Ref:- British Standards BS 2890 and BS 5934
The BSI has decided to undertake the drafting of a new standard for troughed belt conveyors which will effectively replace the above two standards.
The scope of the new proposed standard is :-
This British Standard specifies the mechanical design, dimensional requirements and methods for calculating the operating power requirements for non-mobile troughed belt conveyors incorporating carrying idlers. The standard also specifies methods for calculating the forces exerted on the belt by the idlers and other mechanical handling components.
This standard applies to conveyors using rubber or plastic belting , with textile reinforcement (complying with BS490-1), carrying loose bulk materials, having a maximum speed of 5m/s.
This standard does not apply to the following categories but can be used as a guidance document for them:-
(a) underground mining conveyors
(b) conveyors handling materials that do not behave as bulk solids,
(c) conveyors fitted with steel cord belting.
It is proposed that the new standard will draw together the information previously contained within BS 2890 and BS 5934 with further information added with regard to basic conveyor and component selection, grades of idlers, typical values for basic calculation purposes and typical conveyor calculation examples.
If you have any comments regarding the existing contents of the above standards or views about the inclusions within the proposed standard then please contact me.
