· Grinding balls are spherical components used in grinding mills to crush and grind raw materials, turning them into fine powders. These balls are essential in the mining industry to extract valuable minerals from ore. Steel Grinding Balls: Steel grinding balls are a subset of grinding balls, specifically made from high-quality steel.

· This process includes ore crushing, screening, ore grinding, classification, and magnetizing roasting of weakly magnetic iron ore. If necessary, desliming and washing will be done in advance, in order to ensure the ore (crude ore) from an open-pit mine or underground mine can be delivered to the mineral processing plant.

· When dealing with argillaceous iron ore with high water content, or when restricted by terrain conditions, a three-stage open-circuit crushing and rod mill crushing process is sometimes used. That is to relax the particle size of the finely crushed product to 25~30mm, and add a rod mill for fine crushing, which is equivalent to a four-stage open
