time2024/05/09
- D&G Machinery has been assisting customers in resolving various problem. In order to meet the needs of clients for sustainable development, the new generation "self-cleaning" RAP dryer drum is developed by D&G Machinery. The design has been optimized, taking into account the characteristics and heating characteristics of recycled materials. The featured "self-cleaning" patented technology greatly alleviates the drum adhesion problem and ensures the system's drying efficiency. Read on for more.
D&G Machinery, since its establishment in 1999, has been committed to R&D and sustainable development. Driven by technological Innovation and the reliability of product quality, D&G Machinery is about to usher in a milestone 25-year anniversary with continued success.
In the pursuit of sustainable development of new products, D&G Machinery not only focus on innovation, but also providing customers with technical upgrading services for old plants. D&G Machinery has always adhered to the corporate core values of "Integrity, Innovation, Responsibility, and Win-win", striving to be a manufacturer of overall solutions for road construction. We will also explore the value of old plants to provide users with service solutions that “bring new life to the old plants”.
With the power of innovation, D&G Machinery has been assisting customers in resolving various problems, such as low production efficiency and high production costs. In order to meet the needs of clients for sustainable development, the new generation "self-cleaning" RAP dryer drum, first-of-its-kind patented technology, is developed by D&G Machinery. The design has been optimized, taking into account the characteristics and heating characteristics of recycled materials. The rake-type lifting plate ensures the material lifting effect and the drying and heating efficiency, while cutting energy consumption and basically solves the adhesion problem of the RAP dryer drum. The featured "self-cleaning" patented technology greatly alleviates the drum adhesion problem and ensures the system's drying efficiency.
01. Project Cases: Retrofitting of Asphalt Mixing Plant RAP Dryer Drum

Customer's Feedback
The modified self-cleaning dryer drum greatly reduced the occurrence of bonding, with which the customer was very satisfied. There is no need for the workers to carry a pneumatic drill for drum cleaning every day.
02. Background of Retrofitting
During long-term use of the traditional asphalt mixing plant RAP dryer drum, problems such as drum bonding, uneven material curtain, low material temperature, and high exhaust gas temperature arose.
03. Retrofitting Plan
All the above customers are using D&G Machinery's DGXR4500 asphalt mixing plant. In order to help customers settle the many problems during the drum operation, we have retrofitted and configured the "self-cleaning" RAP dryer drum for them.
04. After Retrofitting
Less fuel consumption costs: Based on the analysis of the production conditions at the same construction site, assume the annual usage of recycled materials is 100,000 tons (moisture content: 5%, ambient temperature: 20°C, material temperature: 160°C). If the exhaust gas temperature drops from 195°C to 165°C, the fuel consumption would be reduced by approx.5%, and the thermal efficiency of the drum would be largely improved. In this condition, about CNY 97,500 would be saved per year in fuel consumption costs.
Less manual cleaning costs: Assume the user needs to clean the RAP drum for 5 times per year, and each time 3 people are required for the 5-day cleaning. If the cleaning fee per person per day is about CNY 500, approx. CNY37,500 would be saved annually.
By rough calculation, the savings in fuel and manual cleaning costs are about CNY135,000 per year, which is considerable. If the production volume of the equipment during the time saved by cleaning is also included, namely 320t/h × 8h × 5 days × 5 times = 64,000 tons of finished product, the profit brought by the asphalt mixture is even more considerable.
If you are also troubled by the problem of drum bonding, the low temperature of recycled materials, and the low added ratio of RAP, do not hesitate to contact us. No matter what brand or model your asphalt mixing plant is, D&G Machinery's patented technology "self-cleaning" dryer drum would be of great help.
