  First, what oil does the mill lubricating oil use?

  A: Mill lubricants usually use industrial lubricants.

  Coal mills usually use lubricating oil to lubricate various mechanical parts to reduce friction and wear and to ensure the normal operation of the equipment. The type of oil selected for the mill is usually based on the recommendations and requirements of the equipment manufacturer and the application environment. There are several types of lubricating oil used in coal mills.

  1. Industrial lubricating oil

  Industrial lubricants include a variety of different types of lubricants, such as greases and lubricants. You can choose the right industrial lubricants for your specific equipment and operating conditions. Coal mills typically use industrial lubricants to lubricate bearings, gears, seals and other mechanical parts.

  2, grease

  Grease is a semi-solid lubricant commonly used to lubricate bearings and other lubrication points. Its high viscosity is suitable for use in high load, high temperature or polluted environment.

  3. Hydraulic oil

  If the mill uses a hydraulic system to drive certain components, you will also need to choose a hydraulic oil suitable for the hydraulic system. Hydraulic fluids need to have appropriate viscosity and anti-wear characteristics to ensure the normal operation of the system.

  4. High temperature lubricating oil

  If the mill is operating in a high temperature environment, you may need to choose a lubricant with high temperature tolerance to ensure that it still provides effective lubrication under high temperature conditions.

  5. Low temperature lubricating oil

  If the mill is operating in a low temperature environment, you may need to choose a lubricant with low temperature flow to ensure good lubrication performance in low temperature conditions.

  Lubricants can be selected according to the recommendations and specifications provided by the equipment manufacturer. Manufacturers typically provide specific lubrication requirements for their equipment, including the type of lubricant, viscosity class, and replacement interval. Ensuring the use of lubricants that meet these requirements can extend the life of the equipment and ensure its proper operation. If a manufacturer's recommendation is not available, you can consult a professional lubrication engineer or supplier for advice on selecting lubricants.

  Second, what are the phenomena of low oil pressure of coal mill? What are the ways to deal with it?

  1, the lubricating oil pressure indicator is low: there is usually a lubricating oil pressure indicator on the coal mill, which is used to show the lubricating oil pressure. If the indicator shows low oil pressure, this is a clear sign.

  2, abnormal noise of mechanical parts: when the oil pressure is insufficient, the mechanical parts may produce abnormal noise, indicating insufficient lubrication.

  3, friction and wear increase: insufficient lubricating oil will lead to increased friction and wear between mechanical parts. This can result in equipment failure and damage to components.

  4. Unstable operation of the equipment: insufficient lubricating oil pressure may lead to unstable operation of the mill, including unstable speed or smooth operation.

  5, temperature rise: due to increased friction, insufficient lubrication may lead to a rise in the temperature of mechanical parts.

  The way you deal with low oil pressure depends on the root cause of the problem. Here are some possible ways to deal with it:

  1, check the lubrication system: First, check all components of the lubrication system, including pumps, filters, pipes, valves and oil tanks. Look for any leaking, damaged, or blocked parts and repair or replace them.

  2, check the lubricating oil level: ensure that there is enough hydraulic oil in the hydraulic tank. If the oil level is too low, add enough hydraulic oil, but do not exceed the oil level limit of the equipment.

  3, check the hydraulic pump: the hydraulic pump may have problems, such as pump damage or suction line obstruction. Check the status and performance of hydraulic pumps and repair or replace faulty pumps.

  4. Replace lubricating oil: If the lubricating oil is aging or contaminated, it may be necessary to replace fresh lubricating oil. Ensure that the appropriate type and grade of lubricants are used according to the equipment specifications.

  5, maintenance and cleaning: regular equipment maintenance and cleaning to ensure the normal operation of the lubrication system. This includes cleaning filters, checking pipes and hydraulic cylinders, replacing seals, and more.

  6, adjust the hydraulic system: adjust the pressure and flow of the hydraulic system as needed to ensure that the lubrication requirements of the equipment are met.

  If you are unsure of the cause of the problem or how to deal with low oil pressure issues, you can seek advice and repair services from a professional lubrication engineer or equipment manufacturer. It is very important to solve low oil pressure problems in a timely manner to prevent equipment failure and damage to components.

  Third, the role of the mill lubricating oil pump

  The mill lubrication pump is one of the key components in the hydraulic system, and its role is to transport the lubricating oil from the oil tank to the mechanical parts that need lubrication to ensure that the friction between these parts is reduced, the wear is reduced, and the normal operation of the equipment is ensured. The following is the main role of the mill lubricating oil pump.

  1, lubrication: various moving parts in the mill, such as bearings, gears, seals and pistons, need lubrication to reduce friction and wear. The lubrication pump pumps the lubricating oil by pumping it between these parts to form a lubricating film to ensure that they can work smoothly and efficiently during movement.

  2, cooling: the lubrication pump can also conduct heat in the hydraulic system to help control the temperature of the system. This is very important to prevent the hydraulic system from overheating. By delivering lubricating oil to the working parts, it helps to cool these parts and absorb heat.

  3, sealing: In some cases, the lubrication pump is also used to form a hydraulic seal to ensure that the liquid in the hydraulic system does not leak. These seals are usually achieved by pressing lubricating oil into the sealing parts, thus ensuring the effectiveness of the seal.

  4, increase the pressure of lubricating oil: lubricating oil pump can increase the pressure of lubricating oil to meet the needs of different lubrication points. This is important to ensure that the lubricating oil can reach parts far from the tank.

  5, ensure the continuity of the lubrication system: the lubricating oil pump continues to supply the lubricating oil to the hydraulic system to ensure that the system always has the required amount of lubricating oil. This helps prevent the lubrication system from drying out or being under-lubricated.

  The main function of the lubricating oil pump is to provide lubricating oil to the hydraulic system to ensure the normal operation of lubrication, cooling, sealing and working pressure between the mechanical components. This helps to extend the life of the equipment, reduce maintenance costs, and ensure the operation of the equipment.
