September 16, 2022，Organized by China Construction Machinery Industry Association“DGXRResearch and Application of Key Technology of Asphalt Mixing Plant”The appraisal meeting of scientific and technological achievements of the project was held in Langfang Deji Machinery Technology Co., Ltd.。Road Construction and Maintenance Machinery Branch of China Construction Machinery Industry Association presides over the appraisal work。Follow the process，Experts from relevant industries were invited to form an appraisal committee.，According to China Construction Machinery Industry Association《Administrative Measures for Appraisal of Scientific and Technological Achievements》And projects《Identification outline》Request，The project was identified and evaluated.。The appraisal committee listened to the design, development and trial production report of the project team.，All the appraisal documents were consulted.，Reviewed the quality inspection report of the equipment、User usage report and novelty search report，The processing was investigated、Craft、Experimental and other conditions，After research and discussion，The appraisal of the scientific and technological achievements of the project was unanimously passed.。

The appraisal opinion holds that，The results of the project are innovative.，The technical difficulty is great。Have completely independent intellectual property right。The research and development is successfulDGXRSeries of mixing equipment“Building blocks”Modular Seamless Switching Technology with Flexible Configuration，The standard function expansion module and interface specification are established.，Developed“Fly over the cloud of wisdom”Intelligent interconnection information service system, etc.。The overall technological achievements have reached the international advanced level.。 

Appraisal meeting site

DGXRSeries asphalt mixture mixing equipment is a self-developed project of Deji Machinery.。Deji Machinery has been engaged in the research and development of asphalt mixing equipment for more than 20 years.，Attract、Trained a large number of technical personnel，Deposited a solid technical foundation，Accumulated rich development experience。Its various types of equipment, whether from metering,、Heating、Stir、Smoke and dust removal, etc.，Or from energy saving、Regeneration、Warm mix and other links，The production quality of the asphalt mixture and the individual requirements of users for the mixing equipment can be ensured.。Asphalt mixing plant is a large engineering equipment for mixing station。In the actual construction project of the user，If there is any uncertainty about the use of recycled pavement materials in the near future，The selection and configuration of equipment is expected to be able to carry out modular interchange according to the actual engineering development.，And most of that cost is save，Shorten the conversion period。This is a representative demand of the market.。A few years ago，The R & D team of Deji Machinery has keenly captured this hot spot in the market.，Put forward according to the characteristics of the equipment：To ensure the quality of regeneration、On the premise of technical requirements such as mixing quality and environmental protection emission，So that various types of equipment to achieve modular seamless switching，Take into account the conventional type、Integral type，Comprises units such as a bottom finished product bin, a side finished product bin and the like.，Adopt“Wuhua”Design concept（Standardization、Generalization、Modular、Intelligent、Beautify），Achieve“Cross-model、Across models”Upgrading requirements for modular assembly interchange of a full range of products。In the project，They innovatively abandoned.“Compactness”Design principles，Designed through a standard modular architecture that maximizes，MakeDGXRThe series of products have realized the functional modular interchange.、Spacious space for installation, commissioning and maintenance，Save a lot of purchasing.、Warehousing、Transportation、Installation cost，Comply with green product design principle，And ensure that quality of installation and debugging.。

The project R & D team is based on the technology accumulation of Deji Machinery for many years.，After one year's scheme design and prototype trial production,，The plan requirements of the project task book have been basically completed.。It has passed the real machine test of the inspection and testing organization，The performance and function of the equipment meet the requirements of the task book and relevant standards.。After more than a year of continuous improvement and more than a dozen user projects to verify the actual use.，Fully meet the planning requirements of the project design，Be welcomed by users。This project has obtained more than a dozen utility model patents.，And two invention patents have been accepted.。So，The project team completes the acceptance within the company.，An application for achievement appraisal was submitted to the China Construction Machinery Industry Association.。

The appraisal committee fully affirmed the research and development direction of the project.，Give a high evaluation of the project results.。Think，Deji Machinery is ahead of the industry in terms of ease of use and market affinity of asphalt mixing equipment.。During the inspection，Laser cutting and blanking、Robot welding and other processing conditions and warm mix laboratory、Flexible crushing and separation equipment for recycled materials has been praised by experts.。

Congratulations to Deji MachineryDGXRSeries of asphalt mixture mixing equipment has achieved fruitful results.！

I hope Deji Machinery will make persistent efforts.，Continue to explore the deep demand of the market，Maintain superior performance、Smart and easy to use、Energy saving、Environmental protection、“Carbon reduction”The general direction，Continuously introduce new equipment with new functions，Meet the various needs of the market，To make greater contributions to the high-quality development of the industry，The overall technology of asphalt mixing plant in China has been pushed to the forefront of the world.。
