The chemical composition of the high chromium type product should conform to the below table. We can also manufacture the product with special chemical composition in accordance with the requirements of the customers.
The nominal diameter, allowable deviation, maximum diameter, minimum diameter of the cast grinding steel ball should be in accordance with the following table.
The high chromium type of product can be manufactured with the mechanical properties following the requirements of customers.
The feed ore in primary grinding mills is typically very abrasive owing to its particle size, shape, and mineralogy. Wear speeds approaching or exceeding 20 mhr. have been measured for very abrasive Au. Cu, and Mo ores, while wear speeds on the order of 10-15 mhr. have been encountered in softer primary ores.
Steel grinding media used in primary grinding must be designed for maximum abrasive wear resistance while maintaining good toughness. Toughness is particularly important in grate discharge mills where pulp levels at the discharge end of the mill can approach zero. Moroz and Lorenzetti 1981 found that maximum abrasion resistance is achieved by the combination of alloying with maximum amounts of carbon and heat treating the balls to their optimal microstructure.
High Cr media for primary grinding will typically contain maximum levels of eutectic carbide 30 8211 35 by volume and are heat treated to their maximum hardness HRC 65 8211 68. However, not many high Cr balls are used in primary grinding because the improvement obtained in wear resistance relative to steel, typically 25 8211 30, is not enough to offset Its higher cost.
Forged steel balls are welcomed in different kinds of mines like golden mines copper mines etc equipped with different size of ball mills.

Ball mills are commonly used for crushing and grinding the materials into an extremely fine form The ball mill contains a hollow cylindrical shell that rotates about its axis This cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it.
The ball mills are the commonest unit for rock fragmentation. The operating principle of mechanism is very simple the rotation of a shell with steel grinding balls corresponding to GOST. The content is pulverized or fragmented into larger fractions due to rotation of a shell. The balls are divided into the following groups by their hardness.
The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber.
To use the mill as a rock tumbler, just leave out the steel balls, add rocks, tumbling grit and water, and let it spin. Here is a video of my home-made ball mill in operation with a brief explanation of all the parts and how I put it together.
So, the chrome steel balls in your ball mills grind your productnot each other. Through hardened and rust resistant, the high density and superb hardness of FOX Chrome Grinding Balls make these grinding media balls ideal for ball mill grinding, including the crushing, mixing, and dispersing of even the hardest raw materials and the most viscous liquids. FOX Chrome Steel Balls will transform your ball mill.
