Whether it is a small street in the countryside, a highway in the city, or a highway, asphalt is indispensable. Although asphalt is an amorphous substance with no fixed melting point, it needs to be highly fluid when used. Therefore, the asphalt needs to be ground to reduce the phenomenon of asphalt agglomeration. Therefore, it is necessary to design an asphalt emulsification grinding machine.
