21、 ISO 12100“. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this t

22、ype C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. BS EN 13389:2005+A1:2009EN 13389:2005+A1:2009 (E) 5 1 Scope !This European Standard specifies requirements for the design, tr

23、ansport, installation, operation and maintenance of batch production fixed or tilting horizontal bowl type mixers with one or two rotating shafts with or without movable blades. These mixers are used to mix, knead and homogenise food for animal or human consumption in powder, paste or liquid form. T

24、he mixers can be floor mounted or transportable (with or without castors). They are intended to be used when stationary.“ These machines are used in feed mills and factories which produce, work on or process foodstuff, for example biscuits, bread, chocolate, cereal products. This European Standard d

25、oes not deal with the use of the machine in potentially explosive atmospheres. !This European Standard deals with the significant hazards, hazardous situations and events relevant to mixers with horizontal shafts, when they are used as intended and under conditions of misuse which are reasonably for

26、eseeable by the manufacturer (see Clause 4).“ This European Standard also specifies food hygiene requirements. The feeding equipment, the dosing equipment, and the requirements of equipment for the supply of inert gases, and for heating and cooling, are excluded from the scope of this European Stand

27、ard. The hazards due to the unloading equipment (container, discharge belt, etc.) are not dealt with in this European Standard. When drafting this European Standard, it has been assumed that the machines are not intended to be cleaned with a water jet. This European Standard is not applicable to mix

28、ers with horizontal shafts which are manufactured before the date of publication of this European Standard by CEN. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.

41、izontal shafts used to mix the product 3.1.4 movable blade(s) knife (knifes) fixed inside the bowl 3.1.5 side cutter mixing device independently driven from the main drive shaft(s) 3.2 Mode of operation and normal operational use The range of machines covered by this European Standard are designed t

42、o batch mix powdered, paste and liquid products, the primary ingredient usually being flour. When the mixing bowl is in its loading position, the machine receives the dry or wet ingredients, weighted or metered. This operation is controlled by either the operator of the machine or automatically. The

43、 machine mixes and/or melts ingredients during a time or with an energy based measurement. When the mixing cycle is over, the product is unloaded into a mobile container, or into a fixed hopper or onto a discharge belt, e. g. by tilting the mixing bowl. The machine may be manually operated or comple

44、tely automatic. The bowl may be heated or cooled. 3.3 Description Typical mixers with horizontal shafts are shown in Figures 1a and 1b, with the following main elements: a) rigid machine frame; b) mixing bowl; c) rotating mixing shafts; d) main drive motor and gearbox; e) bowl tilting mechanism; f)

45、electrical controls; g) delivery device: discharge hopper, discharge belt or mobile container; h) movable blades if any.

46、gnificant hazards 4.1 General This clause contains all the significant hazards, hazardous situations and events, as far as they are dealt with in this European Standard, identified by risk assessment as significant for this type of machinery and which require action to eliminate or reduce the risk.

47、BS EN 13389:2005+A1:2009EN 13389:2005+A1:2009 (E) 9 Before using this European Standard it is important to carry out a risk assessment of the mixer with horizontal shafts to check that it has the hazards identified in this clause. 4.2 Mechanical hazards The significant mechanical hazards are: a) tra

48、pping points between the blades and the bowl; b) trapping points between the bowl and machine frame during tilting of the bowl on tilting bowl machines; c) trapping points between the mixer bowl and cover; d) drive mechanisms; e) loss of stability. The example shown in Figure 2 illustrates 6 danger

49、zones associated with these hazards: Zone 1: Access to the rotating tools through the feed opening: hazards of trapping and shearing, between blades and bowl, to the whole or any part of the body; Zone 2: Access to the rotating tools through the discharge: hazards of trapping and shearing, between blades and bowl, to the whole or any part of the body; Zone 3: Access to trapping point between the bowl and machine frame on machines with tilting bowl
