The invention discloses a coal impurity removing system and a control method applied to the system. The coal impurity removing system comprises a feeding mechanism, a conveying device, a micro-wave heating cavity and a collection device; the conveying device is connected with the feeding mechanism and extends along the conveying direction to pass through the micro-wave heating cavity and be connected with the collection device; and the system further comprises a receiving device used for receiving the impurity content of coal and the target impurity content, and a control device used for obtaining the impurity removing content according to the impurity content and the target impurity content and for controlling the power that a microwave generating device applies to the micro-wave heating cavity, and/or the conveying speed of the conveying device. According to the invention, impurities of coal are removed in a manner that the coal is heated by microwave, so that not only can the effects of dehydration and des
