Mining Process Balls
This type of grinding balls are produced with different chemistries、 steel and cast iron, with chrome contents ranging from 1% to 32% and sizes ranging from 4.8mm to 150mm. Different heat-treatment cycles are used to impart specific metallurgical properties depending on the intended application. Whether the predominant wear mechanism is abrasion, corrosion or impact, NINGHU can offer a product to suit.
What is Mining Process Balls?
Mining process balls, also known as grinding balls or grinding media, play a crucial role in various mining processes, particularly in ore grinding and mineral processing. These balls are designed to withstand high impact and abrasion, ensuring efficient comminution of ore particles and optimal performance of grinding circuits. With a focus on durability, efficiency, and quality, NINGHU offers a comprehensive range of Grinding Balls tailored to meet the diverse needs of mining operations worldwide.
