| 摘 要： | 本文用Bagnold剪切理论,结合作者导出的矿粒在摇动溜槽中的运动速度公式,分析了矿粒在摇动溜槽中的分层和分选过程,提出了如何根据给矿性质确定最佳摇动强度的理论模式,找出了析离分层与摇动参数的关系。并进一步利用作简谐运动的实验室摇动溜槽进行细粒人工混合矿的分选试验,以验证理论分析所得的结果;试验结果与理论分析相符。

| Abstract: | According to the velocity equation of mineral particles given by the authors, the stratification and separation processes of mineral particles in the shaking sluice have been analysed with Bagnold's shearing theory. A theoretical model which determines the optimum intensity of shaking according to the feed properties is proposed and the relationship between the segregation phenomena and parameters of shaking is found. On this basis a separation test is carried out on fine artificial ore samples in a laboratory shaking sluice with simple harmonic motion in order to verify the results of the theoretical analysis. The test results are in agreement with the theoretical analysis. |
