What is butter? "Butter" is a traditional old name, and its true scientific name is lubricating grease (hereinafter referred to as butter). Unlike lubricating oil, butter is in the form of a paste and can be divided into nine grades based on cone penetration (viscosity), represented by 000-6 #. The larger the grade, the thicker it is. The most commonly used grades are 2 #, 3 #, 0 #, and 00 #. The main function of butter is that a certain type of butter relies on its own characteristics to provide long-term lubrication and protection, extending the service life of mechanical bearings.
Butter has a wide range of uses, and should be used wherever there is mechanical friction. Many people have asked online "What kind of butter is good for crushers?" Enthusiastic netizens have replied as follows: "Generally, lithium based butter is used in crushers. If you want to save money, you can also use calcium based butter, but this type of butter is sensitive to temperature changes." As a professional butter worker for many years, I have two suggestions for this answer. This enthusiastic netizen's answer is also correct, and my suggestion is:
1. Calcium based butter has been phased out for a long time, and this netizen also said that this type of butter is sensitive to temperature changes, but not resistant to high temperatures. For today's high production manufacturing industry, when equipment starts running, the temperature of bearings will quickly rise. This type of butter has little effect, and using this type of butter for crushers will only make the bearings break down faster. Therefore, even to save money, it is not advisable to buy products that have already been phased out.
2. Speaking of lithium based butter, it is recommended that people do not seek cheap prices and buy inferior products. Nowadays, there are many lithium based butter products with added talcum powder in the market because they are cheap, half the price of standard lithium based butter. Behind this cheap price, the product quality will definitely change, and you get what you pay for. Everyone understands this principle, but many people just like cheap things. Our laboratory has conducted various performance tests on this cheap lithium based butter. After testing, it was found that this lithium based butter with added talcum powder does not have anti-wear and extreme pressure performance (four ball test), which is a very important performance. On the contrary, it does not. Which type of mechanical bearing will operate without load? A type of butter without extreme pressure will only cause bearing damage faster. For example, the normal service life of a crusher bearing was originally 1000 hours, but using butter without extreme pressure shortened the bearing life to 400 hours or less. At this time, you may think it is a bearing quality problem, but the fundamental reason is that there is a problem with the butter used.
In addition, the bearing load varies greatly. Standard lithium based butter can be used for small crushers used for crushing feed, traditional Chinese medicine, and grains. However, lithium based butter is no longer suitable for crushing stones, stones, or other hard objects in mines. In this case, it is necessary to choose butter that is resistant to high temperatures, has good wear resistance, and has good sealing properties, such as molybdenum disulfide butter and extreme pressure composite lithium based butter. Shandong Jinbaoshan Machinery Co., Ltd. provides you with specialized oil for mining crushers. If you cannot buy it in the market or are not confident, you can purchase original specialized butter provided by professional crushers manufacturers.
