What factors will cause the fan current of the Raymond mill to be too high?

Everyone should be very clear. A complete set of Raymond mill system consists of three parts: the main machine, the analysis machine and the fan. In the Raymond mill control system, you need to pay attention to the situation of these three motors, so that you can work on the equipment grinding work. To understanding. Recently, some customers have called to consult, what is the reason for the high current of the Raymond mill fan? This kind of problem can not be considered from one side, and should be combined with the entire Raymond mill system for investigation.
First, check whether the lower air duct is blocked. After passing the qualified fine powder of the analysis machine, it is necessary to go through the pipeline, enter the powder collector, and finally obtain the finished product. When the machine is turned on and off, the fine powder will precipitate due to the absence of wind. Therefore, during normal operation, a small amount of fine powder will be deposited through the curve. After a long time, the fine powder of the air duct will accumulate. Especially in the corner part, it is easy to cause the phenomenon of blockage. At this time, the fan will generate heat, and the current of the fan motor will rise. It requires a timely volume, and it is necessary to check whether the air passage is excessively fine. The corresponding solution.
Secondly, the Raymond mill feeds fast, which also causes the feed to block the material. At this time, the blockage will cause circulating wind in the main engine and the pipe. On the one hand, the function of the grinding roller and the grinding ring in the main machine is seriously consumed. If the wind does not go up, it will cause the fan current to rise, and it needs to be stopped for inspection.
Finally, check whether the fan belt of the Raymond mill is loose. At the same time, the driving mode of the fan is that the motor is driven by the belt. When the belt feeds, the wind will be insufficient. If there is not enough air volume, the material is difficult to be blown up. It will also rise, and more attention is needed at this time. If not handled, it will affect the output of the equipment.
The above is a brief introduction to the high current of the Raymond mill fan. If you want to know more about this, you can do detailed consultation online.
