Rollers series PL/PLF - Where used?
In conveyors used to transport very corrosive materials; and where difficult
working conditions prevail: the extraction industries and in the mining of salt, chemical
industries, fertiliser manufacture and in marine environments which require corrosion resistant
rollers.
These rollers demonstrate particular resistance to the presence of high humidity and water,
and also to corrosive elements present in the environment or in the conveyed material itself.
The design of the rollers utilises plastic materials for the most critical parts, which,
excellently and economically, substitute for traditional materials such as stainless steel,
bronze and aluminium.
Testing and actual plant trials have well demonstrated the efficiency and versality of
these rollers. The characteristics designed into them provide a long working life even
in the most severe environment, and when one considers their low purchasing and maintenance
cost, PL/PLF rollers provide the ideal solution for severe applications.
The functioning temperatures recommended are:
-10°C to +50°C for rollers with PVC end caps
-10°C to +70°C for rollers with steel end caps.
