Magnetisk separering av malmpebbles i KA3 - mekaniska konceptförslag
Magnetic separation of ore in KA3 - conceptual design propositions
This has been a thesis work for an bachelor degree at Umeå university. The work has been done at LKAB?s facilities in Kiruna and its main purpose has been to investigate and construct some conceptual designs for replacing a screen with magnetic separation in KA3 concentrator plant. First all information available about magnetic separation was gathered and studies of magnetic separation at the sorting plant and studies of the plant KA3 was conducted. Companies that manufacture magnetic separators were contacted. All information gathered has led to a decision to focus the project into dry separation because it?s the most suitable type of separation. After the information gathering phase in the project the conditions for a magnetic separator was evaluated and some measurements were taken in KA3 to make sure all the measurements for a CAD model was available. Drawings from Metso were collected to. Then the conceptual designs was drawn in CAD and evaluated with personnel from process and maintenance department. The evaluation made it possible to arrange the concepts in order of possible function which is the result from this project. It has been done in the result and conclusion part of this report. Some general thoughts about the concepts were collected and added to the report as well. The results from the project is that two of the drawn concepts are good depending on who you talk to. One concept is better then the other because its more functional and it is easier to install and it doesn?t require any new construction.
