Study on Coordinated Control System of Heavy Medium Coal Separation Density and Liquid Level
Taking a coal washing plant in Ningxia as an example,the principle and production process of heavy medium coal washing are introduced in detail.Most of the control systems in coal washing plants only focus on density control while ignoring liquid level regulation.Combined with the existing conditions,a coordinated control scheme of density and liquid level under discontinuous addition is proposed.The fuzzy control algorithm is used in the control process to further improve the control accuracy and stability.The actual test finally verifies that the scheme has a high-precision control effect and can run stably,which can meet the requirements of automatic control of heavy medium coal washing,and greatly improves the automation level of the coal washing system.
