NEURAL NETWORK MODELING AND OPTIMISING OF THE AGGLOMERATION PROCESS OF SULPHIDE POLYMETALLIC ORES

Abstract

During the operation of the lead-zinc production while processing of polymetallic ores, problems arose related to the qualityof products and the efficient use of equipment – agglomeration furnace and crushing apparatus. Previously, such issues were resolved due to the experiences and based on mathematical modeling of processes. The mathematical model for optimizing unnecessary such operating mode is a difficult program. Performing calculations is required a fairly large investment of time andresources. Therefore, the program of the mathematical model for optimizing the operating mode of the agglomeration furnace and the crushing device for sinter firing was replaced with a neural network byimplementing the process of training the network based on the results of calculations on a mathematicalmodel. The results obtained showed that neural network models were more accurate than mathematical models, which made it possible to solve production optimization problems of great complexity. The use ofneural networks for modeling technological processes has made it possible to increase the efficiency ofproduct quality controlsystems and automatic controlsystems for the roasting of sulfide polymetallic ores.
