本文将Bagnold剪切理论与Марков过程理论结合起来,研究溜槽类重选设备的分选机理,根据矿粒的理论转移概率,建立了分选指标与给矿参数间的定量关系,并进一步利用细粒人工混合矿在摇动溜槽上的分选结果,验证了所得的数学模型。
A mathematical model of flow-film type's gravity concentrators is be-ing developed based on the transfer probabilities of mineral particles, which are de-termined from the combination of the Bagnold's shearing theory with the principlesof Mapков processes. This model can be used to predict the grade, recovery andothers of the concentrate in terms of the feed and operating conditions.
