Adjustment and maintenance of screening equipment in the flour mill
In the cleaning process of the flour mill, the appropriate sieve holes should be selected according to the effect of the screening, and the sieve should be adjusted if necessary.
The screening test can be used to select a sieve with a larger mesh holes if the small impurities removing effect is not good. When the raw material contains high amount impurities or the moisture content is too high, in order to ensure the impurity removal effect, a larger sieve hole should be selected; when there are more small size wheat in the raw material, a small sieve hole can be selected to remove the small impurities.
During the operation, attention should be paid to the smoothness of the screen hole to ensure sufficient effective screening area. The screen should be cleaned frequently. The screen should not be deformed by heavy strength when cleaning. The working state of the rubber ball below the screen surface should be checked frequently. When the rubber ball is found to be stuck or worn, it should be repaired or replaced in time.
