氧化锌矿磨矿球径经验公式研究
Study on ball size empirical formula of grinding zinc oxide ore
摘要
Abstract
According to the researches of grinding dynamics,compressive strength of natural ore and power consumption of milling,the empirical formula model of the grinding of zinc oxide ore was derived and established.The material of zinc oxide ore with the types of sandstone and the characteristics of large slime content was from Lanping in Yunnan province,China.The grinding results of mixed material showed that the model could guide the initial ball-load of ball mill accurately.After the adjustment of mill ball size distribution using this empirical equation for Yunnan Xiaohuishan zinc oxide ore processing plant,the mass fraction of secondary slime decreased by 2.30％ and grinding efficiency increased by 4.30％.The purpose of reducing the secondary slime and energy consumption of grinding was achieved.关键词
