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.

In the tests, a by industrial tubular ball mill driven by a threephase motor (YTM6306, 1000 kW, 985 r/min) was operated at rpm (77% of critical speed). In the mill, the charge of steel balls was made up of three different diameter balls: 40, 50 and 60 mm corresponding to 40%, 40%, 20% mass ratio, respectively.

of the balltube mill is based on the twophase ball motion model proposed by Davis, according to which the ball first moves along a circular path together with the crushing cylinder, and then at the selection point it changes to a parabolic freefall path, hitting the crushing cylinder or balls at the drop point. Then the cycle is repeated [1 ...
