Machines for mechanical processing of minerals and similar solid materials - Safety - Part 4: Specific requirements for screening machinery

This document, to be used together with EN 1009-1:2020, specifies the safety requirements and their verification for the design and construction of screening machinery for the mechanical processing in quarrying, recycling and processing mineral and by-products as defined in 3.1.
In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer.
When requirements of this document are different from those which are stated in EN 1009-1:2020, the requirements of this document take precedence over the requirements of EN 1009-1:2020 for machines that have been designed and built according to the provisions of this document.
This document, together with EN 1009-1:2020, deals with all the significant hazards, hazardous situations and events relevant to screening machinery when they are used as intended and under the conditions foreseen by the manufacturer (see Annex C).
This document does not cover:
-   design relating to road traffic regulations;
-   hazards arising from the use of the machines in potentially explosive atmospheres as well as from processing of explosive materials and risks related to electromagnetic compatibility;
-   specific hazards related to mobile machinery;
-   fully or partially self-evolving behaviour or logic;
-   collaborative applications;
-   network connection communication.
NOTE 1   EN ISO 13766-1 and EN ISO 13766-2 specify test methods and acceptance criteria for evaluating the electromagnetic compatibility of all kinds of mobile construction machinery.
NOTE 2   EN 1009-6 "Specific requirements for mobile machinery: (under preparation) covers specific requirements (e.g. mobility, braking, access, frequent transportation), including exceptions and additional requirements for mobile equipment. This means that mobile machines are not covered as long as EN 1009-6 is not published by CEN.
This document is not applicable to screening machinery which are manufactured before the date of publication of this document by CEN.

Overview

EN 1009-4:2020/FprA1 - Part 4 of the CEN series on machines for mechanical processing of minerals - provides specific safety requirements for screening machinery (screening machines) used in quarrying, recycling and mineral/by‑product processing. It is intended to be used together with EN 1009-1:2020 (now referenced as EN 1009-1:2020+A1) and covers design, construction and verification of safety measures, plus the manufacturer’s information on safe working practices and residual risks. The amendment draft (prA1) updates access, inspection and maintenance provisions and adds pictorial and rotary‑screen requirements.

Key topics and requirements

• Scope and precedence: Where this Part differs from EN 1009-1, the specific requirements here take precedence for machines designed to this Part. The standard does not cover road traffic design, explosive atmospheres, EMC, specific mobile‑machine hazards (until EN 1009‑6 is published), or network communication features.
• Inspection and maintenance access: Detailed dimensions and ergonomics for access openings and reach distances are specified (examples from Annex C):
  • Horizontal two‑arm openings: minimum 645 mm × 221 mm; maximum H = 1 520 mm.
  • Single‑arm inspection reach: maximum 495 mm.
  • Typical maintenance reach (mid‑range grip): 506 mm.
  • Minimum deck clearance where entry is needed: normally 550 mm, with 450 mm as an absolute minimum for upgrades in existing plants (with alternative solutions recommended where 450 mm cannot be met).
• Design for safe replacement and service: Roof covers may need to be dismountable and operable within force limits specified in EN 1009‑1. Rotary screens requiring drum rotation for screen change must provide controlled movement (e.g., hold‑to‑run mode or manual auxiliary drive).
• Information and pictorials: Manufacturers must provide safe‑working information (including residual risks) and pictorial warnings for rotary drums to prevent entry.
• Annex C (informative): Provides calculation rationale and ergonomic considerations, referencing EN/ISO anthropometric and reach standards.

Applications and users

• Who uses it: OEMs and designers of screening machinery, safety and compliance engineers, maintenance planners, plant owners/operators in quarrying, recycling and mineral processing, and conformity assessment bodies.
• Practical value:
  • Ensures safer machine design and serviceability.
  • Guides specification and procurement to meet harmonized CEN safety expectations.
  • Supports risk assessments, CE technical documentation and maintenance procedures.
  • In retrofit scenarios, clarifies minimum exemptions and alternative safety solutions.

Related standards

• EN 1009-1:2020 / EN 1009-1:2020+A1 - General safety requirements for machines in this series.
• EN 547 and ISO 7250 series - anthropometric and reach data used for access calculations.
• EN ISO 13766 series (EMC testing) - referenced for mobile machinery electromagnetic compatibility (not covered here).
• EN 1009-6 (under preparation) - will cover specific mobile machinery requirements when published.
