Vertical mill and ball mill are the most commonly used grinding machine in the mining industry. They are also playing different roles in different fields. Today, we will introduce our vertical mill and ball mill briefly. Then we'll talk about what are the working principle of them.
The working principle of vertical mill is:
The material with the help of gravity and the impact of the air and fall to the center of the millstone. The grinding disc in the vertical mill is evenly distributed on the lining plate of the grinding disc at a constant speed rotation, and the inclined cone type grinding roller bites the material and crushes it. Under the action of the hydraulic system, the material is processed by the action of pressure and friction force. The grinding roller does not contact directly. Small energy loss.
The working principle of ball mill is:
Ball mill steel ball when the cylinder is rotated and brought up to a certain height, due to the gravity of the steel ball itself, and finally fall along a certain track. As the ball is squeezed in the middle of the cylinder body and the adjacent ball, so the couple will make the size of the existence of friction between the steel ball, the steel ball with the axis of the cylindrical body is revolved in the region since the next fall, in the area of the cylinder body by grinding material impact will be strong. Abrasive material is crushing. It can be said that the grinding material in the mill barrel is grinded by the grinding force, the impact force and the extrusion pressure. In the process, the steel ball and the steel ball are directly connected with the steel plate, and the kinetic energy is converted into heat energy, which consumes the most energy.
