As high-speed rotating mechanical equipment, the safety of plastic crushers is always the top priority of the industry. In 2025, with the improvement of occupational health and safety standards globally, the safety norms for plastic machinery have also ushered in a comprehensive upgrade. For enterprises, compliance is not only a legal obligation but also respect for the life of every employee.
Multiple Safety Interlock Protection
The new generation of crushers has achieved "zero tolerance" in safety design. The most core improvement lies in the multiple safety interlock system. When the hopper or screen bracket of the crusher is opened, the safety switch will immediately cut off the main motor power and forcibly lock the rotor to prevent the equipment from starting accidentally. The machine can only be restarted when all protective parts are fully closed in place.
In addition, emergency stop buttons are installed at easy-to-reach positions on the machine to ensure that operators can cut off power in the first instance in an emergency. For large shredders, they are also equipped with hydraulic system pressure loss protection and oil temperature alarm functions to prevent safety accidents caused by system failures.
Anti-splash and Anti-noise Design
Material splashing during crushing is a major cause of eye and facial injuries. The 2025 standard requires that the crusher feed inlet must be equipped with anti-splash curtains or baffles, and the design must comply with ergonomics, which is convenient for feeding and can effectively block rebounding fragments. For applications with large dust, negative pressure dust removal systems have become standard, which not only protects employees' respiratory health but also reduces the risk of dust explosion.
Noise is also an invisible safety hazard. Long-term exposure to high noise can cause hearing damage. Modern silent crushers control the working noise within a safe range (usually below 80 decibels) through a combination of fully enclosed soundproof enclosures, double-layer soundproof glass, and sound-absorbing cotton, creating a healthy working environment for employees.
Intelligent Safety Monitoring
AI technology is also being introduced into safety management. Intelligent cameras can monitor the feeding area in real-time. Once it detects that the operator's arm or other body parts enter the dangerous area, the system will trigger a shutdown mechanism in milliseconds. This active safety protection raises accident prevention from "human defense" to a new height of "technical defense".
Xiaoma Machinery always regards safety as the bottom line of design. We ensure that every piece of equipment undergoes strict safety testing before leaving the factory and complies with international safety standards such as CE. Because we believe that only safe equipment can create lasting value for customers.
