Open Circuit Grinding. The object of this test was to determine the crushing efficiency of the ball-mill when operating in open circuit. The conditions were as follows: Feed rate, variable from 3 to 18 T. per hr. Ball load, 28,000 lb. of 5-, 4-, 3-, and 2½-in. balls. Speed, 19.7 r.p.m.

Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.

measured by pounds per square inch (psi), industrial blasting is effectively done between 20 and 90 PSI. The higher the PSI the higher the air speed. The volume delivered of the air/media mix is determined by the orifice or opening diameter of the nozzle with pressure blast systems or air jet diameter of the suction blast gun body.

4.1887 times the density of lead, which is 0.409 pounds per cubic inch, gives a weight of 1.713 pounds. What would a three inch diameter lead ball weigh? The radius of 1.5 inches cubed equals $3.375 ⋅ 4 ⋅ π = 42.410$, divided by 3, equals 14.137 cubic inches, times 0.409 ( the density of lead ) gives 5.782 pounds.
