lubrication and maintenance of grinding mill for mining machinery For heavy machinery, especially for industrial grinding mill, under the condition of high-speed operation, the lubrication and maintenance of core components is very important. Correct lubrication and maintenance will greatly prolong the service life of the machine and improve the working efficiency. Now let's introduce the knowledge of lubrication and maintenance of the grinding mill. 1. What is the role of lubrication? The role of lubrication is to reduce friction, reduce loss and improve equipment efficiency and equipment maintenance measures. 2. What are the components of the grease? It is composed of base oil, thickener, stabilizer and additive. 3. What kinds of lubrication are classified according to different working surfaces and working conditions? It is divided into hydrodynamic lubrication, boundary lubrication and semi liquid film lubrication. 4. What are the types of lubricants according to their viscosity grades? It can be divided into light, medium and heavy quality. 5. Which three concepts are usually used to represent the viscosity temperature characteristics of lubricating oil? Viscosity index, viscosity ratio, viscosity temperature coefficient 6. What is solid lubricant? What are the categories? Solid lubricant is the use of solid powder, film or composite materials as lubricating materials. It can be divided into four categories: soft metals, metal compounds, nonmetal and other inorganic substances and organic substances.
7. What are the two types of lubrication methods and devices according to the form of lubrication points supplied by lubricants? It is divided into separate lubrication and centralized lubrication. 8. What is oil mist lubrication? What are the advantages? Oil mist lubrication is to transfer the oil flow into mist and disperse it to the lubrication parts through the oil mist lubrication equipment. Its advantages are that it can receive any good effect, and can emit a lot of heat on the friction pair, reduce the working temperature, take away the wear debris and small dust particles, and reduce the oil consumption. 9. What factors should be considered when selecting grease? Temperature, speed, load and environment should be considered. Grinding Mill: https://www.sbmchina.com/products/grinding-mill.html
