MQG3660 Ball Mill Fault Analysis
Introduction
MQG3660 ball mill is a type of mill commonly used for grinding materials in the mining industry. This type of mill is commonly employed in ore grinding processes, in which material is fed into the mill from a feed hopper and then pressed against a grinding disc, which rotates around an axis. The material is then reduced in size when the grinding material is forced between the grinding disc and the internals of the mill.
One of the most common problems encountered with this type of mill is known as ‘tooth-chattering’, in which the teeth of the grinding discs grind against the material at an uneven rate, resulting in vibration and noise. This article will discuss the various methods that can be used to identify the source of the problem, as well as the appropriate actions to take in order to correct it.
Identifying the source of the problem
The first step in diagnosing and correcting tooth-chatter is to identify the source of the problem. There are a variety of causes that could be responsible, and they can be classified as either mechanical or environmental.
Mechanical causes include wear of the mill internals, incorrect grinding media selection, incorrect installation, or a poor distribution of material throughout the grinding chamber. Environmental factors such as temperature and humidity changes can also have an impact on the behaviour of the mill.
In order to identify the source of the problem, it is necessary to pay close attention to the mill’s operation when it is running. It is also important to monitor the conditions outside of the mill, such as air temperature and humidity.
Corrective measures
Once the source of the problem has been identified, it is necessary to take corrective action in order to reduce or eliminate the issue.
For mechanical issues, the most common corrective action is to replace the worn parts or to adjust the grinding media selection. If the internals are found to be in good condition, another option is to install dynamic separators or to modify the grinding chamber in order to ensure a better distribution of material throughout the mill.
If environmental factors are responsible for the problem, the corrective measure would be to set the mill’s environment-control system to maintain a consistent temperature and humidity level.
Conclusion
MQG3660 ball mill is a common type of mill used in the mining industry for grinding materials. One of the most common problems encountered with this type of mill is known as ‘tooth-chatter’. This article discussed the various methods that can be used to identify the source of the problem, as well as the corrective actions that can be taken in order to correct it. Through proper diagnosis and corrective action, it is possible to ensure that the mill operates correctly and efficiently.
