Abstract:
     This invention relates to ball mill made of low-alloy white iron with high-strength white iron which is used for grinding ore materials. Its chemical components (Wt. %) include C (1.8-4.1), Si (0.2-2.0), Mn (0.3-2.5), Mo (0.1-1.5), Cu (0.1-1.2), W (0.1-1.0), V (0-1,0), Ti (0-1.2) and the remainder being Fe. It is made up only by cupola and metal casting and has advantages such as high strength, good toughness and excellent antiwear nature. The ball mill loss ratio is less than 100 g / ton-coment for dry grinding or 500-900 g /ton-ore for wet grinding. The ball mill is suitable for various grinder.
