Aperçu de conformité

Cet aperçu n’est actuellement disponible qu’en anglais.

Champ d’application

This standard applies to mineral processing equipment, including classification, magnetic separation, flotation, gravity separation, and dewatering equipment. It covers safety requirements during the lifecycle of the machinery but excludes general mechanical, electrical, hydraulic, and pneumatic hazards covered by other standards. This standard is mandatory for all manufacturers of mineral processing equipment entering the Chinese market.

Exigences techniques

The standard outlines a comprehensive list of hazards associated with mineral processing equipment and specifies safety requirements and measures to mitigate them. Key areas include general safety measures aligned with ergonomic principles, protection against contact with hot/cold surfaces, and ensuring adequate operational and maintenance space. It mandates specific requirements for operation positions, such as providing operator cabins in harsh environments, ensuring noise levels do not exceed 85dB(A), and maintaining dust concentrations below 2mg/m3. Control systems must comply with GB/T 16855.1, featuring emergency stop devices and automatic alarms. Manufacturers must ensure that all moving parts are properly guarded and that filter presses with high-speed filter plates are equipped with photoelectric protection. The standard also details requirements for stability, electrical equipment, and hydraulic systems. Equipment must be securely anchored, electrical components must be grounded and protected in hazardous environments, and hydraulic systems must include pressure and temperature monitoring. Furthermore, it provides extensive guidelines for installation, operation, maintenance, and the design of platforms and access ways, referencing standards like GB 17888.2 and GB 4053.

Méthodes d’essai

Testing and verification methods referenced in the standard include noise measurement at the operator's position according to GB/T 13325, vibration evaluation of operator seats via GB/T 8419, and dust concentration measurement in the workplace using GB/T 5748. These ensure compliance with the specified environmental and safety limits.
