現有磨矿机上的給矿器型式的主要缺点是生产率不高。作者在特殊的装置中,研究分析了鼓型給矿器生产率低的原因:(1) 給矿器內盖里的矿浆呈旋轉运动,难于进入給矿器的螺旋导叶板中去,并且增加了磨損;(2) 矿浆不是卸到磨矿机里去,而是从一个螺旋导叶板倒注到另一个螺旋导叶板,形成逆流矿浆,造成給矿器的堵塞現象;(3) The main disadvantage of the feeder model on existing mills is their low productivity. In a special installation, the author studied and analyzed the reasons for the low productivity of the drum-type feeder: (1) the slurry in the inner cover of the mine was rotated and it was difficult to get into the spiral guide vane of the miners, and the increase (2) The slurry is not discharged to the mill, but is poured from one spiral guide vane to another spiral guide vane to form a countercurrent slurry, which causes blockage of the mine; (3)
