Energy-efficient asphalt mixing equipment manufacturers point out that asphalt mixers generate substantial heat during operation to dry and heat the raw materials. For various reasons, asphalt mixing plants often fail to operate under optimal conditions, leading to significant energy waste. Stone itself may contain a certain amount of moisture; during mixing, this moisture must first be evaporated, which consumes considerable energy. Generally, for every one-percentage-point increase in the moisture content of the aggregate, the energy consumption of the asphalt mixer rises by approximately 12%. Therefore, controlling the moisture content of the raw materials is crucial. In addition, factors such as fuel quality and fuel atomization also directly affect the mixer’s energy consumption.
Energy-saving asphalt mixing equipment manufacturers point out that asphalt mixers require heating and drying of raw materials, a process that consumes substantial amounts of fuel. Stone aggregates, particularly fine aggregates in the 0–0.27 mm size range, inherently contain significant moisture and exhibit strong water absorption. When the moisture content of stone is excessively high, it leads to considerable resource waste. According to statistics, for every one-percentage-point increase in the moisture content of stone aggregates, the energy consumption of an asphalt mixer rises by approximately 12%. Therefore, to achieve effective energy conservation, operators should carefully control the moisture content of raw materials by optimizing material quality and improving site conditions to reduce moisture levels. Specifically, quality inspections of incoming materials should be intensified, with strict rejection of non-compliant raw materials to ensure uninterrupted downstream production. In addition, environmental considerations call for the installation of storage sheds, infiltration trenches, drainage ditches, and other drainage facilities to enhance site drainage capacity, thereby minimizing material moisture content, boosting mixer efficiency, and reducing fuel consumption.
Energy-efficient asphalt mixing equipment manufacturers believe that the diameter of the aggregate also affects the operational efficiency of asphalt mixers. If the aggregate particle size is too large, mixing efficiency will decline. When the pass rate for aggregate aperture meets or exceeds 80%, mixer operating efficiency decreases by 20%; however, if the pass rate falls below 60%, mixer efficiency drops by more than 55%, resulting in substantial energy waste. Moreover, excessive deviation in aggregate aperture can lead to raw material spillage, causing even greater losses. Therefore, precise control of aggregate aperture is crucial.
Energy-efficient asphalt mixing equipment manufacturers recommend that, to enhance the mixing efficiency of asphalt mixers, batching plants should select the appropriate fuel. Currently, the most common fuels are liquid and gaseous fuels, with solid fuels used in only a small number of mixers. In terms of combustion efficiency, gaseous fuels offer higher efficiency, greater calorific value, and more stable combustion; however, their cost is higher than that of liquid fuels, making them more suitable for small and medium-sized batching plants. Although solid fuels have a relatively high calorific value, they exhibit poor combustion stability, are prone to accidents, and pose challenges for temperature control in mixers; therefore, solid fuels are generally not used as the primary fuel for mixers. Liquid fuels, by contrast, boast high calorific value, low impurity content, excellent controllability, and significantly lower costs than gaseous and solid fuels, making them highly suitable for asphalt batching plants. The two most commonly used liquid fuels in asphalt batching plants are diesel and heavy oil. Diesel is more expensive, while heavy oil is less costly and has a higher calorific value, both of which can meet the requirements of the mixer. Batching plants may use heavy oil as the primary fuel to improve operational efficiency and reduce mixer operating costs.
