Background

The thermal regeneration technology of asphalt mixture is a whole set of process technology of digging or milling, crushing, screening old pavement material, drying, heating, melting and re-mixing with a certain proportion of new aggregate, new asphalt and other materials by using special equipment to form a regenerated mixture with a certain pavement performance. In order to obtain a high-quality reclaimed asphalt mixture, crushing and screening are one of the indispensable processes for the pretreatment of reclaimed materials. Due to the presence of the asphalt in the old material, the old material hardens or even agglomerates when the temperature approaches the asphalt solidification point. As a result, the diameter of the agglomerates is larger than 50mm, and the interior of the reclaimed asphalt pavement material cannot be heated to a desired temperature in the subsequent heat-drying process. The inside of the old material is still in a hardened and caked state due to the low internal temperature, so that the caked material with the size can not be broken in the flowing process after being heated. Such agglomeration makes the subsequent process not smoothly completed, and affects the gradation of the mixture, thereby seriously affecting the quality of the asphalt mixture product. Thus, the oversized RAP needs to be crushed and sieved before heating.

At present, jaw crushers and the like are commonly used for crushing oversized RAP, and the jaw crushers work on the principle of crushing by means of extrusion or knocking. The asphalt recycling mixture is formed by bonding stones with various specifications together by viscous asphalt, and extrusion or knocking has a limited effect on the viscosity of the asphalt, so that the crushing degree is low, the use efficiency of a jaw crusher is reduced, and the recycling production efficiency of waste asphalt mixtures is influenced.
