What it is the optimun speed for a ball mill

18/10/2006018332Congratulations on your ball mill You'll want to further reduce your motor speed by 31 to mill more efficiently. Right now, your RPM is just slightly under the speed where the media won't do any work. The optimum speed for your jar to turn is around 90 RPM like Frozentech said.

DESIGN AND FABRICATION OF MINI BALL MILL.

This project is to design and fabricate the mini ball mill that can grind the solid state of various type of materials into nano powder. The cylindrical jar is used as a mill that would rotate the material that about to be ground, a motor is used to power the system so that the jar can rotate in high speed and using the regulator controls the speed of the rotation of the jar.

Ball Mills Mine Engineer.Com

A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a

OverviewDescriptionWorkingApplicationsAdvantages of the ball millVarietiesSee also

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steelballs. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other e
