Double-inlet double-outlet coal mill powdering control system

The invention discloses a double-inlet double-outlet coal mill powdering control system and belongs to the technical field of powdering control systems. The double-inlet double-outlet coal mill powdering control system comprises a material level control system, a capacity air control system, a bypass air control system and a mill outlet temperature and inlet air pressure control system. The material level control system is used for controlling the material level in a coal mill, and the capacity air control system achieves adjusting of capacity air entering the two sides of the coal mill through adjusting of the opening degrees of two capacity air doors; the bypass air control system is used for ensuring the minimum ventilation quantity and serving as a raw coal drying medium in the warm milling process and at a low output stage; and the mill outlet temperature and inlet air pressure control system adopts the cold air door as a master variable for controlling the coal mill outlet air temperature and adopts the
