Mechanisms of Grinding Modification by Chemical Additives

above, amine decreased the grinding rate in the acidic pH range owing to increased flocculation of quartz fines in the presence of amine in this pH range. These results show that grinding of quartz can be improved by amine if other conditions such as pH are controlled. Also, the results indicate that the effect of chemical additives on grindingget price

Method for the production of carbonates by wet grinding

Wet grinding is a grinding operation using a liquid vehicle, that is to say a grinding operation in a liquid suspension. Wet grinding generally requires a smaller amount of energy for a given amount of material to be ground, since the viscosity of the liquid, which is greater than that of air, as a vehicle creates more favorable conditions forget price
