There is friction between the steel ball and the cylinder of the energy-saving cone ball mill. When the cylinder rotates, the steel ball is brought up and raised to a certain height. Due to the gravity of the steel ball itself, it finally falls along a certain track. The steel ball in the area is subjected to two kinds of forces: one is the force applied to the steel ball from the tangential direction when the cylinder rotates; the other is the force opposite to the diameter of the steel ball and opposite to the above force. The force is caused by the downward sliding of the steel ball itself due to its own weight. Therefore, the above two forces will constitute a pair of couples for any one steel ball. And since the steel ball is squeezed between the cylinder and the adjacent steel ball, the force couple will cause the steel balls to have frictional resistances of different sizes from each other, so the steel balls of each layer will revolve with the axis of the cylinder. Of course, the ball of each layer does not have a synchronous speed with the cylinder, and the revolution speed of each layer of steel balls is also different. In the area, the steel ball is thrown down from the top and bottom, so that the ore in the cylinder body has a strong impact crushing effect in the area. Due to the impact of the falling of the steel ball, the steel ball produces extremely strong and disorderly movements in the area. These include: (1) strong rolling of the steel ball above the dotted line; (2) rapid movement of the steel ball along the dotted line; (3) rapid movement of the steel ball below the dotted line with the mill barrel; (4) layers The mutual impact between the steel balls. It can be seen that the area is the place with the strongest grinding action. Most of the coarse ore particles are ground here. It can be seen from the above that the ore is mainly crushed by the impact force, the grinding and peeling force and the pressing force in the energy-saving cone ball mill cylinder.

Energy saving cone ball mill grinding
The energy-saving cone ball mill grinding operation is carried out in the mill body, and the cylinder body is provided with grinding medium. After the grinding medium is brought to a certain height with the rotation of the cylinder, it falls due to the weight of the medium. The ore contained in the cylinder is subjected to the impact of the medium; on the other hand, due to the revolving and rotation of the grinding medium in the cylinder along the axis of the cylinder, the grinding medium and the contact area with the cylinder are again produced. The ore is squeezed and ground to break the ore.
