To really choose, I guess it depends on the material and your mill (vial, RPM, media, filling volume). If you were going for smaller powder size, typically it''s going to take smaller diameter balls to get there too. Then, the optimal mass ratio of ball to powder in ball mill is 7.5*24/(2.5*17.6)= 4.09 to 7.5*21/(2.5*11.2) = 5.63.

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

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow
Get Price3 shows the typical variation of the S values with particle size xi for different ball diameters. For the same amount of ball charge, the number of balls in the mill decreases as the ball size increases. Thus, the S values are lower for larger balls . However, larger balls are capable of breaking large particles; therefore, the size at
