How a ball mill works  

Working principle of the ball mill | ball mill ball mill ball mill factory price  

Ball mill is mainly composed of cylindrical simple rest, zi cap, bearing and transmission ring and other parts, simple rest into the diameter of 25-150mm steel ball or steel rod, known as the grinding medium, its loading capacity for the whole simplified has a larger volume of 25%-50%.  The end cover at both ends is connected with the flange at the end of the cylinder body using screws. The middle of the end cover is perforated, which is called the hollow journal. The hollow journal is supported on the bearing and can be rotated simply.  The cylinder rest is also fixed with a large gear ring 4.  In the drive system, the motor drives the big gear ring and cylinder rest through coupling, reducer and pinion gear, slowly turning.  When the mill rotates, the grinding medium rises to a certain height with the mill, and then falls down in a parabola, as shown in the right figure in Figure 1-3.  

Materials with hollow shaft end cover, from the left of the hollow shaft neck into the cylinder, and gradually spread out to the right to move, when materials from left to right in the process of moving, rotating Jane Hugh took the ball to a certain height and falling material will break, and part of the steel ball in a state of material barrel falls into xie has grinding effect, the whole moving process and material crushing process.  

In the working principle of the ball mill in Figure 1-3, due to the rotation of the cylinder and the movement of the grinding medium, the material gradually diffuses to the right and finally flows out from the hollow journal on the right. This type of ball mill is called overflow type ball mill.  

Another ball mill in the right end (discharge end) is provided with a grid plate (see Figure 1-4), the grid plate is composed of a number of pieces of fan hole plate, the width of the hole on the fan plate is 7-20mm, generally 7-8mm is appropriate, the material can be through the hole into the space between the grid plate and the end cover, and then by lifting the plate, the material up: promotion,  Material along the lifting plate slide through the conical block facing right to the hollow journal, and then from the hollow journal out of the machine.
