Ball press machine is a professional equipment for pressing all kinds of mineral powder into balls, so how to judge the quality of finished products of ball press machine in production? There are the following methods:

1. Immersion strength is an important point to consider. Randomly take several pressure balls and immerse them in clean water at 25 degrees Celsius. After 2 hours, take them out and measure their strength, and take the average value in N/ ball.

2. Thermal strength is the strength of the material. Randomly take several balls, bury them in an iron box filled with clean fine sand, and take them out immediately after keeping the temperature at 850 degrees Celsius for 30 minutes to determine their compressive strength, and calculate the average value, with the unit of N/ ball.

3. Cold strength: Randomly take several pressure balls and put them flat on the intelligent shear strength testing machine one by one for pressure feedback test, record the indicated pressure value of each ball when it cracks, and then calculate the average value in N/ ball. If the error between the strength value and the average value of each ball is within the range of +50N, the experimental environment temperature is 25 degrees Celsius.

4. Because the industrial analysis, calorific value, chemical activity, slagging characteristics and ash fusibility of ball are determined according to the relevant national standards.

The above are the main methods to judge the quality of the finished product of the ball press machine, and it is necessary to master the above methods. Our company produces and sells biomass briquetting machine, ball press machine and carbonizing furnace. If you need it, please contact us.
