Installation, Commissioning, Maintenance and Upkeep of 20L Double Planetary Mixer [Technical Version]

The planetary mixer is mainly used for mixing high-viscosity chemical materials. Its main unit adopts a planetary gear reducer design, featuring low noise and high mechanical efficiency, which can save power consumption and reduce equipment space occupation.This machine is suitable for mixing, reacting, dispersing, dissolving, conditioning and other processes of multi-component solid-solid, solid-liquid and liquid-liquid materials required in chemical, light industry, food, battery, pharmaceutical, building materials, pesticide and other industries. It is applicable to the preparation of various high-viscosity substances such as inks, pigments, adhesives, sealants, potting compounds, ointments, pasty materials, lubricating greases, paints, creamy cosmetics and additives. The applicable viscosity range is approximately 10,000～1,000,000 CP.The form of the agitator can be multi-layer paddle type, frame type, butterfly type, outer wheel type, etc., according to material requirements. During the operation of the planetary mixer, relevant procedures must be followed to extend its service life.

Basic Operation and Maintenance of 20L Double Planetary Mixer

After completing all preparation work, connect the power supply and start working as required.The operating components include the main pot mixing system, main pot homogenizing system, main pot lifting system, auxiliary pot mixing system and vacuum pump system. Control is performed through the buttons on the panel, which can control the on/off of the lighting lamp, the operation of the main pot mixing, the operation of the main pot dispersion, the operation of the vacuum pump and the heating of the main and auxiliary pots. All controls are carried out on the control panel.Refer to the control panel schematic diagram.

4.2 Filling Operation:

a. The filling speed is adjusted by the hydraulic station throttle valve according to the material viscosity.b. The filling volume is adjusted by setting the time on the control panel.c. The lift button controls the continuous rise of the oil cylinder.

4.3 Precautions

4.3.1 Do not operate mixing or dispersion with the cover open.

4.3.2 Do not raise the pot cover too high. When reaching the upper limit or closing the cover, jog and observe simultaneously to ensure safety.

4.3.3 The power supply ground wire must be reliably grounded to ensure electrical safety.

4.3.4 The equipment power supply must be cut off before any maintenance or cleaning.

4.3.5 Never put hands into the pot or touch any operating components during equipment operation to prevent accidents.

4.3.6 If any abnormal noise is detected during operation, stop immediately and restart only after identifying and resolving the cause.

5.1 Connect the power supply (ensure the power supply matches the equipment requirements) and confirm the ground wire is reliably grounded. Turn on the main power switch, and the power indicator light will illuminate.

5.2 Connect each pipeline of the pot and the water inlet pipe (directly connect tap water to the water inlet), which shall be prepared by the user.

5.3 Use the jog mode to lift the upper cover. After confirming normal operation, lift it to the highest point. When reaching the upper limit of the travel switch, the travel switch will click, and the lifting shall stop automatically.

5.4 Before vacuuming, check that the pot is closely attached to the pot cover, and that the pot mouth, material inlet cover, etc., are tightly closed with reliable sealing. Close all valve interfaces on the pot cover, then open the vacuum valve on the pot cover, and start the vacuum pump to draw vacuum. After reaching the required vacuum level, turn off the vacuum pump (see the operation guide for detailed function description) and close the vacuum valve simultaneously.

5.5 For dispersion cutting and scraper mixing: first add materials (water can be used as a substitute), then turn on the corresponding control switches to adjust the dispersion cutting speed and scraper mixing speed respectively. The rotation direction of the dispersion disc is counterclockwise when facing the cutting wheel; the rotation direction of the agitator is counterclockwise when facing the agitator (viewed from bottom to top). During commissioning, perform jog test operation, and start the homogenizer formally only after confirmation. Before starting the agitator, jog it to check for any abnormalities in the stirring and wall scraping. If any, eliminate them immediately.

5.6 To open the pot cover and material inlet cover, ensure there is no vacuum pressure in the pot. If there is vacuum pressure in the pot, close the valve on the vacuum interface (and turn off the vacuum pump), then open the valve on the pot cover to release the vacuum pressure.

5.7 The vacuum pump can only be started when the homogenizing pot is sealed. If it is necessary to start the pump with atmospheric exposure for special reasons, the operation time shall not exceed 3 minutes.

5.8 The vacuum pump is strictly prohibited from running without oil; do not block the exhaust port during pump operation. Before turning off the vacuum pump button, must first open the vent valve on the vacuum pipeline (to ensure normal pressure in the pipeline and prevent vacuum pump oil from flowing back into the pipeline).

5.9 Regularly check the lubricating oil and grease in various components and bearings, and replace them with clean lubricating oil and grease in a timely manner (high-temperature resistant lubricating grease is recommended).

5.10 Keep the stirring paddle and dispersion disc clean. After each use or when changing materials, clean the parts of the stirring paddle and dispersion disc that come into contact with the working fluid. After the flanges of the pot body and pot cover are relatively fixed, confirm that the rotation direction of the stirring paddle motor is correct and there are no other abnormalities before starting operation.

5.11 The cleaning of all pots shall be handled by the user in accordance with standards (it is recommended to keep the equipment clean regularly. If the equipment is to be shut down for a long time, clean it immediately after shutdown).
