28、r accessories intended to be used in sausage kitchens and industrial operations. This European Standard deals with all significant hazards, hazardous situations and events relevant to mixing machines, when they are used as intended and under the conditions foreseen by the manufacturer ( see Clause 4
29、). This European standard is not applicable to mixing machines which are manufactured before the date of publication of this European Standard by CEN. 1.2 This European Standard covers the following types of mixing machines: Mixing machines with a tilting container, one or several mixing shafts Mixi
30、ng machines with a stationary mixing container, front face or bottom discharge opening Mixing machines with a container and loading device Mixing machines with a container, mixing shaft(s), screw conveyor and loading device The mixing machines are constructed of a machine frame, a trough-shaped mixi
31、ng container, one or several mixing shafts, an associated drive and electrical, hydraulic and pneumatic components, depending on machine type. The mixing shaft can be equipped with wings, screws, rods, paddles or the like. Mixing machines may be equipped e. g. with cover over the top of the mixing c
32、ontainer, pipe connections for gases, steam, water or vacuum, protective hood over the front face discharge opening, lifting devices for mixing shaft, loading device, screw conveyor at the discharge opening.

34、 into the mixing container by hand or by means of a loading device and mixed by the mixing unit. The discharge outlet may be located at the bottom or the front face and can either be a slide, a flap, a pipe, a pump or a screw. During the production of this standard the following assumptions were mad
35、e: Mixing machines are installed at a sufficiently lighted place. They are used only by designated and skilled operators. Although it should be advised against, the standard, taking into account practice, deals with the hazards due to cleaning with pressurised water. 2 Normative references The follo
