Basic Production Principles of Emulsified Asphalt Equipment

As a professional manufacturer of emulsified asphalt equipment, we have long been dedicated to the production and research and development of high-quality asphalt equipment. To help you gain a more comprehensive understanding of our emulsified asphalt equipment, our professionals will now provide a brief explanation, which we believe will be helpful in understanding the product.
In an asphalt-water system, emulsifier molecules migrate between the asphalt and water interface. The hydrophobic groups of the molecules adsorb to the asphalt surface, imparting an electric charge, while the hydrophilic groups enter the aqueous phase. This bonds the asphalt particles to the water, reducing the interfacial tension between the two. Furthermore, because the asphalt particles have the same charge, they repel each other, preventing them from agglomerating, thus enabling the asphalt emulsion to maintain uniformity and stability for a certain period of time. The nature of the charge is determined by the charge of the hydrophobic groups or hydrocarbon chains of the emulsifier. If the charge is negative, the asphalt particles have a negative charge, and the resulting emulsion is anionic. Conversely, the emulsion is cationic. If the asphalt particles have both negative and positive charges, the emulsion is zwitterionic; there are also non-ionic asphalt liquids.

    I. Overview of the Asphalt Drum Turner
    Asphalt drum turners are commonly used in asphalt production lines. Their function is to invert drums filled with asphalt to pour the asphalt for subsequent production and processing. The working principle of an asphalt drum turner is very simple; let’s take a closer look.
    II. Working Principle of an Asphalt Drum Turner
    Asphalt drum turners use a mechanical device to tilt and flip the drums containing asphalt, allowing the asphalt to flow out into storage tanks or onto conveyor belts. Specifically, the working steps are as follows:
    1. Place the drum containing asphalt on the drum turner’s workbench.
    2. Once the drum begins, the mechanical arm clamps the drum, lifts it, and then tilts it to a certain angle.
    3. The tilt angle is gradually increased. When the drum reaches a certain level, the asphalt will flow out into the storage tank or conveyor belt below.
    4. After the asphalt flows out, the robotic arm flips the barrel, releasing any remaining asphalt.
    5. After the tilting and flipping operations are complete, the robotic arm returns the barrel to its original position.
    III. Advantages of the Asphalt Drum Turner
    The asphalt drum turner utilizes advanced mechanical technology to effectively improve production efficiency and reduce labor intensity and time costs. Furthermore, its tilting and flipping operations ensure sufficient asphalt flow, avoiding waste, improving resource utilization, and reducing production costs.
    Overall, the asphalt drum turner is an indispensable piece of equipment in an asphalt production line. Its advanced technology and simple, easy-to-use operating principle provide strong support for asphalt production.

    We should select products that meet the specifications, and we should not select raw materials that do not meet the specifications.

    In recent years, with the continuous development of various industries, the production of various equipment including modified asphalt equipment has been further developed and applied. Professionals introduced that in the process of using modified asphalt equipment for production, the terminal control system implements full automatic control of medium weight, working temperature, working flow, valve opening and closing, etc., thereby ensuring the quality of modified asphalt and greatly improving production efficiency. Now Shandong Duxiu Factory will explain the operating advantages of modified asphalt equipment to customers:
    The base asphalt is heated to 150-170℃ in the rapid heating tank and then enters the blending tank to mix with the modifier fed in through the feeding device. The asphalt pump at the bottom of the blending tank then sends it to the colloid mill for high-speed grinding and shearing, so that the modifier and base asphalt are fully dissolved in extremely small particles, thereby improving the various properties of the asphalt. The finished modified asphalt after high-speed shearing and grinding enters the finished product development tank at the rear for direct use.

    We have conducted in-depth research on asphalt distributors and have accumulated a lot of production technology experience. We have conducted professional and in-depth research on some problems existing in the market to provide convenience for everyone in future production applications.
    Every time when spraying asphalt, the asphalt distributor does not spray asphalt. Troubleshooting. The asphalt distributor does not spray asphalt. It is a common fault. The following teaches you how to solve the problem of not spraying asphalt.
    1. No asphalt spraying
    Analysis of the reasons may be the following reasons:
    1. Is the asphalt pump working?
    2. Are the valves adjusted correctly?
    3. Is the pump or pipeline blocked?
    2. Troubleshooting method
    1. Check whether the hydraulic system is working properly?
    2. After adjusting the valve position, the asphalt distributor must be cleaned to avoid pipeline blockage when used next time. Because the asphalt distributor has different high and low configurations, it can spread various high-viscosity and high-temperature modified asphalts and rubber asphalt in high configuration. If you mistakenly use a low-configuration asphalt truck to spread this type of asphalt, you must spray the asphalt inside the entire vehicle clean after the first use. After spraying, in order to leave no residual asphalt, you can use waste diesel to clean it. Our company’s vehicles are equipped with air cleaning and gravity cleaning devices. Diesel cleaning is a reliable cleaning method.

    In modern highway maintenance work, how to repair asphalt pavement quickly and effectively has become one of the key issues. As an advanced repair technology, cold patching technology is very popular because of its convenient construction and remarkable effects.

    Asphalt distributors can spray, lay, and compact asphalt, improving construction efficiency and ensuring project quality.
    Asphalt distributors play a crucial role in modern road construction. They not only efficiently apply asphalt but also assist with laying and compacting, providing strong technical support for road construction. So, how do asphalt distributors accomplish these three key tasks? Let’s take a closer look.
    1. Asphalt Spraying: Uniform and Efficient, Improving Project Quality
    One of the primary functions of an asphalt distributor is to spray asphalt. It evenly applies asphalt to the road surface, ensuring the thickness and uniformity of the asphalt layer meet design requirements. During the spraying process, the asphalt distributor can adjust the spraying speed and volume according to actual needs to meet varying road conditions and construction requirements. Furthermore, asphalt distributors are equipped with advanced control systems that precisely control the amount of asphalt sprayed, avoiding waste and pollution.
    2. Asphalt Paving: Smooth and Dense Paving, Improving Road Performance
    After spraying asphalt, asphalt distributors can also perform asphalt paving. It quickly spreads the asphalt sprayed on the road surface and, through vibration or rolling, makes the asphalt layer denser and smoother. This step is crucial for improving the road’s smoothness, density, and skid resistance. The asphalt spreader’s laying process ensures that the asphalt layer is tightly bonded to the base layer, forming a complete pavement structure.
