Rod mills how they function

Rod Mills How Do They Work? Rod mills are very similar to ball mills except they use long rods for grinding media The rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill To prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 1 4 to 1 6

How does the ball mill work?

17/01/2011Re How does the ball mill work? 01/17/2011 3 12 AM When the ball mill works motor and speed reducer transmit torque force to big and small gears of ball mill so the barrel rotates When the barrel rotates Steel balls or other grinding media in the barrel are lifted to a certain height and fall down freely so materials in the barrel are impacted

Planetary Ball Mill PM 100

Planetary Ball Mills are used wherever the highest degree of fineness is required In addition to well-proven mixing and size reduction processes these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and
