Safety operation procedures and precautions for mixers

As an indispensable equipment in many industries such as construction, chemical industry, and food, the safe operation of mixers is directly related to production efficiency and the life safety of workers. In order to ensure the safe and efficient operation of mixers, this safety operation procedure and precautions are specially formulated. All operators are requested to strictly abide by them.

Professional training before operation

1. All personnel who intend to operate mixers must receive safety operation training provided by professional institutions or senior technicians.
2. The training content should include the structural principle, operating procedures, emergency shutdown methods, common troubleshooting and preventive measures of the mixer.
3. Operators must pass the training assessment and obtain a certificate of qualification before they can start work.

Wearing protective equipment

1. Before operation, personal protective equipment must be worn, including but not limited to safety helmets, protective glasses, earplugs, protective gloves and work clothes.
2. Ensure that the protective equipment meets national safety standards and has no obvious damage, and can effectively protect the safety of operators.

Inspection before equipment operation

1. Check whether the power circuit of the mixer is intact and not exposed or damaged.
2. Confirm that the mixing blades, transmission devices, protective covers and other components are firmly installed and not loose.
3. Check whether the lubricating oil, coolant, etc. are sufficient to ensure that the equipment is in good lubrication.
4. Empty the foreign matter in the mixing barrel to avoid damage or accidents during startup.

Do not reach into the mixing area

1. During the operation of the mixer, it is strictly forbidden for any person to put his hand or other objects into the mixing area to prevent accidents such as pinching and strangulation.
2. If you need to observe the mixing situation, you should do it through the observation window or after stopping the machine.

Pay attention to abnormal equipment operation

1. During the operation, pay close attention to the operating status of the mixer. If abnormal sounds, vibrations, overheating, etc. are found, stop the machine immediately for inspection.
2. Be familiar with the common fault alarm signals of the mixer. Once an alarm occurs, take measures to deal with it immediately, and contact maintenance personnel if necessary.

Clean the equipment and cut off the power supply

1. After using the mixer, it needs to be thoroughly cleaned to remove residual materials and dirt.
2. Before cleaning, the power supply must be cut off and a "No Closing" warning sign must be hung to ensure that the equipment is completely powered off.
3. Use special tools for cleaning to avoid scratching the mixing barrel or blades with hard metal objects.

Inspection and maintenance after shutdown

1. After each shutdown, the mixer should be fully inspected, including whether the fasteners are loose, whether the transmission parts are worn, and whether the electrical components are intact.
2. According to the equipment maintenance manual, regular maintenance work such as lubrication and replacement of wear parts should be performed to ensure that the equipment is in good condition for a long time.

Comply with environmental protection and safety laws

1. Operators should strictly abide by national and local laws and regulations on environmental protection and production safety, and shall not illegally discharge waste or perform dangerous operations.
2. Noise, dust and other pollution generated during the use of the mixer should be effectively controlled to meet environmental protection requirements.
3. Regularly test the environmental performance of the mixer to ensure that emissions meet standards.

In short, the safe operating procedures and precautions of the mixer are an important basis for ensuring production safety and increasing the service life of the equipment. All operators should always bear in mind the principle of safety first, strictly abide by these regulations, and jointly create a safe and efficient working environment.
