Abstract

The invention relates to special lubricating oil for a grinding roller of a vertical mill and a manufacturing method of the special lubricating oil. The special lubricating oil is prepared by taking synthetic oil as base oil, adding a variety of efficient compound additives and refining, and the special lubricating oil can fastest repair abrasion, reduce abrasion and avoid dry friction and high-temperature coking. The product is widely applied to mining, metallurgy, electric power, chemical engineering, cement and other industries for being used on vertical mills, has the advantages of good viscosity-temperature property, strong extreme pressure abrasion resistance, thermal stability, no coking at high temperature and the like, is further relatively cheap, environment-friendly and safe, and can fundamentally solve the problem that the vertical mill has a failure due to poor lubrication.

Description

technical field [0001] The invention relates to the technical field of lubricating oil manufacturing, in particular to a special lubricating oil for vertical mill rollers and a manufacturing method thereof, which is a special lubricating oil for vertical mill rollers with high load and low speed in industries such as cement, electric power, metallurgy, and chemical industry . Background technique [0002] The vertical mill is one of the most important equipment in the pulverizing system of various industrial and mining enterprises. It is an operating equipment that integrates crushing, drying, and conveying. Due to its advantages such as low energy consumption, high efficiency, relatively small footprint, light weight, large grain size, strong drying capacity, long life of wearing parts, and low noise, the new dry process production line is developing rapidly today. , Metallurgy, mining, chemical industry, cement and many other fields have gradually eliminated the old tube ...
