Scope
This document specifies the safety requirements for the design and manufacture of the following model-face granulators: — Underwater granulators; — Water-ring granulators; — Dry granulators; — Centrifugal granulators; — Roller-knife granulators. This document applies to all major hazards, dangerous states, and dangerous events related to model-face granulators that may arise during their entire life cycle (see GB/T 15706—2012, Section 5.4), during their intended use, and in cases of misuse that can be reasonably foreseen by the manufacturer (see Appendix A). This document does not apply to draw-wire granulators. This document does not include design requirements for exhaust ventilation systems.
