The asphalt mixing plant will produce a lot of heat in the working process to dry and heat the raw materials. Due to various reasons, asphalt mixing plant is often not in the best working state in the working process, which will cause a lot of energy waste. The stone itself may contain a certain amount of water. When the mixing plant works, it is first necessary to dry the water in the stone, which will consume a lot of energy. Generally speaking, the energy consumption of the asphalt mixing plant will increase by about 12% for each percentage point increase in the water content of the stone. Therefore, it is very important to control the moisture content of raw materials. In addition, fuel quality, fuel atomization and other factors will also directly affect the energy consumption of the mixing plant.
