What are the common problems of modified asphalt equipment shared by manufacturers?
Due to the unreasonable process route, the modified asphalt equipment causes large mill losses and unstable quality of modified asphalt products. Because the SBS after swelling and stirring often forms certain blocks or larger particles, the grinding time is extremely short due to limited space when entering the grinding chamber, which causes the mill to generate a large internal pressure, instantaneous friction increases, generates huge friction heat, and the temperature of the mixture rises, which easily causes some asphalt aging. There is also a small part that has not been sufficiently ground and is directly flushed out of the grinding tank, which has a direct impact on the fineness, quality, and flow of the modified asphalt, greatly shortening the life of the mill.
Because the modified asphalt equipment did not handle the SBS block problem before grinding, there was not enough pretreatment and the structure of the mill was unreasonable, a certain fineness could not be achieved during the grinding process, resulting in low production efficiency of modified asphalt products and unstable product quality. It is necessary to rely on repeated multiple cycles of grinding and long-term incubation to solve the problem. This not only greatly increases energy consumption and costs, but also unstable product quality, affecting the speed of highway engineering construction.
