我矿对MQG1200×1200球磨机进行了两项技术改革,取得了良好效果。 (一)球磨机给矿方式的改革在运转中联合给矿器有一偏心负荷,电流波动大,能耗增加,动球荷不均匀,同时返砂勺头极易磨损,影响运转率和磨矿效率,有必要改革。我矿MQG1200×1200与FLG500的机组配置,原来分级机坡度为14°,排矿流槽坡度17％,返砂流槽坡度40％。前年九月,我矿重新调整了分级机的配置,使球磨机和分级机中心线尽量靠近,分级机坡度为19°,球磨机排矿流槽坡度10％,返砂流槽坡度25％,从而取消了联合给矿器,实现了球磨机自流直接给矿。
I mine on the MQG1200 × 1200 ball mill two technical reforms, and achieved good results. (A) the reform of the way to mill to the mine In operation, there is a eccentric load to the mine, the current fluctuations, increased energy consumption, uneven load ball, while back to the sand head can easily wear and tear, affecting the operation rate and grinding efficiency It is necessary to reform. I mine MQG1200 × 1200 and FLG500 unit configuration, the original grading machine gradient of 14 °, drainage runoff slope of 17%, sand flow tank slope of 40%. Last year in September last year, I mine to re-adjust the classification machine configuration, the ball mill and grading machine centerline as close as possible, classifier gradient of 19 °, ball mill drainage runoff slope of 10%, return flow gutter slope of 25%, thus eliminating the Joint to the mine, to achieve a ball mill gravity to the mine directly.
