Grinding Balls are made from high carbon steel bars with the proper alloying elements. Bars are heated to high enough temperatures to make them sufficiently malleable to be cut and formed into nearly perfect spheres. Balls are then heat-treated to provide them the necessary wear and impact resistance properties. Fine grinding of mineral ore particles. Can also be used for pulverising of coal, cement and other building materials. High carbon steels (0.5 - 0.95%C) with controlled amounts of alloying elements. Logistics: As a result of this diverse geographical spread, we have established a vast network of logistics solutions to suit the individual requirements of our customers, no matter how challenging. Technical: We take pride in our ability to back our product quality with the technical support necessary to ensure the optimum outcome is obtained from the application of our grinding media. This service ranges from the recommendation of ball sizes to the optimisation of steel grades, through to determination of graded mill charges for new milling projects.
