Ball mill is one of the necessary part of grinding machine. Many customer of ball mill complain that the liner plate of a ball mill is with short service life and a high production costs. The key factors influencing the liner wear of a ball mill generally include the following four points:
1.Media material
The generally used crushing media material include: various mine materials (copper, manganese, tungsten ore, chrome ore, etc.), various types of stone (limestone, gneiss, basalt, granite, 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 grinding media, 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. Operating conditions
1) Eliminate defects not timely.
2) Adjusting undeservedly makes the ball mill running at a short position.
3. 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 that 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. Ball mill's designing, manufacturing and the installing quality
The performance of the lining plate generally include the following two point: one is to protect the cylinder; another is that ball mill 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 ball mill.
Those above are the main four factors affecting the liner wear of a ball mill, if you have any question about the ball mill machine,please contact us without hesitation.
