With the continuous development of flour milling machinery manufacture industry, a series of new type flour milling machinery has shown up. Meanwhile the accessories of new type flour milling machinery have become more complicated. Once there are malfunctions, the operations will be more cumbersome. Accessories of new type flour milling machinery are largely identical but with minor differences, and they can work well. The main difference lies in the model difference and the usage of some special accessories.

The flour extraction rate of new type flour milling machinery is very stable under normal operation status. Once the extraction rate is smaller, it’s quite likely that the roller and spring have a problem and cause the gap to be bigger. We should make corresponding adjustments. Another reason may be that the sieves are blocked or damaged, we should make timely treatment.
