The main functions of flour mill grinding rolls
Mar 11,2025
Crushing action
The grinding rolls crush the grains between them and break them into flour. The roll surface is deliberately patterned to enhance the crushing and shearing effect.
Agitating action
The high-speed rotation of the grinding rolls generates a fluidizing effect, making the grain particles flow rapidly between the rolls, fully contacting the rolls for uniform grinding.
Conveying action
The centrifugal force and squeezing force between the grinding rolls convey the grains through the roll gap for continuous feeding.
Sifting action
By adjusting the roll gap, fine flour and coarse particles can be separated for coarse and fine grinding effects.
Heating effect
The high-speed rotation of the rolls generates heat, which can dry the flour, but overheating needs to be controlled.
Dust removal effect
The air flow generated by the high-speed rolling removes dust impurities in the flour.
Power supply effect
Some rolls have abrasive wheels on the surface to supply electricity and generate electric sparks to polish the flour.
Proper grinding roll design and use are crucial for improving flour milling efficiency and quality.
