適用範囲

This standard applies to the safety requirements of various crushing equipment, including jaw crushers, cone crushers, gyratory crushers, vertical impact crushers, impact crushers, hammer crushers, ring hammer crushers, and roll crushers. It is mandatory for manufacturers designing and producing these machines for the Chinese market. The standard covers hazards during the entire lifecycle of the equipment as defined in GB/T 15706.1.

技術要求

The standard specifies general safety requirements based on ergonomic principles to reduce operator fatigue and avoid sharp edges. Equipment must maintain stability during operation and provide sufficient space for operation and maintenance. Pressure piping and hoses must be pressure-resistant, with high-pressure systems clearly marked, as referenced in GB/T 15706.2. For operating positions, the standard mandates protection against falling materials and requires proper visibility and access. Main operator cabins must adhere to strict limits for noise, vibration, and dust concentration. Control systems must include a master stop switch and emergency stop devices at each operating position, complying with GB/T 16855.1 and GB 16754. Moving parts, especially in impact crushers and hammer crushers, must have robust protective guards to prevent ejection of materials or rotating elements. Feeding openings must be equipped with auxiliary devices to prevent blockages, and specific protocols must be followed when clearing jams. Maintenance procedures require power disconnection and warning signs, with special attention to preventing sudden rotor movement. Electrical equipment must feature ground fault protection, with explosion-proof requirements for hazardous environments per GB 3836.1. Hydraulic systems must not exceed maximum allowable pressure and require monitoring devices for temperature and pressure. Work platforms, lighting, and fire prevention measures must meet specific structural and material safety criteria.

試験方法

The standard outlines specific testing methods for evaluating operator safety. Noise measurement at the operator's position must be conducted according to GB/T 13325. Vibration testing for operator seats follows the methods specified in GB/T 8419. Additionally, dust concentration in the operator's cabin is measured using methods outlined in the Metallurgical Enterprise Dust Measurement Method.

よくある質問

What types of crushers are covered under GB 18452-2001?
