1、 Daily inspection and cleaning

• Visual inspection
  • Check the bodyBefore and after each use, check the mixer body for cracks, deformation, or damage, especially in the mixing chamber, mixing blade, and cover. If any abnormalities are found, the machine should be stopped immediately and professional personnel should be contacted for repair.
  • Fastener inspectionCheck whether the bolts, nuts, and other fasteners of each component are loose. If they are loose, they should be tightened in a timely manner to prevent the equipment from loosening due to vibration during operation and causing safety accidents.
• Clean the mixing room
  • Residual material cleaningAfter each use, residual materials in the mixing chamber should be promptly cleaned to prevent material clumping or deterioration that may affect the next use. For materials that are prone to adhesion, specialized cleaning tools such as scrapers, brushes, etc. can be used to remove the material.
  • Avoid corrosionIf the mixed materials are corrosive, the mixing chamber should be rinsed with clean water and wiped dry after cleaning to prevent residual corrosive substances from damaging the equipment.
• Cleaning of mixing blade
  • Remove attachmentsThe stirring blade is a component that comes into direct contact with the material and is prone to material adhesion. Regularly clean the attachments on the mixing blade to ensure its balance and normal operation. You can use a soft cloth or brush dipped in an appropriate amount of cleaning agent to wipe.
  • Check for wear and tearCheck whether the blades of the mixing blade are worn, deformed, or broken. If the wear is severe, it will affect the mixing effect and the mixing blade needs to be replaced in a timely manner.

2、 Lubrication and maintenance

• Bearing lubrication
  • Regularly refuelBearings are key components of high-speed mixers and require regular addition of lubricating grease to ensure their normal operation. According to the frequency of use and environmental conditions of the equipment, lubricating grease should generally be added every 200-500 hours of operation. When adding lubricating grease, pay attention to the appropriate amount and avoid too much or too little.
  • Choose appropriate lubricating greaseLubricating grease suitable for high-speed operation and high-temperature environments, such as lithium based grease, should be selected. The performance of different types of lubricating grease varies. Before use, carefully read the equipment manual and choose the appropriate lubricating grease.
• Lubrication of transmission components
  • Chain and gear lubricationFor mixers that use chain or gear transmission, it is necessary to regularly check the tension of the chain and the meshing of the gears, and add an appropriate amount of lubricating oil. Loose or tight chains can affect transmission efficiency and equipment lifespan, and poor lubrication of gears can lead to increased wear.
  • lubrication intervalGenerally, the chain and gears need to be lubricated every 100-200 hours of operation. Lubricating oil should be selected from products with good anti-wear and anti-oxidation properties.

3、 Electrical system maintenance

• Motor inspection
  • Temperature and vibration monitoringRegularly check the operating temperature and vibration of the motor. Excessive motor temperature may be caused by excessive load, poor ventilation, or motor failure, while abnormal vibration may be due to damaged motor bearings or improper installation. If any abnormalities are found, the machine should be stopped in a timely manner for inspection and handling.
  • Insulation performance testingRegularly check the insulation resistance of the motor using a megohmmeter to ensure good insulation performance of the motor. Low insulation resistance may cause motor leakage and lead to safety accidents. The insulation resistance of a general motor should not be less than 0.5 megohms.
• Electrical component inspection
  • Contactors and relaysCheck whether the contacts of electrical components such as contactors and relays are in good contact and whether there is any burning phenomenon. Poor contact of the contacts can cause the equipment to fail to start or operate stably, and severely eroded contacts need to be replaced in a timely manner.
  • Line inspectionCheck whether the electrical circuit is damaged, aged, or loose. Damaged circuits may cause short circuits or leakage, the insulation performance of aging circuits may decrease, and loose circuits may cause poor contact. If any problems are found, they should be repaired or replaced in a timely manner.

4、 Regular maintenance and calibration

• Seal inspection and replacement
  • Sealing performance inspectionRegularly inspect the sealing components of the mixer, such as shaft seals, gaskets, etc., to ensure good sealing performance. Damaged seals can lead to material leakage, resulting in material waste and potential environmental pollution.
  • replacement cycleDetermine a reasonable replacement cycle based on the usage of the seal and the manufacturer's recommendations. Generally speaking, the shaft seal needs to be replaced every 1000-2000 hours of operation, and the sealing gasket can be checked and replaced regularly according to the actual situation.
• speed calibration
  • Ensure accurate rotational speedThe speed of the high-speed mixer has a significant impact on the mixing effect, and a tachometer should be used regularly to calibrate the speed of the stirring blade to ensure that it meets the process requirements. Excessive or insufficient rotational speed can affect the mixing quality and production efficiency.
  • adjustment methodIf the speed deviation is large, it is necessary to check the transmission system, such as whether the belt is loose, whether the frequency converter parameters are correct, etc., and make corresponding adjustments.
• Safety device inspection
  • Limit switch and emergency stop buttonCheck if the safety devices of the mixer, such as limit switches and emergency stop buttons, are working properly. Limit switches can prevent equipment from running beyond its travel limit, and emergency stop buttons can quickly stop equipment operation in emergency situations, ensuring the safety of operators.
  • Testing and MaintenanceRegularly test the functionality of safety devices, such as pressing the emergency stop button, and observe whether the equipment can immediately stop running. If the safety device fails, it should be repaired or replaced in a timely manner.

5、 Long term shutdown maintenance

• rust prevention treatment
  • Apply rust inhibitorIf the high-speed mixer needs to be stopped for a long time, the metal surface of the equipment should be treated with rust prevention. A layer of anti rust oil or anti rust paint can be applied, especially to parts that are prone to rust such as mixing chambers, mixing blades, and transmission components.
  • Coverage protectionCover the equipment with plastic film or dust cover to prevent dust and moisture from entering the interior of the equipment.
• Regularly start
  • Prevent components from getting stuckEquipment that has been out of use for a long time should be restarted at regular intervals (such as one month) to allow the equipment to run without load for a period of time, in order to prevent components such as bearings and gears from rusting or getting stuck due to long-term inactivity.

6、 Maintain records and archive management

• Establish and maintain records
  • Detailed record informationEstablish a comprehensive maintenance record file, detailing the time, content, replaced parts, discovered problems, and handling methods of each maintenance. For example, record the time and quantity of each lubricant addition, the date and model of seal replacement, etc.
  • Easy to trace and analyzeMaintenance records help analyze the operational status and maintenance needs of equipment, providing reference for future maintenance work.
• Archives Management
  • Properly preserve dataProperly store maintenance records and archives, and also archive technical information such as equipment manuals and drawings for easy reference during maintenance and upkeep.
