Description

Technical Field

[0001] This utility model relates to the field of material processing technology, specifically to a discharge device for an anti-adhesion three-roll mill. Background Technology

[0002] In many industrial production fields, such as the manufacturing of coatings, inks, and electronic materials, it is often necessary to finely grind and process various materials to meet product quality requirements. The three-roll mill, as a common grinding equipment, uses the relative movement of three rollers to squeeze, grind, and disperse materials, thereby achieving the required fineness. In actual production applications, to ensure that the ground material can be discharged efficiently and smoothly, and to prevent material from adhering to equipment parts during the discharge process, affecting production efficiency and product quality, higher requirements are placed on the discharge device of the three-roll mill. A high-performance discharge device can not only improve the continuity of production but also reduce equipment cleaning costs caused by material adhesion, ensuring product consistency and stability, which is crucial to the entire production process.

[0003] Traditional three-roll mill discharge devices have many drawbacks. On the one hand, during the discharge process, materials tend to adhere to the surfaces of components such as the discharge channel and screen plate. This not only wastes materials but may also gradually slow down the discharge speed, leading to a significant decrease in production efficiency. For example, in some large-scale production scenarios with extremely high production efficiency requirements, frequent material adhesion problems force the equipment to be stopped frequently for cleaning, seriously affecting the production progress. On the other hand, traditional discharge devices lack effective screening and separation functions, making it difficult to accurately screen the ground materials and meet the strict requirements of different products for material particle size. This results in inconsistent product quality, putting the company at a disadvantage in market competition and limiting its development. To address these issues, we have proposed an anti-adhesion discharge device for three-roll mills. Utility Model Content
