June 2012: World Coal
Written By: Aaron Gibbs and Phil Wowak

This coal fired power plant burning PRB coal had a serious dusting problem at a primary underground transfer point. The 72” conveyors were handling a varying load from 0 to 3600 ton per hour at 650 feet per minute. The existing chute design caused extensive dusting, internal liner wear as well as material spillage and receiving conveyor belt mis-tracking due to off center loading with varying loads as well as belt cover wear.
