在计算矿粒解离度的时候,常常假设破碎的矿粒是圆形的,并提出了一种当量直径的概念。对于短而粗的矿粒,这种假设是恰当的,但对于细而长的矿粒,用这种假设进行矿粒解离程度的计算,就会出现很大的误差。为了得到任何形状矿粒的当量直径 D_p,以便比较准确地计算矿粒的解离度,又提出了一个新的矿粒形状校正系数 Fs,该系数 When calculating the degree of mineral particle dissociation, it is often assumed that the broken mineral particles are circular and a concept of equivalent diameter is proposed. This assumption is appropriate for short and coarse ore particles, but large and long errors in the calculation of the extent of ore particle dissociation occur with this assumption. In order to obtain the equivalent diameter D_p of mineral particles of any shape, in order to calculate the dissociation degree of mineral particles more accurately, a new particle shape correction coefficient Fs
