The endless infrastructural needs are the sole basis for efficient machinery to aid in the job. One of the most frequently used devices for these tasks is an asphalt mixing plant. Asphalt is a crucial road construction material, and its production is an extensive process, requiring high quality. There are various options for the plant on the market, and an assessment is essential to highlight the critical aspects. To make your work easier, here are several considerations to help you achieve this goal.

Type of Machine

There are distinct kinds of asphalt mixing plants, and although they aim to achieve a similar goal, their functioning and quality levels can differ. The options fall into two primary categories: asphalt batching plants and asphalt drum mixing plants. The batching model produces asphalt in batches, allowing for changes in the mix specifications. This flexibility makes it suitable for different paving goals. Operators can customize the screens, altering the composition while the machine is running. The second model, the drum mixing device, requires fewer components to achieve production goals. It can produce higher volumes of asphalt continuously, making it the best in its category despite varied needs.

Price

The price of asphalt mixing plants speaks volumes about their quality. Drafting a budget is crucial to avoid overspending, as your investment will require additional operational funding. Among the two classes highlighted above, there are mobile and stationary asphalt mixing plants. Mobile versions have a higher purchasing price compared to their stationary counterparts. However, if frequent movement isn't required, stationary designs may be a suitable and cost-effective choice. Reputable manufacturers, who often charge more during machine manufacturing, usually request higher prices. These manufacturers provide warranties, spare parts, and after-sales services, ensuring reliable machines that offer a seamless working experience.

Size

Production volume is another critical factor to consider. How much asphalt do your projects require at any given time? Assessing an average amount will guide you to choose an ideal machine. If you focus on small production quantities, large appliances may not be necessary, as they could result in wastage. On the other hand, using a smaller machine in a large setting could cause delays, reducing business efficiency and risking your reputation.

The above standards will help you make an informed decision as a buyer. Size, price, and machine design are key factors determining product quality. Also, ensure that you account for the expenses required to keep your business operational.

How to Choose the Right Asphalt Plant

Choosing the best asphalt plant is not easy, especially if you are new to the industry. There are numerous parameters to consider. The goal is to select a machine that meets your needs and helps complete your projects without issues. The best way to do this is to select equipment based on market demand.

Purchasing this equipment is critical for your business and differs from other road-building equipment. It's a capital investment that will last many years, as an asphalt plant cannot be easily discarded. A hasty purchase decision can prove fatal. Different companies will have varying views, which can create confusion. If the decision goes wrong, there's no going back.

It's not just about low production, breakdowns, or poor quality. Poor mix can lead to long-term road damage, causing significant losses. Therefore, understanding your requirements and budget is crucial before approaching asphalt mixing plant manufacturers.

Long Term Planning

Long-term planning is essential as this equipment will be used for various future projects. If you have a small project, consider settling for a mid-size plant. This allows you to confidently take on bigger projects later without investing in another higher-capacity machine. Understanding your competition is also important. A slightly more expensive machine that promises low production costs can be beneficial in the long run. Ensure you have a skilled operator and acquire some basic knowledge before meeting manufacturers. Get reviews on current equipment and trends. Also, check which manufacturer offers better service and reasonable spare parts costs.

Types of Asphalt Plants

There are two basic types of asphalt plants available: batch type and drum type.

Batch Plant

Asphalt batching plants produce hot mix asphalt in batches. The process involves cold aggregate feeder bins, drying drums, and vibrating screens that separate and store aggregates in compartments based on size. The aggregates, bitumen, and filler material are weighed and mixed in a twin shaft batch mixer. After mixing, the materials fall into waiting trucks or storage silos.

Batch plants can make reasonable hot mix asphalt from any material and allow changes in mix specifications during operations. The screens can be customized and replaced easily. However, batch plants may require additional time for weighing and mixing, which can impact productivity.

Bottom Line

If you do not need to change mix specifications often and require high production rates, a batch plant may not be the best choice.

Drum Plants

Drum plants, also known as drum mixers, are continuous-type plants that produce hot mix asphalt in a simpler process. Cold aggregate feeders transfer aggregates to the drum, where they are weighed and mixed with bitumen and filler material. This process is continuous, making drum plants ideal for high production volumes.

Drum plants require fewer components, making them easy to own and maintain. They are suitable for high production in limited space.

Bottom Line

If you frequently change mix designs or require high precision, a drum plant may not be the best option. Drum plants are easy to operate and maintain, with lower costs compared to batch mixers.

Counterflow Asphalt Mixing Plant

This continuous plant has separate zones for drying and mixing. Aggregates are treated to a flame for moisture removal in the first chamber and then passed to the mixing zone before being transferred to storage silos or waiting trucks.

Bottom Line

The counterflow design is more efficient than drum mix plants. It is a mid-point option between traditional drum mix plants and batching plants.

Styles of Asphalt Plants

There are two basic styles of hot mix plants: stationary or mobile asphalt plants. Mobile plants are more expensive but are ideal if frequent movement is required. Stationary models are cost-effective for long-term projects at a single location. When choosing a mobile plant, it is essential to consider transportation and the need for mobile accessories. Mobile mixers take less time to assemble and disassemble, making them suitable for short-term projects.

Size of Asphalt Mixing Plants

The size of the equipment depends on the production requirements. Calculate the required capacity in tons per hour based on your project needs. Choose a slightly larger machine to account for potential interruptions. Consult with asphalt plant manufacturers to determine the right capacity based on your mix material design and operating conditions.

Plant Components and Customization

Consider the accessories and components that provide the best return on investment. Common accessories include cold feed bins, asphalt tanks, hot mix asphalt storage, pollution control devices, burner units, RAP addition, spare parts, and control panels.

Cold Feed Bins

Customizing cold feed bins is essential if you use multiple types of aggregates. Ensure the plant has enough bins to accommodate your mix design, with provisions for vibrating motors if required.

Number and Capacity of Asphalt Tanks

Calculate the required tank capacity based on your supplier's distance and the frequency of bitumen usage. Multiple or larger tanks may be necessary to avoid production breakdowns. Consider mobile storage tanks for flexibility.

Storage of Hot Mix Asphalt

Inadequate storage leads to frequent shutdowns and high per-ton costs. Invest in larger storage silos to manage production efficiently and reduce waiting times for truck arrivals.

Pollution Control Devices

Choose manufacturers offering primary and secondary pollution control units. Bag filters are efficient for capturing dust particles and gases, though more costly than wet scrubbers. In the long term, bag filters are preferred for compliance with pollution control norms.

Burner Unit

Select a simple, maintenance-free burner with economical and readily available fuel options. Consult manufacturers for fuel consumption estimates based on your mix design and operating conditions.

Addition of RAP

Reclaimed asphalt pavement (RAP) is increasingly popular. Discuss with manufacturers to ensure the plant can handle both virgin and RAP materials.

Spare Parts

Compare spare parts costs and availability between manufacturers. Ensure the control panel components are from reputable brands and easily replaceable.

Control Panel

The control panel is crucial for efficient operations. Verify its components, ease of use, and calibration processes. Ensure the panel is rust-free and uses readily available parts.

New or Used Asphalt Plants
