BS EN 1009-3-2020 pdf free download.Machines for mechanical processing of minerals and similar solid materials – Safety Part 3: Specific requirements for crushing and milling 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 crushing and milling machinery for the mechanical processing in quarrying, recycling and processing mineral and by-products.
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 part of EN 1009 are different from those which are stated in EN 1009-1:2020, the requirements of this part of EN 1009 take precedence over the requirements of EN 1009-1:2020 for machines that have been designed and built according to the provisions of this part of EN 1009.
This document, together with EN 1009-1:2020, deals with all the significant hazards, hazardous situations and events relevant to crushing and milling 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 crushing and milling machinery which are manufactured before the date of publication of this document by CEN.

NOTE Annex A shows examples of crushing and milling machinery.
3.1 crusher
machine intended for reducing the size of mineral-based material to particles of smaller dimension starting from coarse size to millimetric size and which can be based on various crushing technology
3.2 mill
machine intended for reducing the size of minerals based material to particles of smaller dimensions starting from middle coarse size to micronic size, and which can be based on various grinding technologies
3.3 jaw crusher
compression crushing machine consisting of a fixed jaw and a movable jaw which moves so as to increase and decrease the gap between the two jaws
[SOURCE: ISO 11375:1998, 3.2.1]
3.4 gyratory crusher
cone crusher
compression crushing machine consisting of a moving part rotated eccentrically within the fixed part;
both moving and fixed parts are in a form of truncated cones
[SOURCE: ISO 11375:1998, 3.2.2]
3.5 roll crusher
crushing machine which breaks
a) by pressure being continuously maintained between the faces of two revolving cylinders (rolls);
b) by impact, shear and pressure between one roll which has, at intervals rows of teeth and another roll or breaker plate [SOURCE: ISO 11375:1998, 3.2.3].BS EN 1009-3 pdf download.
