Making the Call Between New and Retrofit

In the world of asphalt production where innovation meets grit, the decision between retrofitting an existing drum mixer and purchasing new equipment is pivotal. We’ve got nothing against new equipment, but if you want to enhance efficiency, productivity, and profitability – and we know you do – a retrofit is the solid choice.

Retrofit Drum Mixer Customization and Downtime Reduction “Like New”

It really doesn’t matter whether you’re replacing your whole system or just the drum. It should feel “like new” either way, which means, either way, it needs to be custom and happen quickly. Not every team knows how to do that, and many won’t invest the time it takes to get the customization right, because it’s much easier to offer standardized features and call it a day.

Our engineers collaborate closely with operators to tailor the equipment precisely to their requirements and budget constraints, ensuring optimal performance regardless of the plant’s mobility. Additionally, whether it’s a new installation or a retrofit, our solutions are designed to minimize downtime, allowing operators to resume production swiftly with minimal disruption. All of our Revolution D™ drums and retrofit drum mixer solutions meet the specific needs of each operation, whether it’s a portable plant that requires flexibility or a stationary one with specific production demands.

So why would we recommend a retrofit solution? Let’s delve into four key reasons why opting for a drum mixer retrofit with the help of CWMF’s expertise could be the optimal path for asphalt plant operators aiming to upgrade or get the operation back online quickly and keep the business churning out profits.

Cost Savings and Upgraded Technology

Retrofitting can offer substantial cost savings compared to investing in new equipment when you work with the right partner who knows how to collaborate, innovate, and optimize for your specific application.

Our team can help you sidestep the hefty capital investment required for a new drum mixer while benefiting from upgraded technology, integrating advanced features and enhancements that boost efficiency, mix quality, and environmental compliance. From improved flight designs to optimized burner efficiencies, our retrofits leverage cutting-edge mixing technology to elevate asphalt production to new levels.

Enhanced Production Efficiency and Profitability

A planned drum mixer retrofit in an asphalt plant before the equipment fails can serve as a strategic way to increase production capacity. We work with asphalt plant operators to enhance productivity through various upgrades that improve the efficiency and capability of the plant. Key contributing factors we can influence and improve include:
• Improved efficiency
• Enhanced aggregate drying
• Increased drum size or capacity
• Better handling of recycled materials
• Reduction in downtime
• Automation and control improvements
• Compliance with environmental regulations

Retrofitting a drum mixer makes the process more efficient, less prone to interruptions, and capable of handling more work.

Maximized Efficiency through a Parallel to Counter-Flow Drum Mixer Retrofit

Retrofitting a drum from a parallel-flow to a counter-flow configuration is a significant upgrade for an asphalt plant, offering enhanced thermal efficiency, reduced fuel consumption, and improved mix quality. This transformation involves modifying the drum mixer design, installing a new flighting system, relocating the burner, adjusting the exhaust system, and updating the control system.

Counter-flow drums heat aggregates more effectively, handle higher amounts of Reclaimed Asphalt Pavement (RAP) with lower emissions, and provide better control over the mixing process. Collaborating with experienced professionals, like the crew at CWMF, is essential to evaluate feasibility and manage the process efficiently, ensuring enhanced plant performance, reduced operating costs, and superior product quality.

Improved Fuel Efficiency through Drum Mixer Insulation

Retrofitting a drum often includes upgrading the insulation, which helps retain heat within the drum. Better insulation reduces the heat lost to the environment, decreasing the fuel required to maintain optimal temperatures for mixing asphalt. Modern retrofit kits may include the installation of more efficient burners. These advanced burners can achieve more complete combustion, which maximizes the energy extracted from the fuel, reducing overall consumption.

Efficient drying of aggregates is crucial for fuel efficiency in the drum mixer. Moisture in the aggregates requires significant energy to evaporate. Improved drum designs can dry aggregates more effectively, thus reducing the amount of fuel needed. Retrofits that enhance a drum’s ability to handle higher percentages of RAP can also improve fuel efficiency.

This focus on improving fuel efficiency not only lowers operational costs but also promotes sustainable practices in asphalt production. Incorporating these fuel-saving technologies and strategies into drum mixer retrofits means asphalt plant operators can achieve significant financial savings while contributing to environmental conservation efforts.

The Bottom Line on Drum Mixer Retrofit Options for Asphalt Plant Managers

Retrofitting a drum mixer in an asphalt plant can substantially increase production by enhancing various aspects of the drum’s operation. These upgrades make the process more efficient, less prone to interruptions, and capable of handling a greater volume of work without overhauling your process to accommodate a brand-new drum system.
