Optimization Study and Application Analysis of Heavy Medium Shallow Channel Sorting Process
Due to the inability to separate the final raw materials in the original heavy medium shallow channel sorting process and low screening efficiency.After comparison,this paper proposes an optimization plan as follows:Changing the Bohou screen to a rotary screen for 6 mm powder removal,still using the original heavy medium shallow channel system for sorting 200-6 mm,and adding a-25 mm particle size fine particle centrifuge.After optimization,the screening efficiency is 90%,achieving the expected effect.The processing capacity of the water washing system can reach 700 t/h,with a density of 1.67 g/cm3.The concentrate contains 0.7%gangue and 0.9%sludge.In addition,the efficiency of sorting quantity is as high as 99.0%,indicating the feasibility of optimizing the sorting process.
