Proposal to Develop a Belt Cleaner Efficiency Ranking Standard
Three Graphics for Standard 575 – July 2011
PROJECT BACKGROUND: At the 2007 CEMA Engineering meeting, a member asked the accessories committee for assistance specifying belt cleaner systems. He said there are certain bids that engineering firms encounter which have performance requirements for the belt cleaners. He wanted to know if a method could be created for selecting and specifying belt cleaners for different levels of cleanliness that would be similar to the horsepower calculation found in the belt book.
In general, bid packages from engineering firms are not specific when describing belt cleaners. It would be helpful to design firms if belt cleaners were categorized or classed in some manner. The working concept is akin to the CEMA idler standard which allows the conveyor designer to be confident of equivalent minimum capacities. It would also benefit belt cleaner manufactures since it would alleviate the concern that quoting the correct duty cleaner for the application will cause the loss of the bid since an insufficient duty less expensive design was unwittingly selected by the designer. Correct duty class selection benefits everybody…Design firm, Manufacturer, and End-user.
An associated project of the Belt Conveyor Accessories Committee is an effort to develop an Efficiency Ranking Standard for Belt Cleaners. Conveyor Belt Cleaners are one of the last items used on a bulk conveyor belt where the performance is not quantified. Motors, gearboxes, belts, idlers and impact beds all have measurable performance levels and capacities, but Conveyor Belt Cleaners do not.
