What about the abnormal powder discharge of Raymond mill?
Raymond mill is a kind of grinding equipment widely used in mines, cement plants and chemical plants. It is an important equipment for deep processing of non-metallic minerals and is loved by the majority of users. However, most users will inevitably encounter abnormal powder production of Raymond mill. In order to help you solve this problem, Xiaobian specially made the following analysis, hoping to help you.
Causes of abnormal powder discharge of Raymond Mill
1. Loose sealing of powder lock
If the sealing work of the powder locking device is not done in place during the grinding process of Raymond mill, the powder back suction phenomenon will be formed, resulting in no powder or less powder. Therefore, check the sealing of the powder locking device and adjust the sealing degree.
2. The analyzer did not work
The analyzer of Raymond mill is responsible for analyzing the size of the finished powder, whether it meets the finished product standard, and whether it needs to be sanded again. In the case of serious wear of the analyzer blade, it can not play the role of classification, which will cause too coarse or too fine powder. In this case, it can be solved by replacing a new blade.
3. The fan is not adjusted properly
If the air volume of Raymond pulverizer fan is not adjusted properly and the air volume is too large, it will also cause abnormal powder output of the pulverizer. If the air volume is too small, the powder output will be too coarse. If there is no abnormality in other conditions, the air volume of the fan shall be adjusted to correct the powder output particle size.
4. The blade has failed
The blade of Raymond mill is responsible for scooping up the materials. When the blade is used for a period of time or the quality is not strong enough, the wear is large and the materials can not be scooped up, which will also cause no powder or less powder. Therefore, a new blade needs to be replaced to ensure the normal operation of the equipment.
How does Raymond Mill produce large amount of powder
Generally speaking, in order to makeRaymond mill produce large amount of powder and high output in the production process, there are the following requirements
1. Scientific and reasonable collocation
When Raymond pulverizer works, on the one hand, it is necessary to consider whether the selection of equipment model can meet the daily production demand and avoid equipment overload work. On the other hand, in the selection of materials, try to select materials with moderate hardness, which are more suitable for Raymond pulverizer, so as to prevent excessive hardness of materials, which is difficult to realize pulverizing operation and blocking at the discharge port, resulting in difficult powder discharge.
2. Regular maintenance
After Raymond pulverizer is used for a period of time, it shall be overhauled, and vulnerable parts such as grinding roller, grinding ring and blade shall be overhauled and replaced. The connecting bolts and nuts of the grinding roller device shall be carefully checked before and after use to see whether there is looseness and whether the lubricating grease is sufficient. In addition, when the grinding roller device is used for more than 500 hours to replace the grinding roller again, All rolling bearings in the roll sleeve must be cleaned, and the damaged parts shall be replaced in time.
To sum up, it is about the abnormal powder discharge of Raymond mill and the solutions. However, for more information about the detailed equipment of Raymond mill, you are welcome to consult online for free .
