Pulverized coal ore burning system of rotary kiln

The utility model relates to heating of rotary kilns, and overcomes the defect in the prior art and provides a pulverized coal ore burning system of a pulverized coal heating rotary kiln as well as solves the problem that the temperature of the rotary kiln is too low due to insufficient gas. In order to solve the technical problem, the technical scheme adopted is as follows: a feeding inlet of a coal mill is communicated with an outlet of a raw coal bunker, a discharge outlet of the coal mill is communicated with a feeding inlet of a dynamic powder concentrator, a discharge outlet of the powder concentrator is communicated with a feeding inlet of an anti-explosion deduster, a first spiral feeder is arranged below a discharge outlet of the anti-explosion deduster, the discharge outlet of the anti-explosion deduster is communicated with an inlet of the first spiral feeder, a pulverized coal bunker is arranged at the outlet of the first spiral feeder, a feeding inlet of the pulverized coal bunker is communicated
