列宁格勒矿业学院进行了在瀑落磨矿条件下球磨机磨矿工作过程的研究。粒度6—0毫米的石英(γ=2.65克/立方厘米)在有平滑衬板的300×200毫米球磨机内进行磨矿试验。矿浆固:液此为3:1(按重量),其可变的容积占球之间空隙容积的70%;直径40毫米的球有50%,直径28毫米的球有35%,直径21毫米的球有15%。装球量的空间为球磨机容积的35%,因此在装球量占球磨机容积10%的时候矿浆容积约为球磨机容积的2.5%,在装球量30%时,矿浆容积约占球磨机容积的7.5%,在装球量50%时,矿浆容积占 The Leningrad Mining Institute conducted a study of the ball mill grinding process under waterfall conditions. Quartz with a grain size of 6-0 mm (γ = 2.65 g / cm³) was ground in a 300 × 200 mm ball mill with a smooth backing. Slurry solid: This is 3: 1 by weight, with variable volume accounting for 70% of the void volume between balls; 50% for balls 40 mm in diameter, 35% for balls 28 mm in diameter and 21 mm in diameter The ball has 15%. The volume of the ball is 35% of the volume of the ball mill, so the volume of the ball is about 2.5% of the capacity of the ball mill when the ball content is 10% of the ball mill volume. When the ball content is 30%, the volume of the slurry accounts for 7.5% of the ball mill volume %, 50% of the installed ball, pulp volume accounted for
