The ball mill is a device that destroys the raw materials again after they are mined or broken into small pieces to make their particles smaller. From its name, it can be understood that the ball mill is equipped with steel balls in a closed cylinder. Through the rotation of the cylinder, the steel balls fall from high places and collide with

Steel Ball Mills & Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or
grinding tests were run in a 12 x 12 Bico ball mill with the ball charge recommended by Bond for work index determinations. The feed was stage crushed in rolls to pass a 6-mesh screen and then split into 1,200-gram samples (equivalent to a volume of 700 cc). The mill speed was 70 rpm.
Batch Grinding Model
For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

Nov 18, 2008 Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a specific operating speed for most efficient grinding.
