3 Definitions
For the purposes of this standard the following definitions apply:
3.1
internal mixer
A mixing machine for the discontinuous production of rubber or plastic compounds. Its main parts are (Figure
1):
two counter rotating horizontal rotors (a) within a mixing chamber (b);
a feed hopper (c) with several openings:-
at the feed side, a feed opening equipped with a door (hopper front door) (d);
at the side opposite to the feed side, an inspection/access opening (hopper rear opening) equipped
with a fixed or moveable guard (hopper rear door) (e);
possible additional feed openings for connection to feeding ducts (f);
a floating weight which applies pressure to the materials to be mixed (g);
a drop type or sliding type discharge door (h).
Figure 1 — Principal parts of an internal mixer
3.2
ancillary equipment
Equipment which interacts with the internal mixer. For the purposes of this standard this includes upstream
and downstream equipment. Examples: belt conveyors, bin tippers, powder or liquid feeding systems, two-roll
mills, extruders.
3.3
major cleaning
a cleaning operation which requires suspension of production, the mixer to be emptied and access to the
mixing chamber
4 List of hazards
4.1 Mechanical hazards
The significant mechanical hazards which are specifically associated with internal mixers are described in
4.1.1 to 4.1.6; the significant mechanical hazards which are not specifically associated with internal mixers are
described in 4.1.7 and 4.1.8. The mechanical hazards associated with major cleaning, maintenance and repair
operations are included in 4.8.
