Technical Field
[0001] This utility model relates to the field of screen device technology, specifically a modified asphalt screen device. Background Technology
[0002] An asphalt screening device is a device used to screen asphalt particles. It is mainly used to remove impurities and non-compliant particles from asphalt to ensure the quality and stability of the asphalt.
[0003] Common modified asphalt screen devices typically use a screen body to screen and separate particles of different sizes, with the screen body fixed by an outer frame and the entire screen device supported by a bracket.
[0004] However, when screening modified asphalt, it needs to be placed on the surface of the screen. The modified asphalt generally accumulates on the surface of the screen, resulting in uneven distribution and slow screening. Modified asphalt is made by adding admixtures such as rubber, resin, and polymers. These admixtures may affect the adhesion of the asphalt, making it more likely to adhere to the surface of objects than ordinary asphalt. Consequently, modified asphalt tends to adhere to the surface of the screen, hindering effective screening. Utility Model Content

Modified asphalt is made by adding external admixtures such as rubber, resin, and polymers, which may affect the adhesion of the asphalt, making it more easily adsorbed onto the surface of objects compared to ordinary asphalt. This leads to the modified asphalt easily adsorbing onto the surface of the screen, preventing effective screening of the modified asphalt.
