chute should be symmetrical in cross-section and located central to the belt in a manner which directs the solids onto the belt in the direction of belt travel • in-line component of the solids velocity at the exit end of the chute should be matched, as far as possible, to the belt velocity. This is necessary in order to minimise the power
Reclaim feeders and feeder breakers are utilised to reclaim stockpiles and ROM material at a continuous feed rate. Trucks, front-end loaders, or dozers supply feeders with material, which then deliver the material in a consistent manner to a conveyor belt, sizer, or other process equipment.
Operation of Paddle Feeders • The Paddle Feeders feed the coal on the conveyor belt from the Track hopper at a controlled rate. The paddle blades projected in the hopper slot scoop the coal from hoppers and discharge it on the conveyor belt running below. • The following points need to be checked before taking any paddle feeder into service.
