摘要
以平顶山庚组高硫煤粉为煤样,利用实验室自制的永磁强磁选机进行分选试验,发现:随着颗粒粒径的增大,其灰分、硫分也随之增加;该磁选机的最佳分选粒度范围为0.25～0.5mm;磁选脱除的主要是煤中黄铁矿硫,而硫酸盐硫和其他有机硫则变化不大。
With the high-sulfur coal powder from Pingdingshan 7th Coal Seam as the coal sample, using laboratorymade high intensity magnetic separator for sorting, found that： As the particle size increases, the ash, sulfur also increases; the optimum sorting size range is from 0.25 mm to O. 5mm; magnetic removal is mainly pyrite sulfur in coal, while the sulfate sulfur and other organic sulfur change little.
