The operator puts 25 kilograms of material in the inlet funnel and starts the process at the central control box. A vibratory feeder underneath the inlet funnel evenly feeds the bucket elevator. The bucket elevator lifts the material and feeds the jaw crusher (type LMFC250) which reduces the material to 2mm.
The grit material goes, using a flexible connection, to a rotary sample divider which divides the sample in ten equal parts of 2,5 kilograms (sub samples). The alloys have a density between 3 and 8 kg/liter, giving a partial sample volume of 500 to 800 ml.
This sample will be pulverised in a ring mill (type LM2000) to reach the desired end finesses of 125 micron. The external lab needs 12 to 15 grams of this product to make it into a tablet that can be analysed with an XRF-machine (X-ray fluorescence).
