The invention relates to the field of mining equipment, and specifically relates to broken stone dust automatic detection and control equipment. The broken stone dust automatic detection and control equipment comprises a pulverizer. A clapboard is arranged outside the pulverizer, thus a semi-closed space is formed, a visibility detector is arranged at each of the four corners of the semi-closed space, the visibility detectors are connected by a wire, one end of the wire is connected with an automatic control compass on which a pointer and a conductor are arranged, the automatic control compass and a tap water switch are connected through the wire, a row of tap water nozzles are arranged on the upper end of the pulverizer, and the tap water nozzles are connected with the tap water control switch. The broken stone dust automatic detection and control equipment has the beneficial effects that the design is simple, the investment cost is lower, the dust can be effectively controlled, the atmospheric pollution is decreased, and mining enterprises can pursue sustainable development.
