    Nowadays, the roller mill has become the most important piece of milling equipment in the flour mill, with the grinding roller being the main working component, which directly affects the milling effect.

    According to different surface treatment technology, the grinding roller is divided into two varieties, the ‘tooth roller’ and the ‘sandblasting roller’. The sandblasting roller shape is either a drum shape or a conical, rough surface, with its rough surface created through a high-pressure air jet on the surface of the smooth roller made from brown abrasive corundum.

    According to the different processes, the sandblasting of rollers is used in the core grinding system. In the core grinding system, sandblasting plays a grinding role on the material, and its surface topography will affect the grinding effect.
