摘 要:本文在总结和分析前人提出的粉碎功耗理论的基础上,从粉碎过程的动力学出发,建立了一个新的能耗公式,称之为能耗-产率方程式: E=A∑i=1N(1/(xi+1n-1)-1/(xin-1))[Ri(o)-Ri(t)] 并用四种矿石(石英、方解石、铜矿石和铁矿石)的试验结果,验证了新建立的方程式,其结果是令人满意的。
Abstract: On the basis of summarizing and analysing the laws of comminution proposed, a new equation of comminution work, known as the energy-yield equation, is established in terms of the comminution kinetics: E=A∑i=1N(1/(xi+1n-1)-1/(xin-1))[Ri(o)-Ri(t)] and the equation has been examined by the grinding experiments on four kinds of ores (i. e. quartz, limestone, copper and iron ores). The results obtained are very satisfactory.
