(Amendment)Machines for mechanical processing of minerals and similar solid materials - Safety - Part 4: Specific requirements for screening machinery
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.
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 prEN 1009-6 "Specific requirements for mobile and semi mobile equipment" is under preparation to cover specific requirements (e.g. mobility, braking, access, frequent transportation), including exceptions and additional requirements for mobile and semi 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.

10 Modification to 4.2.4.1, “General”
Replace the paragraph and NOTE with the following:
"If it is necessary to enter inside the screen for inspection and maintenance between decks in lying or
crawling position, in exemption to EN 1009-1:2020+A1:—, 4.2.1, the following subclauses 4.2.4.2 and
4.2.4.3 apply.
NOTE If there are space constraints in an existing plant, replacement of a screen is considered as a spare part
replacement and therefore does not need to meet this requirement. Other solutions are possible, e.g. removing
components to the top deck, see 4.2.1.".
11 Modifications to 4.2.4.2, “Passage from the top to work inside”
Second paragraph, remove the words "replacement or" to read: "The distance between two decks under
cross beam shall be 550 mm, except for upgrade on an existing plant due to space constraints, this
minimum distance (H2) may be 450 mm."
Add, at the end of the text:
"NOTE 450 mm is the very minimum value defined by the health and safety organization. In case of upgrade due
to space constrain, if 450 mm is not possible to comply with, other solutions are possible, e.g. removing components
to the top deck, see 4.2.1."
12 Modification to 4.2.4.3.2, “Punctual obstacle inside the screen”
Add, after the second paragraph:
"NOTE 450 mm is the very minimum value defined by the health and safety organization. In case of upgrade due

“Reducing handling operations and down time shall be foreseen at the design stage considering the
following: …”
First paragraph, replace the second indent with the following:
"— if the distance between the roof cover and the upper deck is less than the values specified in 4.2.2.2
