During the preparation of flour, the flour formed by grinding will be mixed with wheat bran. In addition, when the finished flour is used for instant noodle processing, biscuit processing, and noodle processing, the flour will be mixed with large particles of impurities such as certification and packaging thread that accidentally fall into the flour. Usually the content of impurities is about 5%, in order to quickly remove these impurities , Usually choose the straight row sieve as the flour sieve, at this time the general sieve mesh requirement is 18 mesh.
The direct-discharge vibrating screen uses the exciting force provided by the vibrating motors installed on both sides of the sieve to drive the flour to move up and down on the sieve surface, and adopts a direct discharge method, and the sieved flour directly passes through the screen below. The discharge port is discharged, which is in line with the requirements of rough removal of impurities and high output of flour.
