摘　　要：对两种工业醇类煤沥青水浆的制备进行磨矿试验研究,结果表明甲醇煤沥青水浆的磨矿效果略好于乙醇煤沥青水浆;建立了乙醇煤沥青水浆和甲醇煤沥青水浆磨矿动力学方程式,分别为R(t)=100exp[-(-1.3564+0.43454.lnd).t(-0.42203+0.195241.lnd)]和R(t)=100exp[-(-0.02975+0.02908.d0.67972).t(-0.12083+0.13259.lnd)],据此可以求出任意磨矿时刻待磨粒级的分布率R(t)。The grinding experiment of two kinds of CPAWS was studied,the results indicated that the grinding effect of coal pitch-methanol-water slurry was slightly better than coal pitch-alcohol-water slurry;The equations for the grinding kinetics of coal pitch-alcohol-water slurry and coal pitch-methanol-water slurry had been formulated respectively as following： R（t）=100exp[-（-1.3564＋0.43454？lnd）？t（-0.42203＋0.195241？lnd）] and R（t） = 100exp [-（-0.02975＋0.02908？d0.67972）？t（-0.12083＋0.13259？lnd）],accordingly we could work out distribution rate of any size range particles to be grinded at any time of the grinding process.
