Ball mill is one of the essential parts of mineral processing equipment. Many users of ball mill complain that the liner plate of a ball mill is with short service life and a high production costs. China Mining Equipment summed up key factors influencing the liner wear of a ball mil based on years of production experience, which as a reference for the users of ball mill. Hope it can help the users avoid a similar situation in production and prolong the service life of ball mill liner plate. The key factors influencing the liner wear of a ball mill generally include the following several points:

ball mill

1, The impact of media material

The generally used crushing media material include: various mine materials (manganese, copper, tungsten ore, chrome ore, etc.), various types of stone (limestone, granite, gneiss, basalt, gray rock, etc.) and industry coal used in power. The hardness of the media is the main basis that determines the liner plate wear, the higher hardness of the media, and the shorter service life of the liner; on the contrary, if the media is with a lower hardness, the service life of the liner will be prolonged.

2, The impact of operating conditions

1) Eliminate defects not timely.

2) Adjusting undeservedly makes the ball mill running at short positions.

3, The impact of liner material

The main parameters affecting the anti-wear effect is matching of the two index of hardness and impacting toughness of liner material. If the liner plate has a higher hardness, which means it has a good wear resistance, and the two factors basically is a proportional relationship. The impacting energy depends on the size of the diameter of steel ball and grinding tube.

4, the impact of the ball mill's designing and manufacturing and the installing quality.

The performance of the lining plate generally include the following two: one is to protect the cylinder; another is that the liner plate rotates at a specific speed to raise the ball to the required height to achieve the desired effect.

The quality of the liner plate is also direct factor affecting the normal operation of the mill.

Those above are the main factors affecting ball mill liners; we recommend that you should firstly consult the expert before you buy a ball mill. And you'd better go to the manufacturers with strength production and reputable brand purchase.
