Torus manufactures forged grinding balls of the following diameters 20mm, 25mm, 30mm, 35mm, 40mm, 50mm, 60mm, 65mm and 70mm. larger diameter balls are available on order. advantage torus uniform hardness, close dimensional tolerance and perfect shape results in low wear rate which leads to steady milling conditions.
22 l sample were filled in the drum of the Drum Mill TM 500, 80 kg of 30 mm grinding balls were added. The drum mill was operated for several hours at 50 rpm. The fineness was measured after 1 h. 1h D90 130 181m The optional separation unit to separate the ground sample from the balls was used.
Designed for maximum abrasion resistance using high carbon content and high hardness levels, the Molycop Ball Milling range is manufactured all over the globe, delivering outstanding performance.
In most secondary Au, Cu, and Mo grinding, the relative wear rates of high Cr compared to forged steel show a performance improvement of 25 30, similar to that seen in primary grinding. However, for corrosive environments with low abrasion, the high Cr ball can result In Improvements of 50 or more compared to forged steel.

The surface of the cast grinding steel ball is not allowed to have the casting defects such as the crack, and the obvious gas porosity, inclusion, shrinking cavity, cold shut, elephant skin, etc.
It is not allowed to have the shrinkage cavity, shrinking porosity, gas porosity, inclusion, and other cavity defects on the section including plane pasting through the pouring gate and the ball centre.
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 Grinding Balls Diameter Mm Chromium alloy is the main composition of casting steel ball with diameter of 6 mm to 140 mm According to different chromium content the grinding ball can be divided into three kinds namely low medium and high chromium balls 60mm forged steel ball grinding media for gold mines Forged Steel Balls For Ball
