Conveyor system having a conveyor belt
The invention relates to a conveyor system, comprising a conveyor belt, which has a carrying-side cover plate ( 3 ) and a running-side cover plate ( 4 ), and comprising drums, supporting rollers, and supporting frames, wherein the conveyor system forms a material-conveying upper run having a feed point for the conveying material and a mostly material-free lower run. For a further sufficient flame-inhibiting effect that does not negatively affect the further physical properties of the conveyor belt and that does not pose a health hazard to persons, animals, or the environment, the carrying-side (carrying side) cover plate ( 3 ) and/or the running-side (running side) cover plate ( 4 ) contains at least one flameproofing agent, wherein the flameproofing agent is free of bromium and bromium compounds.
1. A conveyor system comprising:
a conveyor belt comprising a first outer sheet disposed on a loadbearing side and a second outer sheet disposed on a drive side;
a plurality of drums;
a plurality of loadbearing rollers; and,
a plurality of supportive structures;
wherein the conveyor system forms a material-conveying upper web with an application site for material to be conveyed;
wherein the conveyor system forms a substantially material-free lower web;
wherein one or more of the first outer sheet on the loadbearing side, or the second outer sheet on the drive side, comprises at least a first flame retardant and a second flame retardant;
wherein the first one flame retardant is zinc hydroxystannate, zinc hydroxystannate, or a combination of zinc hydroxystannate and zinc stannate;
wherein the second flame retardant comprises antimony, an antimony compound, or a combination of antimony and an antimony compound, provided the second flame retardant is an antimony-trioxide-free flame retardant;
and,
wherein the first flame retardant and the second flame retardant are free from bromine and bromine compounds.
2. The conveyor system as claimed in claim 1 , wherein the second flame retardant is incorporated in an amount of from 0 to 5 phr.
