a visual
software and a touchscreen from which you
can control the microprocessor, that stores 5
working programs whose parameters can be
reset at wish, such as the speed and milling
time.
The unit has got two sample containers,
easy and safe to fix, connected to a powerful
engine. A series of hinges transfer the power
of the engine to the milling jars, in order to
produce a strong agitation. Within the jars,
the sample collides heavily against the milling
balls, of different diameters.
Very easy to use. The sample is placed in
the milling jars together with several balls,
depending on the type and initial size of
the sample and the final grain size sought.
Then select a program and press “start”. The
oscillating movement of the jars causes the
impact of the balls with the sample, crushing,
milling and mixing all within. The combination
of balls of different diameters lets you achieve
different final grain sizes, according to your
milling needs.
