Safety Precautions and Preventive Measures in Crushing Operations

Safety Precautions and Preventive Measures in Crushing Operations

Crushing operations involve heavy rotating machinery, falling materials from heights, high-speed flying rocks, and large amounts of dust, making it a high-risk production activity. Ensuring its safety requires a systematic and standardized operating procedure and proactive risk awareness from all personnel. The core of safety management is integrating preventive measures into every link, every position, and every individual's behavior, with the goal of achieving "zero accidents."

The primary safety precautions and preventive measures lie in personnel behavior norms and on-site safety management. All operators, especially machine operators and maintenance personnel, must undergo rigorous safety training and be familiar with equipment hazard zones and emergency response procedures. During operation, safety helmets, dust masks (or face shields), close-fitting work clothes, safety shoes with anti-smash and anti-puncture protection, and protective gloves must be worn correctly at all times. The most crucial rule is: when the equipment is running, no one is allowed to inspect, clean, adjust, or repair rotating or moving parts (such as pulleys, flywheels, and rotors), and it is strictly forbidden to touch the running belt with hands or tools. Sufficient safety distances for operation and inspection must be established around the equipment, and conspicuous safety warning signs must be displayed. Before entering areas such as the crushing chamber or below the hopper, the "lockout/tagout" procedure must be implemented to ensure that the equipment is completely stopped and cannot be accidentally started.

Secondly, the equipment operation process and operating status must be strictly controlled. Starting the equipment must follow a strict sequence, usually "reverse-flow startup," that is, starting the final product conveyor belt first, then sequentially moving forward, and finally starting the crushing machine, ensuring a smooth output path for the materials. Stopping the machine is the opposite: first stop the feeding and crushing machine, and after all the material in the machine and on the belt has been discharged, then stop the downstream equipment sequentially. Feeding must be uniform and continuous, and must not exceed the equipment's processing capacity to prevent blockage or overload. During operation, the equipment's sound, vibration, and ammeter readings must be constantly monitored. If abnormal noise, severe vibration, or sudden current changes are detected, the machine must be stopped immediately for inspection. At the same time, dust control measures must be implemented, such as activating sprinklers or dust collectors, to reduce the risk of dust explosions and harm to personnel health.

Finally, establishing effective emergency preparedness and a continuous safety culture is a solid foundation for risk prevention. The site must be equipped with qualified first-aid kits, eyewash facilities, and fire-fighting equipment, and all personnel must be familiar with their location and usage. Emergency response plans for mechanical injuries, electric shocks, material collapses, and dust hazards must be developed and regularly practiced. During equipment maintenance, safe and reliable support devices must be used to prevent accidental falling of components. More importantly, a safety culture of mutual supervision and proactive reporting of hazards should be fostered within the team, and safety reviews should be conducted regularly. Internalizing safety regulations into everyone's instincts and habits, making caution a reflex, is the most fundamental guarantee for preventing risks and achieving long-term safe production. Safety is not a burden, but the most important investment in life and productivity.
