Problems solved by technology

[0004] However, the lubricating oils used in the existing vertical mill roller bearings and rotary kiln tugboat bearings are conventional mineral-based industrial oil products. These conventional mineral-based industrial oils have excellent high temperature resistance, but their anti-foam performance is not good.

Abstract

The invention belongs to the technical field of lubricating compositions characterized by using mixtures of high molecular and non-high-molecular compounds as additives, and specifically relates to alubricating composition for a grinding roller bearing of a vertical mill and a tug wheel bearing of a rotary kiln. The lubricating composition is prepared from the following ingredients: synthetic oil, a bearing oil composite additive, an antirust agent, a metal deactivator and an anti-friction agent. The lubricating composition has excellent wear resistance, emulsification resistance and foam resistance.

Description

technical field [0001] The invention belongs to the technical field of lubricating compositions characterized by a mixture of polymer and non-macromolecular compounds as additives, in particular to a lubricating composition for vertical mill roller bearings and rotary kiln tugboat bearings. Background technique [0002] my country is a big country in cement production and consumption, and its production and consumption have ranked first in the world for 20 consecutive years, and have reached more than 50% of the world's total for a long time. From 1981 to 2015, China's cement consumption increased sharply from 82.08 million tons to 2,348 million tons. At present, there are more than 5,000 cement production enterprises in my country, with about 600,000 employees, which occupy a pivotal position in my country's national economy ("Analysis on the Evolution Trend of China's Cement Production Carbon Emission Intensity Based on the Bottom-up Method", Cao Zhi et al., Resource Scien...
