Manganese dioxide and reduction coal mixing and crushing system

The invention provides a manganese dioxide and reduction coal mixing and crushing system. The mixing and crushing system comprises a fixed grinding head, a movable grinding head, a stirring roller, a driving device, a fluorescence detector and a control system; the fixed grinding head and the movable grinding head are combined to form a crushing cavity, and coal briquettes entering the crushing cavity are crushed and ground, so that the coal briquettes finally reach the required granularity; and the driving device drives the movable grinding head and a stirring rod to rotate. In the coal briquette crushing process, fluorescent substances are quantitatively added through a feeding pipeline, after manganese dioxide, reduction coal and fluorescent substance particles are fully mixed in the stirring section, fluorescent components in a mixture of coal powder and manganese dioxide powder are detected through the fluorescence detector, and therefore the mixing degree of the coal powder and the manganese dioxide pow
