Ball press machine, is a device that uses high pressure to compress and shape various powdery materials into solid balls. It is widely used in industries such as metallurgy, chemical engineering, coal, and refractory material. However, one common problem that users may encounter is ball sticking, which refers to the phenomenon that the balls produced by the machine stick to the rollers or the mold and cannot be discharged smoothly. This not only reduces the efficiency of production but also damages the equipment and wastes the raw materials. In this article, we will discuss some possible causes of ball sticking in ball press machine and how to solve them.

1. Excessive moisture content of the raw materials

Moisture is a crucial factor that affects the quality and performance of balls. If the raw materials contain too much water, they will not be able to form a compact structure and will easily adhere to the machine parts. Therefore, it is recommended to dry the materials before feeding them into the ball press machine. The optimal moisture content varies depending on the type and size of the materials, but generally, it should be less than 10%.

2. Insufficient pressure or speed of the machine

The ball press machine works by applying high pressure to the materials through the rollers or hydraulic system. If the pressure or speed is not strong enough, the balls may not be fully formed or may stick to the rollers or mold due to insufficient force. To avoid this problem, you can adjust the pressure and speed according to the specific material properties and production requirements. It is also important to maintain the machine regularly and replace the worn-out parts in time.

3. Inappropriate binder or additive

Some materials may require a binder or additive to enhance their bonding strength and improve the quality of the ball. However, if the binder or additive is not compatible with the materials or is used in excessive amounts, it may cause ball sticking or other issues. Therefore, it is necessary to choose a suitable binder or additive based on the material characteristics and conduct a trial test before mass production.

4. Blockage or clogging of the discharge chute

The discharge chute is the channel that connects the mold and the ball conveyor. If it is blocked by foreign objects or excessive residues, the balls cannot be smoothly discharged and may stick to the mold or rollers. To prevent this problem, you should clean the discharge chute regularly and remove any obstacles that may hinder the flow of balls.

In conclusion, ball sticking in ball press machine can be caused by various factors, such as excessive moisture content, insufficient pressure or speed, inappropriate binder or additive, and blockage of discharge chute. To solve this problem, you need to identify the root cause and take corresponding measures, such as adjusting the machine parameters, changing the raw materials or additives, cleaning the machine parts, etc. By doing so, you can ensure a stable and efficient production process and obtain high-quality balls with minimal waste and cost.
