fine grinding of dry laboratory samples of rocks, minerals, ores and other materials in preparation for phiysical-chemical analyses


Innovative patented grinding fittings provide higher technical and economic performance in comparison with the widely-known grinders IV-3 and IV-4:

— higher capacity;

— the possibility to grind a larger sample amount;

— smaller grain size of ground material (down to 20 ?m);

— higher reliability of the vibratory drive
