Overview

EN 1034-22:2005+A1:2009 is a CEN European standard specifying safety requirements for the design and construction of wood grinders used to produce pulp for paper making. It covers wood grinders (including sharpening devices) used as intended and under manufacturer‑foreseen conditions, and is to be used together with EN 1034-1:2000+A1:2010 (common requirements). The standard addresses all significant hazards relevant to these machines, but excludes loading facilities and hazards caused by overpressure (for which pressure‑vessel directives apply). It is not applicable to wood grinders manufactured before its publication.

Key Topics and Requirements

This standard focuses on practical machine safety and hazard mitigation. Key topics include:

• Risk assessment and scope

  • Designed as a C‑type standard (takes precedence over conflicting A/B standards where applicable).
  • Covers hazards identified by EN 1050 risk assessment methodology.

• Mechanical safety and guarding

  • Safeguarding of power transmission elements (grinding stone drives, gate valves, sharpeners).
  • Prevention of crushing, drawing‑in and trapping hazards (fixed guards, safety distances per EN 294 / EN 953).

• Feeding systems

  • Preferential use of continuous feeding conveyors to avoid manual feeding.
  • Means to detect/avoid log jams and overloading (e.g., photoelectric sensors, weighing devices).

• Gate valves and press grinders

  • Requirements to avoid crushing points and prevent unintentional start‑up (lockable isolation, depressurization).
  • Inspection hole/manhole design to prevent bursting-covers that allow controlled pressure equalization.

• Thermal, noise and ergonomic safety

  • Protection against ejection of hot pulp, hot surfaces, and noise exposure (refer to EN 563 and EN 13023).
  • Integrated lighting, access design, and ergonomic principles for operators.

• Control and emergency systems

  • Emergency stop, start‑up warnings, isolation to prevent unexpected start‑up, and maintenance/repair provisions.
  • Electrical, hydraulic and high‑pressure cleaning device requirements.

• Verification & information

  • Clause on verification of safety measures and mandatory user information and documentation.

Applications and Who Uses It

EN 1034-22 is intended for:

• Machine designers and manufacturers of wood grinders and related pulp production equipment.
• Safety engineers and compliance officers in pulp & paper mills implementing new grinders or retrofitting existing equipment (post‑publication).
• Plant managers and maintenance teams responsible for safe operation, guarding, and servicing.
• Notified bodies and certification authorities assessing compliance with EU machinery directives.

Practical use includes design validation, risk reduction, machine commissioning, and preparing technical documentation required for regulatory compliance.
