Screw
conveyors concerning ATEX directive 94/9 CE
This directive found application on machinery
and give protection systems in order to be used in potential
explosive atmosphere.
Explosive atmosphere means mixture, doing in atmospheric
conditions, air with inflammable substances on gas state,
vapour, fogs or powders, after primer, combustion propagates
together with mixture not burnt as potential as explosive
atmosphere means atmosphere susceptible to be trasformated
in explosive zone caused by local and operative condition.
Regarding this directive will be done difference for machinery
groups and classes.
II machinery group touches machinery destined to be used
on different zones, putting them in dangerous and explosive
zone.
Screw conveyor had been classified on this II group.
Machinery and protection systems must be designed and realized
considering technological knowledge regarding protection
against explosions, in order to use them for all the time
for seen on safety code. Near Fansider plant, we plan and
realize screw conveyors, classified to be used on plants
as zone as safety 20-21-22(see here with certificate).
Therefore, at the end, together with machinery, customer
will receive relative identification tag released by certification
institute (authority certificate), in order to apply it on
machinery with specific symbol, belonging group and class
required for certification.
