fine grinding of dry laboratory samples of rocks, minerals, ores and other fragile materials, including flow rolls of iron-ore pellet production in preparation for phiysical-chemical analyses.


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

— higher capacity (per amount of ground sample);

— the possibility to grind a larger sample amount;

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

— higher reliability in operation
