Description

Technical Field

[0001] The utility model relates to the technical field of lubricating grease grinding, in particular to a lubricating grease multi-stage grinding device. Background Art

[0002] Grease is a viscous, oily semisolid used in mechanical friction parts to lubricate and seal. It is also used on metal surfaces to fill gaps and prevent rust. It is mainly made of mineral oil and thickeners. According to the thickener, it can be divided into soap-based grease and non-soap-based grease. The thickeners of soap-based greases are commonly metals such as lithium, sodium, aluminum, and zinc, and metal soaps such as potassium, barium, lead, and manganese are also used. The vast majority of greases are used for lubrication and are called anti-friction greases. They mainly reduce mechanical friction and prevent mechanical wear. They also take into account the protective and sealing effects of metal corrosion. The working principle of grease is that the thickener keeps the oil in the position where lubrication is needed. When there is a load, the thickener releases the oil, thereby playing a lubricating role.

[0003] When grease is in use, the metal particles contained inside will cause wear to the mechanical parts that need to use the grease. The diameter of the metal particles contained in the thickener must be smaller than a certain value. Traditional grinding devices are mostly single grinding settings and cannot grind the grease multiple times. Secondly, when the grinding device is grinding the grease, the time the grease stays in the primary grinding bin and the secondary grinding bin cannot be controlled, and it cannot ensure that the grease can be ground to a large extent and reduce the diameter of the metal particles inside the grease. Therefore, a multi-stage grinding device for grease is proposed to address the above problems. Utility Model Content
