The formula for calculating the average grinding balls diameter in the mill the average grinding balls diameter, mm;; i the maximum grinding ball diameter in each class, mm; mi the grinding ball mass of each class, kg. The grinding balls bulk weight determined by using tabular data. The grinding balls bulk weight corresponds to the calculated average grinding balls diameter in the mill.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and 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 steel balls.
Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
Secondary Grinding Ball Mills In secondary ball milling, abrasive and corrosive conditions predominate. The smaller balls [lt; 2#189;, (65 mm)] typically used in secondary milling environments effectively reduce the impact component of wear to the point where grinding media must be primarily designed to reduce abrasive and corrosive wear.

With this in mind, it is interesting to make a qualitative comparison of the ball size distributions which should be generated by 76 mm pearlitic carbon steel balls versus 76 mm martensitic alloy steel balls in the m mills. The 76 mm pearlitic carbon steel balls used have a relatively flat hardness gradient from surface to center.

Diameter depending on the material, ranging from mm to 2 mm for small media mills, up to 1/8 to 1 for traditional Attritors and up to #189; to 2 for ball mills Composition metallic grinding media like carbon steel, forged steel, stainless steel or chrome steel grinding balls are best for some applications, while others require nonmetallic media made of alumina, ceramics, glass, silicon carbide, zirconium oxide
In the grinding material process at ball mills becomes necessary to calculate the bulk weigh of used grinding media. The bulk weigh of the grinding balls is necessary to understand the grinding balls mass in the cube, the grinding balls mass loaded into the mill, the prevention of mill overloading with grinding balls, etc. These data often used in operational management of grinding process.
