摘　　要：为了保证被磨的矿浆液体流出筒体,防止筒体内的研磨体(钢球)随着浆液滑出,根据导流螺纹的反向旋转产生反力原理,通过在球磨机出口设计出与筒体旋转方向相反的螺纹槽,借助螺旋槽转动和钢球自身重量和离心力产生的力和力矩,有效地阻止球磨机筒体内钢球滚出,保证球磨机正常工作。In order to ensure the slurry liquid to flow out of the cylinder and prevent the grinding body(steel ball)from sliding out with the slurry,according to the principle of counter force generated by the reverse rotation of the guide thread,a screw groove is designed at the outlet of the ball mill,which is opposite to the rotation direction of the cylinder body.With the help of the force and torque generated by the rotation of the spiral groove and the weight and centrifugal force of the steel ball,the ball mill barrel can be effectively prevented The steel ball rolls out to ensure the normal operation of the ball mill.
