The influence of idler durability on the number of their annual replacement has been discussed. The lignite open cast mines has been discussed more detail due to possessing data about the number of annual idler replacements as well as the scale of their recondition. The value of this market has been estimated assuming that average idler durability is about 4 year and the cost of new idler is about 200 PLN. 5HFHQ]HQW GU KDE LQ* /HFK *ádg\vlhzlf] SURI 3ROLWHFKQLNL :URFáDZVNLHM
