Study on the Optimization of Grinding Efficiency in Gold Mine Concentrator

Through the investigation of the mill grading process of the concentrator, the operation concentration is determined, analyze the feeding and drainage of the ball mill, feed, overflow and sand return, and understand the problems of various operations, production status of various processes and units in the mill grading process, and evaluate the reasons of 10% of + 0.6 mm content of the selected material. Through the optimization of process parameters, adjusting the amount of grinding and grading supplement, the grinding concentration and grading concentration are reasonably controlled, and the particle size composition of operation products is optimized. Through the optimization of equipment parameters, the size of hydrocyclone overflow core and sand settling nozzle are adjusted to optimize the classification effect. Through the optimization of grinding efficiency, the content of + 0.6 mm was reduced from 10% to less than 1%, and the content of − 0.074 mm increased from 45 to 50%; the recovery rate increased from 93.17 to 93.41%, increasing by 0.24%.
