Now there are many mining mineral processing equipment will be used in ball mill, ball mill liner and many people reflect the life is too short, so today let Yufeng person we explain the ball mill liner is unaffected wearing it: 1.The impact of a ball mill grinding media often grinding of raw materials: various types of mining raw materials (copper, manganese ore, manganese ore, chrome ore and other minerals), various types of non-metallic minerals (limestone, granite, gray rock, rock chip mill) and coal used in the power industry.Medium hardness index is to determine the important reasons for failure of liner wear, the higher the hardness of the ore, the shorter the life of the liner, on the contrary, it will increase the life cycle.2.The impact of a job runs), to avoid untimely repair defects, such as loose bolts fall, individual liner off, if not timely replacement of the case, the defect will gradually spread, on the other cylinder liner and cause very major damage.2), the feed is uneven, improperly adjusted, there running short positions, leading to friction and impact directly balls and cylinder liner, forming two-body wear, this fragmentation of the ball on the liner and the wear chance amplitude increases, causing great damage to the liner, is a very bad operation.3.Ball mill liner material of liner material according to the physical properties, anti-wear effect of the main parameters affecting the hardness and impact toughness is the problem of matching two indicators, the harder the material, the better the abrasion resistance, it may reach species is directly proportional to the mill during operation, the ball falling like a waterfall on the materials and produce an impact energy liner, the size depends on the size of the impact energy, ball mill shell diameter and the diameter size.4.Mill design manufacture and installation of the impact of technology liner has two roles, one person to protect the cylinder, the other is the speed of the ball at a specific elevated to the required height, so that the ball was falling like waterfalls, rolling mill to achieve the desired results.If the liner made of poor quality, if not flat, casting is not strong, the cylinder wall deformation of the liner and the liner installation, between the liner and the cylinder wall does not match and their casting defects, mechanical properties, chemical composition does not meet the eligibility requirements, which are affecting the normal operation of ball mill direct factor.
