Control Strategy in Coal Beneficiation Process of Heavy Media Equipment-Example of Zhenchengdi Mine in Shanxi Province
To address the problems of low intelligence and high control difficulty in the coal separation process of heavy media equipment,optimal control of the coal separation process in heavy media equipment and jigger is proposed:separation density(basic ash content)is defined as the density of the feed fraction with half of the coal concentrate and half of the tailings,and incremental ash content(density of the basic mass of material recovered in a process with infinitely small production increase)can be used in heavy media equipment and real-time control of the jigger.The self-separation process in the jigger can be used to determine the incremental ash content of the ash content in the material separation layer by correlating the ash content with the density of the separation layer.The radiation densitometer is used for online monitoring of separation layer density and real-time monitoring of heavy media density in the jigger separator to improve the control effect of coal beneficiation production process and increase the production of fine coal.
