摘　　要：探讨了微波干燥浮选精煤的原理，通过实验确定了影响微波干燥浮选精煤的主要因素：微波有效的输出功率；浮选精煤的外在水分；微波干燥的处理能力及干燥时间等。论证了以微波技术替代传统的火力干燥方法在选煤工业上应用的可行性。This paper probes into the detailed theory of microwave drying clean coal fromfloatation and determined by experiments the main factors affecting drying effects :example,thenet output power of microwave,the free moisture of clean coal from floatation,the productivityof microwave drying and the time of drying, etc.the feasibility for microwavw to replace conven-tional thermal drying in coal preparation is also demonstrated.
