Since ore particles must go through the grinding process, steel grinding media are ideal for such a grinding process. Steel ball grinding media are made from alloys of iron and carbon. By increasing the carbon content to produce cast irons, both the hardness and wear resistance are improved significantly.
The wear resistance, hardness and fracture toughness of the ceramic media also influence mill parameters, such as energy efficiency, internal wear and operating costs. Property advantages, reasonable cost and a low mineral surface degradation are the goals of a good ultrafine grinding process. Synthesizing Grinding Media

Magotteaux Mining Grinding Media One Cast High Chrome is the best option when the situation requires optimal wear resistance against abrasion and corrosion. Available in diameters of 0.5-4 inches, Magotteaux Mining Grinding Media One Cast High Chrome is appropriate for ball mills and tower mills, along with wet and dry ore applications.
In the case of wet grinding, corrosion also plays an important role in increasing the overall wear of the media [4, 5]. It is well known that for good wear resistance, the grinding media should have adequate hardness to resist the abrasive actions of the ore and sufficient toughness to withstand the impact forces prevailing inside the mill.
grinding media High-Chrome grinding media combines martensitic structure with hard chrome carbides, This provides the best wear resistance against corrosion and abrasion of all kinds. Magotteaux´s expertise enables them to select the alloy which fits your application perfectly and minimizes the costs.
Grinding media are the means used to crush or grind material in a mill. It comes in different forms such as alumina oxide balls, ceramic cylinders, or soda lime glass.
