Maintenance and Upgrading Strategies for Key Components of Powder Production Equipment

In the powder production process, equipment such as extruders, cooling belts, mills and mixers play a key role, and good maintenance and timely upgrading of the key components of these equipment are essential to ensure efficient and stable production.

The key components of an extruder include the screw, the heating system and the head. Wear and deformation of the screw will affect the extrusion effect and quality of the material, so it needs to be inspected and repaired regularly. The stability of the heating system is directly related to the plasticizing effect of the material. Regular cleaning and maintenance of the heating elements will ensure uniform temperature control. The design and wear of the machine head will affect the shape and dimensional accuracy of the extrudate.

The key components of a cooling belt are the die, the pressure regulating system and the feeding device. The accuracy and wear of the die determines the quality and shape of the tablets, and regular replacement of a badly worn die ensures good pressing results. The accuracy and stability of the pressure regulating system plays a key role in the density and hardness of the tablets and requires regular calibration and maintenance. The smooth operation of the feeding device ensures that the material enters the die uniformly.

The key components of the mill are the grinding disk, the grinding rollers and the classifying device. Wear and tear of the grinding disk and rollers will reduce the grinding efficiency and powder fineness, timely replacement or repair can maintain good grinding effect. The precision of the grading device determines the particle size distribution of the powder, regular inspection and adjustment can ensure that the powder size meets the requirements.

The key components of the mixer are stirring paddle, transmission device and sealing parts. The shape and rotation speed of the mixing paddle affect the uniformity of mixing, and regular inspection of the wear and deformation of the paddle will help to improve the mixing effect. The stability of the drive ensures continuous mixing, and regular maintenance and lubrication can reduce the occurrence of malfunctions. The integrity of the sealing parts prevents material leakage and the entry of external impurities, which need to be inspected and replaced regularly.

In terms of maintenance strategy, making a detailed maintenance plan is the basis. According to the operating time, work load and environmental conditions of the equipment, determine a reasonable maintenance cycle and specific content. Establish an equipment maintenance file to record the situation of each maintenance, the problems found and the treatment measures, so as to provide reference for the follow-up maintenance and fault diagnosis.

For the upgrading of equipment, it should be combined with production demand and technological development. For example, the traditional mechanical transmission is upgraded to a more efficient hydraulic transmission or electrical transmission to improve the operational stability and precision of the equipment. For the classification device of the mill, more advanced airflow classification technology can be used to improve the precision of powder particle size control.

When upgrading components, give full consideration to the overall compatibility and performance optimization of the equipment. At the same time, keep close communication with equipment manufacturers to understand the latest technology and upgrade program to ensure the feasibility and effectiveness of the upgrade.

In conclusion, for the powder production equipment including extruder, cooling belt, milling machine and mixer, scientific maintenance and reasonable upgrade of key components is an important measure to ensure smooth production and improve product quality and production efficiency.
