Compliance overview
Scope and applicability
This standard is applicable to various types of mineral processing feeders, including plate, belt, chain, reciprocating, disc, screw, scraper, and vibrating feeders. It specifies safety requirements from physical performance and intended use perspectives. This standard is mandatory for all manufacturers of mineral feeding equipment entering the Chinese market. It does not cover general mechanical, electrical, hydraulic, or pneumatic hazards already addressed in GB/T 15706.1 and GB/T 15706.2.
Technical requirements
The standard outlines a comprehensive list of 29 potential hazards during the equipment's lifecycle, including crushing, shearing, electrical shocks, and fire. It mandates that safety measures align with ergonomic principles to reduce operator fatigue and prevent injuries from sharp edges or hot surfaces. Manufacturers must ensure adequate operational and maintenance space around the feeders. For operator positions, the standard requires protection against dust, noise, and material projection. Main operator cabins must not exceed specific noise limits (85dB(A)) and must be equipped with air purification systems to maintain dust concentrations below 2mg/m³. Control systems must feature emergency stop devices at every operating position and comply with GB/T 16855.1 for safety-related parts. The standard also details requirements for moving parts protection, requiring guards for rotating and transmission components, especially eccentric blocks of inertial vibrators. Electrical equipment must have reliable grounding and comply with GB 5226.1, while hydraulic and lubrication systems must include temperature or pressure monitoring devices to prevent hazards from leaks or overpressure. Additionally, it specifies requirements for installation and maintenance, emphasizing that maintenance work should be performed during shutdowns. If maintenance must be done while operating, strict safety protocols, including dual-person monitoring and accessible emergency stops, are mandated. Fire prevention measures require fire-resistant materials in operator cabins and the placement of portable fire extinguishers.
Testing methods
Testing and verification primarily involve checking compliance with referenced standards. Noise measurement at the operator position must be conducted according to GB/T 13325. Vibration testing for operator seats follows the methods specified in GB/T 8419. Dust concentration in the operator cabin is measured using the procedures outlined in GB/T 5748.
FAQs
What products are regulated under GB 25519-2010?
GB 25519-2010 regulates mineral processing feeders, specifically plate, belt, chain, reciprocating, disc, screw, scraper, and vibrating feeders used to continuously and uniformly feed materials to processing equipment.
Is GB 25519-2010 a mandatory standard?
Yes, except for Chapter 3 (which is recommended), the rest of the standard is mandatory. Manufacturers must comply with these safety requirements to sell their equipment in China.
What are the key safety requirements for operator cabins under this standard?
Operator cabins must protect against dust, noise, and material projection. Key limits include a maximum noise level of 85dB(A), dust concentration not exceeding 2mg/m³, and vibration acceleration not exceeding 1.25m/s². Cabins must also be made of fire-resistant materials.
