Ball press machine is an equipment that presses the mixture of coal powder or coke powder and a certain proportion of binder into ball. The finished product rate of the ball press machine is not only related to the characteristics of the materials themselves, and also has a great relationship with the proportion of materials pressed into balls. Matters needing attention in ball press raw materials mainly include the following points.

First, select binder suitable for material characteristics.

Pressing binder is widely used to improve the cohesiveness of dispersed powder materials. Generally, the ball pressing machine can’t press the material into balls well only by the characteristics of the material itself. It is necessary to add a certain proportion of additives to the material to improve the bonding characteristics of the material and other characteristics that need to be utilized. Users not only need to choose appropriate additives according to materials and their own conditions, but also use additives in a reasonable proportion. In this way, not only can qualified material balls be pressed, but also the production cost of ball pressing by mineral powder ball pressing machine can be obviously reduced, and unnecessary waste can be reduced.

Second, control the moisture content of raw materials. 

Too high or too low moisture content of material in ball press machine will affect the quality of the finished product. When the moisture content of the material is too low, the balls are prone to crack; when the moisture content of the material is too high, the finished product pressed by the ball press is too soft to meet the hardness requirements of qualified finished products. Therefore, users can control the water content of materials by controlling the amount of water added during the mixing of materials or pre-drying the materials before pressing them into balls.

Third, ensure the cleanliness of the raw materials. 

The cleanliness of the raw materials must be ensured, which is also an important factor affecting the quality of finished products. Excessive impurities in the material can affect the original characteristics of the material, and also affect the improvement of the material characteristics by adhesives and other additives in the material. Impurities with high hardness and large granularity may even cause unnecessary damage to the ball press. If necessary, a pre-screening process can be added to remove impurities from the materials.
