Chimwani et al. (2015) developed a simulation program that could predict optimal makeup balls to be added in order to achieve a required product fineness. Fine grinding is believed to lead to high leaching rates as predicted by the common leaching models because value material gets more liberated hence requires less time to leach.

As attrition and oxidation wear the balls down, new ones are added. The degree of product oxidation is primarily a function of air flow through the system and, to a lesser degree, the ...

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

A ball mill is a rotating drum with dozens of lead balls inside. The 3 chemicals are loaded into the ball mill, along with the lead balls, sealed shut and allowed to rotate for anywhere between 1 and 24 hours. As the ball mill rotates, the lead balls will crush the chemicals together, forcing some of the potassium nitrate into the pores of the ...
