Why is the sieve mesh on the wheat flour mill tilted?

The processing effectiveness of the sieve mesh itself directly impacts the production quality of wheat flour mills. Consequently, both the installation method and technical parameter settings of the sieve mesh must meet production standards. However, users occasionally observe the sieve mesh tilting during operation. What causes this?

　　Generally, screen tilting in flour mills stems from an uneven screen body. Personnel must reposition shims to level the frame and make adjustments. Alternatively, it may result from inconsistent axial stiffness in the rubber springs, causing uneven compression. In such cases, personnel should replace the springs with appropriately selected ones to achieve uniform compression and level the structure.

　　Should operators detect an incorrect movement trajectory of the sieve body, attention must be paid to differing excitation forces between the two motors. Adjust the counterweight on one motor to equalise the forces. If the combined excitation force of both motors fails to pass through the sieve body's longitudinal symmetry plane, loosen the U-shaped fastening bolts and reposition the motor symmetrically relative to the other. Replace rubber springs that have failed due to deformation.

　　Analysis of the wheat flour mill's production process indicates that material deviation frequently occurs during the flour cleaning stage. Failure to address this leads to persistent deviation, disrupting material classification and reducing cleaning efficiency. Operators must therefore prioritise this issue: upon detecting anomalies, promptly halt operations to identify and resolve the cause.
