Asphalt Mixing Plant Mixer Capacity Expansion and Upgrade in 4 Days: Efficiently Empowering Road Construction
In the late spring of April, road construction projects across China are proceeding at full speed. As these projects strive to enhance efficiency, asphalt mixing plants, as the key equipment for asphalt mixture production, are facing critical bottlenecks such as insufficient production capacity, uneven mixing, and high costs, which significantly hinder project progress.
Established in 2001, Hubei Changjiang Road & Bridge Co., Ltd. (hereinafter referred to as Changjiang Road & Bridge), specializes in high-grade highway construction. The company has participated in key national and provincial projects such as the South-to-North Water Diversion, the Yangtze River Three Gorges Dam Bypass, the Third Wuhan Yangtze River Bridge, and the Jingzhu Expressway. As a major force in Hubei's road engineering sector, Changjiang Road & Bridge owns multiple D&G Machinery asphalt mixing plants, including the 4000 and 5000 models. Among them, a DG4000 "Steel Warrior," manufactured in 2013, has been fighting on the front lines of road construction for 12 years, producing over 3 million tons of asphalt mixture by the end of 2025. To meet high-intensity production demands of over 500,000 tons of asphalt mixture in 2026, shorten construction periods, and ensure quality and quantity, Changjiang Road & Bridge, based on their deep understanding of D&G Machinery's product stability and service responsiveness, decisively chose D&G Machinery's mixer expansion and upgrade solution. This approach leverages a small investment to unlock massive capacity, addressing production challenges in a one-stop manner!
Precise Upgrade, Breaking Capacity Bottlenecks
The mixer enlargement project was fully tailored to the customer's schedule, production conditions, and actual capacity requirements. It adopted a solution involving the complete replacement of the expanded weighing and mixing layers. With a modular installation approach, the installation and commissioning were completed in just 4 days. At present the upgraded mixer boasts an hourly output of 320-340 tons, increasing the single-batch mixing volume of the asphalt mixture without extending the core mixing time, therefore largely lifting the equipment's output.
Less Cost, Higher Efficiency
Compared to purchasing a brand-new asphalt mixing plant, the mixer enlargement requires lower investment and offers a shorter return-on-investment period, making it a cost-effective choice for companies to optimize equipment and strengthen market competitiveness. Additionally, the expanded mixer enables a higher RAP addition ratio, ensuring the thorough mixing of recycled and virgin aggregates. This approach not only meets green construction requirements without compromising overall production efficiency, but also synchronizes capacity growth with environmental benefits.
Professional and Dedicated, Empower Success
As the enlarged mixer embarks on a new journey, this "Steel Warrior" is ready to write new chapters in upcoming road construction projects. D&G Machinery will continue to provide clients with innovative, reliable, and eco-friendly plant retrofitting solutions with its strong expertise and high-quality services, empowering green road construction!
