Bucket wheel excavators operating under difficult mining

Oct 22, 2021 · The aim of the project was to develop solutions to reduce failure rates of bucket wheel excavators working in such conditions. This could be achieved either by reducing the sensitivity of excavators on pulse load or by efforts to reduce the size of dynamic loads. Research in the BEWEXMIN project included three work packages.

PERFORMANCE AND ANALYSIS OF BUCKET WHEEL …

Bucket wheel excavators are the ideal solution: they can move as much lignite and overburden in a day as 40,000 workers-240,000 cubic meters, equivalent to more than 10,000 dump truck loads. The material is picked up by the bucket wheel and transported on conveyors over three meters in width. The overburden is dumped by spreaders. 2.
