The ball mill is a key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. And the ball mill can grind various ores and other materials with dry type and wet type, and it’s divided into web overflow type ball mill, dry typeball mill, intermittence ball mill, rod mill, autogenous mill, ceramic ball mill according to its function and working theory.
We can supply high chrome, media chrome and low chrome manganese steel balls, kinds of liners for many different brands ball mills, if you plan to replace your steel ball, liners, just tell us your requirement about the material and sizes, and get the best offer from ZTIC.
Ball mill lining plate is used to protect the cylinder body, so that the cylinder body from the direct impact and friction of the grinding body and materials, but also can use different forms of lining plate to adjust the motion state of the grinding body, to enhance the grinding effect of the grinding body on the material, help to improve the grinding efficiency of the mill, increase output, reduce metal consumption.
China's current general wear resistant material series of high manganese steel series: such as high manganese steel (ZGMN13),
High manganese alloy (Zgmn13Cr2MoR), ultra-high manganese alloy (Zgmn18Cr2MoR), etc.
High manganese steel (such as ZGMN13) under severe impact or contact stress, its surface will rapidly harden, while the core still maintains a strong toughness, hard outside and tough inside both wear resistance and impact resistance.And the heavier the impact on the surface, the more full the surface hardening, the better the wear resistance.Because the hardness of high manganese steel itself is very low (HB170-230), the wear resistance is extremely limited before hardening. If the surface of high manganese steel is not enough to bear the impact force, the surface can not be fully hardened (after full hardening, the surface hardness can reach HB550 or below, otherwise), then the wear resistance will not play a role, and the wear resistance will not be shown.
Because Zgmn18Cr2 contains more manganese, the surface hardening can be more sufficient, so more wear-resistant.
Of course, ZGMN18Cr2 series (such as ZGMN18Cr2MORE) is also more expensive than ZGMN13 series.
