一、前言邦得可磨性试验愈来愈广泛地用于选矿厂设计中选择球磨机和棒磨机。对于球磨邦得可磨度,有助于选厂监测控制矿石可磨度的经常变化。邦得可磨性试验要使磨矿合格产品量达到稳定,并使其循环负荷稳定在250%左右,计算最后连续三次近似试验的每转新生成合格产品量的算术平均值。此值G即可磨度。按下式计算功指数W_i。对球磨 First, the forefront of state grindability test more and more widely used in the design of ore dressing plant choose rod mill and rod mill. For grinding ball State grinding degree, to help monitor the regularity of ore dressing plant monitoring. The Bonder grindability test results in a steady amount of qualified grinding product and stabilizes the cycle load at about 250%. Calculate the arithmetic mean of new product qualifications per revolution for the last three consecutive approximations. This value of G can be sharpened. Calculate work index W_i as follows. On the ball mill
