The invention discloses a coal impurity removing system, which comprises a feeding mechanism, a conveying device, a microwave heating cavity and a collecting device, wherein the conveying device is connected with the feeding mechanism and extends in a conveying direction to penetrate through the microwave heating cavity to be connected with the collecting device; the microwave heating cavity comprises a first chamber and a second chamber; the first chamber is located at one end, close to the feeding mechanism, of the microwave heating cavity; the second chamber is located on the downstream of the first chamber in the conveying direction; and the microwave power in the first chamber is larger than that of the second chamber. With the adoption of the technical scheme, the method for heating coal raw materials by the microwave is utilized so as to effectively remove impurities of the coal raw materials, the impurity removing efficiency is high, and the impurity effect is good; and meanwhile, the coal raw materia
