A Midwest power company experienced serious reclaim problems when handling fine eastern coal. The existing static hopper produced nothing more than a rathole and required continuous bulldozer attention which resulted in compaction. Bulldozer operator safety was another concern.
The Carman Solution:
A model 8GDH Drawdown Hopper was installed on a steel structure and concrete pad that replaced the static hopper. With only minor modifications, the existing gate and belt feeder were reused. When handling fine coal, reclaim is equal to that predicted with little bulldozer activity.
