See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller comparatively diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing. Industrial ball mills can be as large as 8.5 m 28 ft in diameter with a 22 MW motor, drawing approximately 0.0011% of the total world's power see List of countries by electricity consumption . However, small versions of ball mills can be found in laboratories where they are used for grinding sample material for quality assurance. The power predictions for ball mills typically use the following form of the Bond equation: $$ \displaystyle E10W\left \frac 1 \sqrt P 80 - \frac 1 \sqrt F 80 \right \, $$where E is the energy kilowatt-hours per metric or short ton Wikipedia & 183; CC-BY-SA 许可下的文字Ball Mill vs Rod Mill How To Choose Ball Mill or Rod 30/12/2019& 0183;& 32;In the ball mill, there are lattice ball mill and overflow ball mill in common use named by different ore discharge structure , while there are only overflow type and open type rod mill.
