Bitumen supply method is relatively rough in some countries or regions, some dig a pit on the ground for containing bitumen,some others use a barrel or a large tanker, which not only does not save energy, but also cause low quality of finished mixture.Asphalt mixing plants manufactured by Liaoyuan Machinery adopt asphalt tanks, which can continuously maintain tempreture to ensure that the bitumen is in a liquid state by directly heating or heat transfer oils.The temperature is controllable,and the process is energy-saving and the finished mixture comes out with high-quality.
