中文摘要：

对影响分选效果的因子进行分类处理,采用"均匀试验+正交试验"相结合的试验方案,结合提出的绝对离析值(Wash)、相对离析值(R)2个分选效果量化指标,在实验室振动流化床分选系统(D120 mm×H350 mm)上,对不同性质-6+1 mm细粒永城烟煤的分选效果波动性进行试验。结果表明,针对不同性质的入料,4种操作类因子均存在相对窄的最佳取值范围,且影响显著性依次为床层高度H>流化气速v>振动频率f>振幅A;对于2种性质类因子,与密度组成相比粒度组成变化时分选效果波动较大,试验范围内密度组成变化时R值的波动区间为70.57%~77.59%,粒度组成变化时R值的波动区间为64.59%~76.61%。
