Storage and handling of bulk materials in a system of silos and conveyors requires a set-up that can regulate the flow of material, a system used within LKAB is a type of vibratory feeder. These are heavily loaded resulting in continuous wear, shock and vibration. Problems that often arise are fatigue, extensive abrasion as well as bearing-failures and damaged fittings. The aim of this project was to develop the next generation feeder with focus on safety, availability and maintainability. A new design has been developed with respect to these goals and clear improvement opportunities have been presented. Through a needs analysis with study visits as well as examination and operation of the feeder systems, areas of improvement have been identied. A requirement specication has been developed to clarify the target values for the new solution and thus accommodate the needs. The developed solution maintains flow characteristics from existing systems and results in a weight loss of over 1200 kg as well as more efficient maintenance procedures.
