JNWR Energy-Saving King Integrated Asphalt Mixing Plant
1. The Energy-Saving King all-in-one unit incorporates multiple independently developed technologies, delivering significant improvements in weighing accuracy, production efficiency, fuel savings, dust and exhaust emission control, and operational stability. It is ideally suited for road construction projects with stringent requirements for finished asphalt quality and environmental protection. 2. The hot-material bins feature an intelligent, patented design that accurately displays the material level in each bin and automatically controls the supply of cold materials, thereby eliminating overflow of hot aggregates and reducing energy losses. 3. Following numerous experiments and refinements by the design team and R&D department, the recycling equipment has been seamlessly integrated into the asphalt mixing plant’s production process. Building upon the conventional tower-style configuration that combines virgin and recycled materials, the system has been further optimized to achieve an integrated design for both virgin and recycled components, eliminating the need for separate, add-on recycling units. 4. Hot-material recovery employs a physical method to effectively separate old asphalt and old aggregates from RAP, enabling precise grading and management of RAP. This significantly reduces the occurrence of false particle-size measurements and variability in RAP quality, effectively addressing key challenges that have previously limited RAP content and performance. As a result, asphalt recovery efficiency has increased by 40%.

Product Description
Product Features
1. The Energy-Saving King all-in-one machine incorporates multiple independently developed technologies, resulting in significant improvements in weighing accuracy, production efficiency, fuel savings, dust and exhaust emission control, and operational stability. It is ideally suited for road construction projects with stringent requirements for finished asphalt quality and environmental protection.
2. The hot-material bins feature an intelligent, patented design that accurately displays the material level in each bin and automatically controls the supply of cold material, thereby eliminating overflow of hot aggregates and reducing energy losses.
3. After numerous experiments and iterations, the Design Department and the Technology R&D Division successfully integrated the recycling equipment into the production process of the asphalt mixing plant. Building upon the conventional tower configuration that combines virgin and recycled materials, the new design achieves seamless integration of virgin and recycled components, transforming the recycling equipment from a mere add-on to a fully incorporated part of the system.
4. Thermal recycling employs a physical process to effectively separate aged asphalt and recycled aggregates from RAP, enabling precise gradation control of RAP, significantly reducing the occurrence of apparent particle size discrepancies and RAP variability, and effectively addressing and improving key challenges that limit RAP incorporation rates and performance. As a result, asphalt recovery efficiency is increased by 40%.
5. The equipment’s mixing system is positioned beneath the recycled-material metering scale, completely eliminating material adhesion and blockage issues that typically arise when using recycled-material chutes or belt conveyors (with virgin material fed into the mixer via a chute). The integrated design of recycled and virgin materials, combined with an optimized dust-collection system configured directly at the mixer, significantly enhances the overall production efficiency of the entire plant.
6. The entire machine is also equipped with a pre-mixing switching device featuring proprietary patented technology, enabling on-demand selection and switching according to production requirements. Moreover, the mature and reliable thermal regeneration heating technology ensures adequate heating of the recycled material while effectively preventing aggregate adhesion. This approach is energy-efficient and environmentally friendly, delivering significant economic and social benefits.
7. Environmental Protection Measures:
- The main building, dust collection system, and discharge chute are all designed as enclosed structures.
- Centralized collection and treatment of fumes and dust during production
- The main building is equipped with a central vacuum system for convenient daily cleaning.
- The aggregate is supplied via a closed, three-dimensional silo system or a trench system.
- Installation of dust covers and negative-pressure dust collection systems on belt conveyors
