Not all asphalt mixing plants use pulverized coal injection; the selection of pulverized coal type requires comprehensive consideration of factors such as cost and environmental impact.
I. Fuel Types and Advantages/Disadvantages of Asphalt Mixing Plants
Asphalt mixing plants are equipment used to produce asphalt concrete, and they utilize a variety of fuels. Common fuels include fuel oil, natural gas, and pulverized coal. Taking pulverized coal as an example, it is more economical than fuel oil and natural gas, but factors such as combustibility and particle size must be considered when selecting pulverized coal.

Powdered coal is the primary fuel in modern asphalt mixtures. Previously, heavy oil was used to mix with asphalt, but heavy oil is expensive and corrosive. While natural gas is a clean energy source, its supply is limited by geographical constraints and its high fuel cost. Therefore, powdered coal has replaced it in asphalt mixing plants.

Asphalt modifiers are high-performance materials widely used in highway construction. They significantly improve the performance of asphalt mixtures, increasing road service life and safety. This article will detail the functions, types, and advantages of asphalt modifiers in practical applications.

Asphalt emulsifiers are chemical substances that mix asphalt with water, dispersing it to form an emulsion. Asphalt emulsifiers have wide applications in road construction, waterproofing projects, and coating manufacturing. This article will introduce the functions of asphalt emulsifiers from the following aspects:

In road construction, waterproofing projects, and other fields, bitumen is a core material, and its storage and transportation directly impact project efficiency. Bitumen bagged melter equipment, as a key tool connecting packaging and use, is particularly important for its performance and adaptability. However, standardized equipment on the market often fails to meet diverse engineering needs. This is where the role of custom asphalt bagged melter equipment manufacturers becomes apparent – ​​solving the matching problem between equipment and application scenarios through customized design.

I. The Role of Emulsifiers
In the construction of asphalt pavements, asphalt emulsifiers are added primarily to improve the performance of the asphalt. The addition of emulsifiers can reduce the solubility of asphalt, improve its plasticity, and enhance its shear strength, crack resistance, and durability.
