应用于选煤的空气重介流化床分选性能的研究

简述了空气重介流态化过程,分析了适合于煤炭分选的空气重介流化床的分选性能。模型机的流化特性试验及半工业和工业性试验系统上的分选试验结果表明,空气重介流化床具有良好的分选性能,可有效地分选50～6mm的煤炭。 This paper introduces the fluidization process of air dense medium, and analyses the separation performance of air dense medium fluidized bed applied in coal preparation. The results of fluidization characteristic experiments and separation experiments in pilot system and industrial system show that the air dense medium fluidized bed has a good separation performance, and can separate efficiently the coal of size 50-6 mm
