Jul 15, 2020 A weigh belt system controls the feed rate. In most cases, coal mill feeders are smaller than raw mill or finish mill feeders with capacities of 10-100 tons per hour. The 1 issue for coal mill operators is stickiness or coal build-up on all the material handling equipment, including the mill feeder.
Drag and Reclaim Feeders consist of strands of chain with connecting cross bars designed to pull material. The design offers a low profile in the feed area, allowing it to be filled easier by bulldozers. Drag and Reclaim Feeders are used for Reclaiming coal from a stockpile using a dozer Eliminating requirements for a hopper
Chain type feeder - The chain-type feeder, Figure 10, shears coal from the bottom of the coal hopper and feeds it to the overthrowing rotor. The coal feed rate is controlled by the speed of the chain and is usually designed for operation off a line shaft drive with linkages, clutches, and pulleys to provide individual feeder control.

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.
Optimal pulverised coal feeding in three steps Perfectly matched system components are a basic requirement for optimal three-step pulverised coal feeding. This is realised in a pressure-proof mass-flow feed system using the Coriolis principle with a horizontal star feeder. 1. Pulsation-free silo extraction
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.

Feeders are devices used to control and meter the flow of materials to meet the specified flow rate of the crushing system or process system. They are the first step in designing a crushingprocess system to meet the goals required. Several types of feeders can be used in a crushingprocess system. They are selected to suit the material, feed rates and pre-sorting.
