High chromium balls are recognized as better grinding media in terms of wear rates than forged steel balls, which are conventional grinding media in the milling process of iron ore. In this research work, the wear rate of high chromium balls and austempered ductile iron (ADI) balls as crushing media in a ball mill are compared.

The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills. This work reviews the application of balls in mineral processing as a function of the materials used to manufacture them and the …
One of the earliest models was that of Bond (1943), who proposed a specific consumption rate for balls Ω E (kg/kW h) in wet mills of (14) Ω E = 0.16 (A i-0.015) 1.3 and for dry balls (15) Ω E = 0.023 (A i) 0.5 where A i is an abrasion index that depends on the ball material, which could range from A i = 0.016 for dolomite to A i = 0.891 for ...

Steel balls are one of the most widely used grinding media in cement ball mills, their diameters can range from 20mm to 150mm according to different grinding requirements. In a cement ball mill, generally, φ50-100mm steel balls are used in the coarse grinding chamber, φ20-50mm steel balls are used in the fine grinding chamber. 2. Short Cylinders.
Common applications for our ball mills is grinding of clinker for cement manufacturing, mineral ore's, calcium bauxites, silicates and other materials that can be ground into fines either by wet process or by dry process. …

In each test 15 balls out of a total ball load of 9000 g, i.e., 126 balls (136 for HCCI balls), were marked and their weight loss recorded after a certain grinding time. The surface layer of each ball type was removed prior to conducting the marked ball wear tests by grinding for 30 hours in the porcelain mill.
The Allmax® grinding balls are exceptionally wear resistant, thanks to the use of high-alloy steel with 11 to 19% chromium content.
