In the process of using the ball press machine, it is sometimes difficult to demould, which not only affects the production efficiency, but also may damage the equipment or mold. In order to help you solve this problem better, this paper will analyze the common reasons for the difficulty of demoulding the ball press machine and provide corresponding solutions.

First, the reason why it is difficult to demould the ball press.

1. The viscosity of raw materials is too high. If the raw materials contain more moisture or viscous substances, the formed pellets will adhere to the inner wall of the mold, and it is difficult to demould smoothly.
2. The surface of the mold is rough. If the mold surface is not smooth enough, it is easy to increase the friction force, which will hinder the pellets from demoulding.
3. The ball pressure is too high. When the ball press is running, if the pressure is set too high, it may lead to the tight combination between the pellets and the mold, which makes it difficult to demould.
4. Insufficient lubrication. In the pressing process, if proper lubricant is not used, the friction between the mold and the raw material will increase, which will lead to the difficulty of demoulding.
5. The proportion of raw materials is unreasonable. Insufficient binder ratio or uneven formula in raw materials may also cause insufficient strength or enhanced adhesion of pellets, thus affecting the demoulding effect.

Second, the solution.

1. Adjust the moisture and proportion of raw materials. Properly control the water content of raw materials to avoid being too high or too low. At the same time, adjust the amount of binder as needed to ensure that the raw materials have good formability and demoulding performance.
2. Optimize mold design and maintenance. Clean and polish the mold regularly to ensure its smooth surface. If the die is seriously worn, it should be replaced or repaired in time to reduce friction.
3. Set the pressure reasonably. According to the characteristics of raw materials and production requirements, the pressure parameters of the ball press are adjusted to avoid the difficulty of demoulding caused by excessive pressure.
4. Use lubricants. Adding a proper amount of lubricant, such as graphite powder or vegetable oil, to the mold surface or raw materials can effectively reduce friction and improve demoulding efficiency.
5. Improve the raw material formula. For the problem of difficult demoulding, we can try to adjust the raw material formula, such as adding an appropriate amount of binder or improving the mixing uniformity, so as to improve the molding quality and demoulding performance of pellets.
   

It is a common problem to demould the ball press, but it can be effectively avoided or solved through reasonable operation and maintenance. In daily use, users should pay attention to the adjustment of raw material characteristics, equipment status and operating parameters to ensure efficient operation of equipment, thus improving production efficiency and product quality.
