确定磨矿机有用功率的总括公式在一些文献中〔2、3〕发表了一系列理论公式和经验公式,用以确定在某种速度规范下,耗于磨矿机筒体的所谓有用功率N_n。然而,正如在专著〔2〕中就曾首次指出,而后又在论文〔4〕中利用量纲理论予以论证那样,所有这些公式都可以看做是一些局部场合的或所谓总括公式的变形。按总括公式,有用功率(N_n)可以用两个因数的乘积方式表示:
The general formula for determining the useful power of the miner In some literatures [2,3], a series of theoretical formulas and empirical formulas were published to determine the so-called useful power consumed by the miner’s barrel under a certain speed specification . However, as was pointed out for the first time in monograph [2] and later in argument [4] using dimensional theory, all of these formulas can be considered as variants of some local or so-called omnibus formulas. According to the general formula, the useful power (N_n) can be expressed as a product of two factors:
