1. The material capacity gradually decreases. During the operation of the equipment, the wheat will go through multiple processes. As the endosperm is gradually scraped off, the bulk density of the material will be reduced. The smaller the capacity, the faster the rate of reduction will be, resulting in a decrease in unit flow.
2. Uneven wheat grains. Under the same grinding system, when the particle size of the material particles is very different, some smaller particles are difficult to be ground, so that the function of the equipment cannot be played well, and the output will be reduced.
3. During operation, as the rolling distance decreases, the length of the grinding area will increase. At this time, the degree of pulverization increases, but the unit flow rate decreases accordingly.
4. The height of grinding teeth decreases gradually. With the continuous extension of the use time, the grinding teeth of the flour machine gradually wear out, and the moving speed of the material in the grinding area will be reduced. And because the height of the grinding teeth is reduced, the material in the gap between the two grinding teeth is reduced, and the output of the stone milling machine is gradually reduced.
