Both modified bitumen equipment and traditional emulsified bitumen processes rely on mills, and have gradually been widely used. However, the problems that occur when using modified bitumen equipment require special attention. Only in this way can we avoid problems as much as possible and improve production efficiency:

The unreasonable process route of modified bitumen equipment causes large mill losses, and the quality of modified bitumen products is unstable. 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 force increases, huge friction heat is generated, and the temperature of the mixture rises, which easily causes some bitumen aging. There is also a small part that has not been sufficiently ground and is directly rushed out of the grinding tank, which has a direct impact on the fineness, quality, and flow of the modified bitumen, greatly shortening the life of the mill.
Because the modified bitumen equipment did not handle the SBS block problem before grinding, there was not enough pretreatment and the structure of the mill was unreasonable, and a certain fineness could not be achieved during the grinding process, resulting in low production efficiency and unstable product quality of modified bitumen products. 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 causes unstable product quality and affects the speed of highway construction.
These are the main problems that occur when using modified bitumen equipment. Everyone must operate in detail according to the instructions to effectively improve our work efficiency. If you have any questions during operation, please feel free to consult us in time.
