Study of residence time distribution and mill hold
The mill was loaded with 26.3 kg of 5mm steel balls, corresponding to 60% of the mill volume filled by a ball bed. A steadystate condition was established by feeding the sand at a given feed rate until the solid discharge rate attained the same value as the feed rate and the size distribution of the product did not change with time. The RTD was measured by carrying out an impulse test using

Grinding control strategy on the conventional milling
the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio, and hence the control loop will add more water to keep the ratio constant. However, the amount of slurry reporting as fresh feed to the second milling circuit will increase.

The influence of mill speed and pulp density on the
mill discharge density (before dilution) obtained during the sampling. The ball charge, and hence the volume of the voids between the balls in the mill, is known and we are then able to calculate the factor 'volume pulp/volume voids between the balls'. Repeatability The repeatability of the pilot plant was investigated in the past with 2 repeat test runs with the ∅0.82 x 1 m grate

THE OPTIMAL BALL DIAMETER IN A MILL
The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.

The speed at which the ball mill jar rotates is responsible for maintaining the slope of the cascading media pile, which is known in the industry as the "angle of break." This angle can be between 40 to 65 degrees as measured from the horizontal. If the angle is too shallow, the media will not cascade much from one end to the other. from top to bottom while striking nothing in between. Still
