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.
