Cement mill main bearing lubrication and management
The main bearing of the cement mill is the most critical component of the entire machine, so when we use it, we need to pay more attention to its lubrication and management, which directly affects its safe and reliable operation.
First of all, it is necessary to check and clean the bearing during the routine maintenance of the cement mill. When the oil groove and the oil hole of the bearing are full, the oil should be added to the appropriate height of the bearing, generally the oil level should be 0.2-0.3 mm higher than the center line of the bearing surface. Generally, the main bearing of the cement mill adopts the grease lubrication. Use the grease gun to inject grease after the bearing is pre-filled with butter. The daily butter injection amount should be about 50-70g for every 380ml butter groove.
In the process of using the cement mill, the temperature rise of the bearing shall not exceed 35°C, otherwise it will cause premature bearing failure and shorten its service life. For the temperature rise of the main bearing of the cement mill, we must pay close attention to it. If the temperature rise of the bearing is too high, we should take timely measures to stop the machine, and make sure that the bearing It rotates at a low speed until it runs at a temperature below the normal temperature, then it can be operated normally.
At the same time, the use of clean fuel is also an important way to ensure the lubrication performance of the bearing. The cleanliness of the lubricant is related to the service life of the bearing, and the fuel used must meet the “GB/T 5157-1995 petroleum products” Level 2 or high grade requirements to ensure the normal operation of the bearing and the cement mill.
In summary, lubrication and management of the main bearing of the cement mill is an important means to ensure the normal operation and service life of the cement mill. In addition to the reasonable choice of lubricant, timely and correct supplement of lubricant, low speed operation of the bearing under high temperature, etc., the routine inspection and maintenance of the bearing should also be done.
In a word, the lubrication and management of the main bearing of the cement mill can not be ignored. Reasonable lubrication and management are the prerequisite of the safety and reliability of the equipment operation, which needs the attention and maintenance of the operator.
