Grinding balls and cylpebs are designed for grinding various materials (clinker, coal, slag, ore) in ball mills.
At present, the basis of production is cast-iron grinding products, which have proven themselves to work in the attrition process in mills at low speeds.
In addition, production of rolled steel balls is launched, which will allow expanding the range of products for the needs of enterprises of the mining and metallurgical complex.
