Safety red line for crushing operations: core procedures that operators must comply with

The crushing operation is a combination of heavy machinery, high-speed rotation, high-altitude blanking and high dust environment, which is extremely dangerous. To ensure safety, a series of core procedures must be elevated to an insurmountable "safety red line" and internalized into the instinctive reaction of every operator. These regulations are the summary of countless lessons. Violation of any of them may directly lead to serious personal injury or even death.

Article 1: When the equipment is running, it is strictly prohibited to touch any moving parts. This is the iron law of iron laws. When the crusher, belt conveyor and vibrating screen are in operation, it is strictly prohibited to perform any of the following actions:

Touch, clean, adjust or lubricate rotating pulleys, flywheels, couplings, drive shafts with hands, feet, tools or any object.

Insert any part of your body or tools into the crushing cavity, feed port, or discharge port.

Standing or crossing under or near a running belt or chain, it is strictly prohibited to clean or cross the belt while it is running.

Try to deal with the clogged inlet or outlet directly with your hands or a hook.

Article 2: Strictly implement the maintenance system of "stop, power off, tag out, and lock". Whenever the equipment is inspected, cleaned, maintained, repaired or troubleshooted, the following complete process must be followed:

Complete shutdown: Stop the equipment completely.

Cut off and lock the power supply: Not only must the switch be turned off, but the main power supply must also be cut off, and an eye-catching "No closing is allowed when someone is working" warning sign is hung on the switch. It is best to use a personal lock to ensure that the equipment cannot be accidentally started by others.

Wait for energy to be released: For systems with hydraulic or pneumatic pressure, confirm that the pressure has been completely released.

After completing the above steps, you can start working.

Article 3: Wear and use personal protective equipment correctly. This is the last barrier to protect yourself. Entering the work area must always:

Wear a safety helmet to protect your head from falling rocks.

Wear a dust mask or face shield to reduce dust inhalation.

Wear tight-fitting work clothes to prevent getting caught in rotating parts.

Wear anti-smash and anti-puncture protective shoes to protect your feet.

Use protective gloves, goggles, or earplugs as needed.

Article 4: Standard start-up, inspection and feeding procedures.

Sequential startup: The equipment must be started in the "reverse flow" sequence, that is, the final product conveyor belt at the end is started first, then forward in sequence, and finally the crushing host is started. Ensure that materials have a clear output path. The sequence is reversed during shutdown.

No-load start: After starting up, let the equipment run idling for 1-2 minutes, and then start feeding materials evenly and continuously after confirming that there are no abnormal sounds or vibrations. It is strictly prohibited to start with load.

Super-capacity feeding is prohibited: It is strictly prohibited to input oversized and super-hard materials that exceed the processing capacity of the equipment, or to input too many materials at one time to cause blockage or overload.

Article 5: Keep the site tidy and keep safe passages clear.

Clean up spilled materials and oil stains promptly to prevent slipping.

Tools and spare parts should be placed at fixed points and must not hinder access and operation.

Make sure that all safety shields and guardrails are intact and installed in place. It is strictly prohibited to remove or move them without permission.

Be familiar with and confirm the location of the emergency stop button and be able to reach it quickly.

The last and most important protocol: foster a safety culture of mutual reminders and proactive reporting. Everyone has the right to refuse illegal instructions, and everyone has the responsibility to stop other people's unsafe behavior. Silence about hidden dangers is condoning accidents. Safety is not a slogan posted on the wall, but a habit woven into the blood and awe engraved in the heart. Every safe operation is the most responsible performance for yourself, your family, and your team.
