What issues should be considered when using a grinding mill in a flour production line during the summer?

After prolonged operation, grinding mill equipment in a flour milling production line will inevitably experience some problems. Here are some common issues that grinding mills are prone to encounter in the high temperatures of summer:

In the hot summer, bearing overheating is a common phenomenon when grinding mills operate under high temperatures. However, this overheating is often overlooked, but it can actually be caused by a variety of factors, such as prolonged continuous operation, poor lubrication, and bearing wear. Overheating of bearings not only affects the machine's performance and efficiency, but if not addressed promptly, it can also lead to bearing damage and even more serious malfunctions.

Therefore, when overheating of the grinding mill bearings is detected, operators should take immediate action, such as stopping the machine for inspection, replenishing lubricating oil, and cleaning the heat sink, to ensure timely cooling of the bearings. This not only effectively extends the bearing's service life but also prevents other malfunctions caused by bearing damage, thereby ensuring the stable operation and production efficiency of the grinding mill.

Besides high temperature and continuous operation, impurities inside the bearings are also a key factor causing overheating. The presence of impurities hinders the smooth operation of the bearings, leading to overheating and even wear, severely affecting their service life. Furthermore, the use of lubricating oil needs to be just right. Too much or too little lubricating oil will cause the bearing to overheat, thus affecting its normal operation. Therefore, we should pay close attention to these issues to ensure that the bearings operate in a clean and well-lubricated environment to extend their service life and improve equipment efficiency. Bearing maintenance and upkeep are crucial.

The hot and rainy characteristics of summer cause the grinding mill to experience tangential airflow from the bottom of the grinding ring, passing through the grinding zone between the grinding rollers and the grinding ring. The three grinding rollers mounted on the spider frame not only revolve around the central axis but also rotate due to friction. When the material temperature or humidity is too high, it can easily cause the spider frame to malfunction, severely impacting production progress.
