The critical speed of a ball mill is determined by the rotation speed of the mill and the diameter of the grinding media. It is calculated using the formula: critical speed = 42.3/sqrt(d), where d is the diameter of the mill in meters. Operating above the critical speed can lead to cascading and ineffective grinding, while operating below can lead to cataracting and unproductive milling.
The diameter of normal size pencil lead is about 0.7 millimeters.
No, a lead ball is more dense than a sponge ball because lead has a higher density compared to the sponge material. Density is the measure of how much mass is contained in a given volume, so the lead ball would have more mass packed into the same volume as the sponge ball.
Lead weight sinks in water since its density is greater than that of water.
A small object with high density, such as a lead weight or a dense metal ball, would have a small capacity but a large mass due to the arrangement of its particles.
The weight (not mass) is 69.05 pound weight.
A cubic inch of lead is about 0.4 pounds. So 10 pounds would be about 25 cubic inches which would make a ball about 3.6 inches in diameter. That is slightly larger than a softball.
l= .5 in d= .312 in dxdx .7854 x .5 = .0382269 cubic inches or .0000221 cubic feet multiplied by the known weight of lead (712 lbs/cubic foot) .0157352 pound lead cylinder
The gauge of a firearm is a unit of measurement used to express the diameter of the barrel. Gauge is determined from the weight of a solid sphere of lead that will fit the bore of the firearm, and is expressed as the fraction of a pound (e.g. a 1/12th pound ball fits a 12-gauge bore). The term is related to the measurement of cannon, which were also measured by the weight of their iron round shot; an 8 pounder would fire an 8 pound (3.6 kg) spherical cast iron ball and had a bore diameter of about 91 mm (3.6 inches). ( I do love metric measurements where the diameter in millimeters is the measure of a gun's "gauge")
A ball screws measurements are determined by many things. For instance, a 1, 3, 4 foot ball screw has the nominal diameter of 3/8’s, the nominal root diameter of .300 inches, and is .125 lead/reverse. A ball screw is a mechanical device used in the translation of rotating motion to a linear motion. This is done by a ball screw, with very little friction. A ball screw can reduce friction and operate with preload. This is effective in the elimination of the backlash between rotation and linear motion.

A mathematical point is only a location, and has no dimensions. Of course, when you mark the point on paper, it has the same diameter as the lead in your pencil, or the ball on your BIC.
A pound of lead was divided into equal parts and then formed into perfect balls and the diameter of the ball would be the gauge. I.E. One pound of lead divided into twelve (12) equal parts and one was rolled into a perfect ball; the size of the ball is twelve (12) gauge.
Yes- but they are of a different weight- the steel shot being lighter.
This is often a tennis ball filled with lead to weight it down. It is then passed between skydivers in freefall. This is a tricky and skilled thing to do by freefly skydivers.
The critical speed of a ball mill is determined by the rotation speed of the mill and the diameter of the grinding media.

My .32 cal. mold produces pure lead round ball that weigh about 47 grains or about .107 oz.
