Which Factors Affect the Service Life of Ball Mill Liner

Energy-saving ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials. The lining board plays two roles, one is protecting the cylinder, the other is elevating steel ball to the required height at the specific speed, to make steel ball falls like waterfall and then achieve the ideal grinding effect. Henan Fote summed up the main factors affecting the service life of ball mill liner, to help avoid similar cases in production and improve the service life of the ball mill lining board.

1.The influence of the medium

The medium that ball mill often break are: all kinds of mining materials, copper, tungsten ore, chrome ore, manganese ore, etc.), all kinds of stone, limestone, granite, gneiss, basalt, gray green rock, etc.), coal used in the electric power industry.Medium hardness index is the important basis that affects the lining board life. The higher the hardness, the shorter service life of the lining board. Otherwise, the longer service life.

2.The influence of lining material

From the analysis on the physical properties of the lining material, the main parameter that affect anti-wear effect is the matching problem of hardness and impact toughness. The higher hardness materials, the better wear-resisting performance, which is basically a proportional relationship. Because in running state, steel ball is a waterfall, the material and lining board will have an impact energy, the size of the impact energy depends on the size of the grinding ball diameter and tube diameter.

3.The influence of design and manufacturing and installation quality

Poor quality lining board, such as out of flatness, cylinder deformation, mismatch of plate and liner, liner and cylinder, mechanical property, chemical composition do not meet the requirements etc. They are the direct factors influencing the normal operation of ball mill.
