In the production of ball press machine, there are always some problems and defects such as unsmooth ball surface and burrs. How to make the balls pressed by ball press machine smoother is a problem that everyone is concerned about. So how to operate to ensure the smoothness of the ball?

Here are several methods to ensure the smoothness of the ball from the ball press machine for your reference.

1.Regularly clean the ball socket of the roller.

When pressing some materials that contain more water and need to use binders, due to high temperature and high pressure, the powder of some materials will inevitably adhere to the ball socket of the roller skin of the ball press machine, which will lead to rough defects on the surface of the subsequent balls, or lead to the situation that the subsequent balls become virtual balls. Therefore, when dealing with this kind of materials, it is necessary to clean the roller skin of the ball press regularly. It is required to use tools such as brush and soft shovel to remove the residual material powder in the ball pit when the ball press stops running completely and power is cut off, but be careful not to use any corrosive cleaning agent. Clean with clean water is better.

2.Adjust the center of the ball socket. 

Sometimes there is no central comparison between the ball sockets on the two roller skins of the ball press machine, and slight dislocation will cause burrs on the balls, and in serious cases, the finished balls will be unqualified, resulting in misplaced products. At this time, it is necessary to adjust the two pairs of rollers and the bearings of the two roller skins so that the bearings are in contrast with the center points of the ball sockets of the stick. In this way, the balls pressed by the ball press machine will not have burrs, and after adjustment, there will be no deformation and slag drop during transportation. 　

3.Control the moisture content.

The moisture content of the pressed material also affects the smoothness of the output of the ball press machine. If the material is too dry, it may not be formed normally, resulting in rough surface. On the contrary, if the material is too wet, it may stick to the machine, making it difficult to take out the molded ball. Therefore, it is very important to control the water content of materials in a suitable range.

4.Adjust the pressure.

One of the most important factors affecting the output smoothness of the ball press machine is the pressure applied in the forming process. If the pressure is too low, the ball may not be formed normally, resulting in rough surface. On the other hand, if the pressure is too high, the ball will be deformed or broken. Therefore, it is very important to adjust the pressure according to the characteristics of the pressed material and the expected result.

5.Use proper lubricant.

Another factor that may affect the output smoothness of the ball is the lubricant used in the forming process. Proper lubrication can reduce the friction between the material and the machine, so it is easier to form a smooth ball. However, using too much lubricant will cause the material to become too slippery and difficult to control. Therefore, it is very important to use an appropriate amount of lubricant according to the characteristics of the pressed material.

6.Choose the right mold.

The mold used in the ball press will also affect the smoothness of the output. The surface of the mold should be smooth, without scratches or other defects that can be transferred to the molding ball. In addition, choosing a mold with proper shape and size can ensure that the ball is formed evenly and smoothly.

7.Reduce the gap between the rollers.

When the gap between the two pairs of rollers of the ball press is large, the contact area of materials between the two rollers decreases, and some materials are not pressed by the rollers, which will lead to the appearance of burrs in the balls. In order to deal with this situation, we can adjust the gap between the rollers of the ball press, and pay attention to the fact that the gap between the two rollers of the ball press machine is not too small. Too small and too tight will lead to the two rollers being locked and unable to rotate, which will also reduce the life of the rollers of the ball press machine.

In a word, to ensure the smoothness of balls produced by the ball press machine, many factors should be paid attention to, such as cleaning the ball socket of the roller regularly, adjusting the center of the ball socket, controlling the moisture content, adjusting the pressure, using appropriate lubricant, choosing the right mold and reducing the gap between the rollers. But in fact, in actual production, the factors affecting the smoothness of the ball are very complicated and should be judged according to the actual situation. As a research and development manufacturer of ball press machine, our company will check each equipment before leaving the factory, and provide corresponding adjustment technical support after the ball press machine is installed to ensure the use effect of users.
