in ball mill which force is act

May 13, 2021 F1 = - F2. for the coordinate system shown with the letter X below the ball. If we sum up the forces acting on the ball, we obtain the force equation on the left: F1 + F2 = F net = 0. where F net is the net force acting on the ball. Because the net force is equal to zero, the forces in Example 1 are acting in equilibrium

    May 22, 2019 The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact and grind the material in the cylinder to grind the material
