There are a lot of customers to inquire, ask our company to provide a bus worker axle repair service. Because many ball mills they purchased have the case where the shaft fracture occurs. Such a situation will have a certain difficulty after repair, because the ball mill that has already started is installed, once it is needed, it is necessary to handle the lining.
Therefore, it will bring great losses to customers. Then we can avoid the case of the shaft head fracture when the ball mill is produced. The answer is of course affirmation, then how to prevent the breakage of the shaft head?
Prevent the spherical macrofi head fracture mainly 2 Type:
First, it is the intensity of the shaft head. Increasing the intensity of the axis, this is undoubtedly a relatively simple and straightforward approach, and the relatively fine shaft head is directly converted into a coarse axis head, then forging treatment, to increase the strength and toughness of the shaft head. The enhanced axis has a large increase in toughness and strength, and the case where the shaft head is broken can be avoided.
Second, another way is to make a reinforcement. Increase the number of reinforced teles and welding areas around the shaft head, used to share local strength of the shaft head. The large amounts of force are dispersed into the various places of the shaft head, so that after being dispersed, the load weight of the shaft head can be smaller, so that the method of fracture is broken.In general, the strength of the shaft head is nothing more than improving the quality in the selection, and another aspect is to increase welding skills and workers in welding, although it will increase costs to some extent, but the effect is indeed compared It is effective, so the real material is the foundation of quality.
ball mills are typically made of cast iron. Cooling water is required interior of the surface of the tile surface. The ball mill is equipped with a tile lining and the outer ring is spherical. Typically, it is not easy to cause breakage when power is uniform. ball mills in some particularly harsh environments, such as stop water during the northern part of the winter, low temperatures to freeze the cooling water inside the surface of the tile surface, and spherical tiles break under the role of expansion. Fast recovery production is to handle today.
1. Clean up work. First clean the broken part of the new ball mill, to remove the flush of cracks and nearby regions.
2. Welding preparation. Stitching spherical tiles. If the spherical tile is not broken, find the starting point and end point of the crack, then shovel the V-shaped slot at the crack and clean it.
3. Welding. First, the temperature of the spherical brick is heated to about 300 degrees with a charcoal baked spherical brick, and then welded by air welding with a balloon cast iron electrode. Welding requirements is that the welding surface should be flat. After the spherical tile is cooled, the welding surface needs to be grounded.
4. Install after welding. During the installation process, it is necessary to observe whether the spherical tile varies. If deformed, the ball mill spherical watts must be used once until the spherical contact reaches 75%.Follow this procedure so that everyone can quickly resolve problems in production sphere tile mill broken, so that everyone can resume production quickly.
The ball mill has the loss of these energy. First, the energy loss is generated from the mechanical energy output from the ball mill motor to the mechanical energy of the abrasive medium, depending on the transmission efficiency. Then there is a little, the loss of energy is that the motor generates a rated loss when the motor is converted into mechanical energy, depending on the efficiency of the motor. Lost, the energy loss is that the mechanical energy of the ball mill is changed to the surface of the ore. After the first two losses, a part is used as a useful work, and the other part becomes a ball mill broken.
