The main role of the liner is to protect the cylinder, so that the cylinder from the direct impact of the grinding body and material and friction, but also can be used in different forms of liner to adjust the movement of the grinding body to enhance the crushing effect of the grinding body on the material, which will help to improve the grinding efficiency of the ball mill, increase production and reduce metal consumption. However, in the ball mill grinding process cylinder liner will inevitably encounter damage, it is necessary to replace the ball mill liner, in the replacement of what matters need attention? Henan Jinyu wear-resistant materials limited company technical personnel for everyone to analyze.
1, external forces: energy-saving ball mill accidentally start will create personal injury; dismantle the sound insulation cover, hopper using a sledgehammer slipped off to create personal injury; welding arc burns the eyes of the staff; replacement of energy-saving ball mill liner using a sledgehammer slipped off or ball mill liner fell, causing personal injury to injured personnel; cylinder crushed steel ball sliding injuries to the personnel; energy-saving ball mill import and export pipeline falling objects hurt people.
2, ball mill drum residual coal dust in the open fire caused by fire.
3、Electrocution: personal electric shock occurs when using electric welding machine; personal electric shock occurs when using electric tools; personal electric shock occurs when using lighting. According to the load situation, the powder making power can be concentrated in 1 or several ball mills, and stop using other ball mill equipment.
4, strict quality control of liner installation, liner and cylinder if not match, can be replaced liner or the cylinder local digging and patching treatment, fixed, tightening wedge shall not be forced due to the bolt hole is not centered.
5, asphyxiation: poor ventilation within the cylinder, resulting in personnel asphyxiation.
6, clever use of the characteristics of the liner, the new replacement of the village plate of the ball mill, according to its characteristics, the first use of slightly lower hardness of the steel ball running 1 to 2 months, to be the hardness and toughness of the liner plate has a certain amount of improvement, and then use a slightly higher hardness of the steel ball, this can effectively improve the service life of the village plate.
