[0002] Smooth discharging is the core of grinding equipment, which can ensure production efficiency and guarantee the owner's revenue. The conventional discharging methods on the market are static discharging and dynamic discharging, that is, axial discharging. When the viscosity of the material is high, only axial discharging can be used. However, with the continuous updating of new materials and new formulas, the viscosity of some materials is also increasing. Because the material particle size is required to be smaller on the basis of the increased viscosity of the material, the conventional axial discharging cannot meet the grinding of the material. Even if the discharging diameter is increased, the gap separator will be blocked or the feed port will be blocked due to the slow discharging of the accumulated material in the pipe, affecting the operation efficiency.
