High Ultrafine Mill Control System

High Ultrafine Mill Control System

How can I have a good high ultrafine mill control system?

Summary of contents: The control system of the ultrafine mill (pictured) is crucial. The action of the human body is mainly controlled by the central nervous system and the brain. The operation of the ultrafine mill is mainly controlled by the control system. Including electrical systems, pneumatic systems, electronic control parts.

The control system of the ultrafine mill is very important. The action of the human body is mainly controlled by the central nervous system and the brain. The operation of the ultrafine mill is mainly operated and controlled by the control system, which mainly includes the electrical system and the pneumatic system. Electronic control section.

The control system of the ultrafine mill must reach the reasonable arrangement of the pipeline, the quality of the components is guaranteed, there is no logic error of the program, and each part is interlocked, each step should be guaranteed, so that there is a good Control system.

Machining accuracy is undoubtedly a key link. High-ultrafine mills have many components and complex mechanical structures, covering a wide range of knowledge. The coordination of various systems is critical. Uniform feeding and start-stop time, sensitive roll size adjustment and clutch action, automatic feeding flexibility, stable rolling distance, etc. These all involve the precision of machining, and parts requiring high precision must be refined. Fine work, especially the accuracy of the feeding parts and the structural parts of the rolling system, must be in accordance with the processing accuracy of hydraulic components or pneumatic components.

For the components of the control system, the functions of the mechanical structural components must be reliable, the rotating components must be flexible, and the fixed components must be fixed in order to make the control system sensitive. The common faults of the components of the ultrafine mill and their causes are as follows:

  1. 1. Suspension shaft components. Usually, after the ultrafine mill is disintegrated, the sliding bearing of the suspension shaft is found to be locked. There is a large amount of sludge in the suspension shaft cavity. The reason is that the air outlet gap is too large, and the air pressure in the inner cavity of the suspension shaft is smaller than the air pressure in the milling chamber, so that the dust is dusty. Enter the suspension shaft cavity.
  2. 2. Milling chamber. After the machine is turned off to open the grinding chamber, the roller is found to be rotated when the roller is turned, and the roller and the grinding ring are collapsed. The analysis is caused by poor lubrication of the roller bearing.
  3. 3. Lubricate the pump. Lubrication pump pressure is less than 550kPa (normal pressure is 550 ~ 890kPa), the possible reasons are: (1) the bevel gear box has leakage; (2) the check valve has reverse flow; (3) the lubrication pump itself has excessive valve core wear. If the pressure is higher than 890kPa, the reasons may be: (1) oil level observation and release oil mark hole blockage; (2) pressure check valve can not pass oil, may be completely blocked or the valve core is stuck; (3) lubrication pump valve The core is clogged, affecting normal oil delivery.
  4. 4. Wear of the rollers and grinding rings. The main cause of wear is the poor quality of the rollers.
  5. 5. The suspension shaft oil chamber is connected to the air duct for wear. The reason is mainly caused by the continuous scouring of the powder in the grinding chamber of the ultrafine mill.
  6. 6. The mixing plough is worn. The mixing of the mixing plough by the dust is the main reason for the deformation of the mixing plough.
