Safety of machinery - Safety requirements for the design and construction of paper making and finishing machines - Part 4: Pulpers and their loading facilities

This European Standard applies to pulpers and their loading facilities intended for use in paper making and
shall be used together with EN 1034-1:2000. It deals with all significant hazards, hazardous situations and
hazard events relevant to pulpers and their loading facilities, when they are used as intended and under the
conditions foreseen by the manufacturer (see clause 4).
This European Standard is not applicable to pulpers and their loading facilities that have been manufactured

EN ISO 12100-1:2003 and the following terms and definitions apply. 3.1
pulper

machine that dissolves raw materials such as wood pulp, pulp, recovery stock and waste paper to form a pumpable defibrated stock suspension to be used for the production of paper and board. Pulpers may be designed either as rotor pulpers, see 3.2, or as drum pulpers, see 3.3 3.2

rotor pulper pulper consisting of a tank and a power-driven rotor to break down the charged raw material using water. The principle of a rotor pulper is illustrated in Figure 1 3.3

drum pulper pulper consisting of a horizontal drum rotating round its horizontal axis in which raw material is dissolved with the addition of water. The principle of a drum pulper is illustrated in Figure 2 3.4 loading facility machinery such as continuous conveyor, lifting device or a combination of these machines intended to charge pulpers with the raw material to be dissolved such as pulp, waste paper or recovery stock 3.5 feeding conveyor continuous conveyor as part of the loading facility defined in 3.4 onto which the raw material to be dissolved is loaded by means of fork lifts, mechanical shovels or lifting tools, see Figure 1 3.6 charging conveyor continuous conveyor as part of the loading facility defined in 3.4, forwarding the raw material to be dissolved into the pulper, see Figure 1
