　　Asphalt pavement crushing equipment, waste asphalt recycling material equipment, video and pictures

　　Since its establishment, Xibao Heavy Industry has been focusing on providing customers with competitive equipment solutions and services in the field of asphalt mixing/recycling. Our product development and manufacturing cover multiple product series, including asphalt mixture mixing equipment, asphalt plant mixing and hot recycling equipment, waste asphalt mixture crushing and screening equipment, asphalt warm mixing equipment, etc. Among them, the asphalt plant mixing and hot recycling equipment has gained high recognition from industry customers due to its technological advantages!

　　With a large amount of asphalt waste material (RAP) being reused, more and more customers are paying attention to equipment in the field of asphalt recycling, and the demand for related equipment has doubled accordingly. Jiangsu Xibao Heavy Industry, as a rising star in the field of asphalt recycling, has attracted a lot of attention from customers for its independently developed recycling products.

　　From this year's equipment sales data, it can be seen that the XB series asphalt waste crushing and screening equipment from Xibao Heavy Industry has been exceptionally popular in sales. As of now, it has been put into use in provinces and cities across the country such as Zhejiang, Jiangsu, Anhui, Xinjiang, Hubei, and Beijing, and has been exported to overseas countries such as Vietnam, helping RAP to recycle and achieve resource regeneration.

　　What are the advantages of XB series roller crushing and screening equipment?

　　The XB series is a specialized crushing and screening product launched by Xibao Heavy Industry based on its rich design experience in asphalt plant mixing and hot recycling equipment, combined with the particularity of domestic RAP material acquisition methods. The equipment adopts flexible separation technology combined with high-frequency screening technology to ensure the gradation control requirements in the production process of RAP mixture with high mixing ratio. The flexible crushing and screening method avoids the secondary damage of RAP grading, and the high-frequency screening technology can screen RAP below 4.75mm, ensuring the control of the proportion of fine materials in the mixture grading.

　　RAP flexible crushing and screening "3-step method":

　　1. First level single roll flexible separation

　　The crushing roller of the single roll primary crusher works in conjunction with the hydraulic driven pushing device, resulting in high crushing efficiency. Low speed combined with a movable buffer plate can achieve flexible separation. The wear-resistant parts on the crushing roller adopt the standard cutting head of the milling machine, which has good wear resistance and is easy to replace.

　　2. Grading system

　　The high-frequency vibration motor is used as the driving force motor to drive the screen mesh to vibrate (the screen body does not move), solving the problem of RAP material blockage below 4.75mm and achieving high-speed tapping of materials. This structure combines the conventional vibrating screen and vibrating screen into one, and one vibrating screen can separate three types of materials, reducing equipment occupation and saving costs.

　　3. Secondary roller type flexible separation

　　The double roll secondary crusher is equipped with two sets of crushing rollers arranged in a cross pattern. One of the crushing rollers is equipped with a spring tensioning device, which can adjust the gap between the crushing rollers to achieve the adjustment of material particle size and output after crushing. Compared with hammer crushing and impact crushing, roller crushing causes less damage to the gradation of RAP raw aggregates. The roller speed is low and the crushing method has minimal impact, greatly extending the service life of the equipment. At the same time, there is almost no dust generated during on-site work.

　　During the renovation process of old roads, a large amount of waste materials will be generated, which still have high utilization value as road materials. Therefore, the recycling of old materials is also considered as one of the major overhaul plans.

　　Asphalt pavement regeneration technology is a set of process technologies that involves excavating, recycling, crushing, and screening old asphalt pavements that need to be renovated, and then re mixing them with rejuvenators, new asphalt materials, new aggregates, etc. in a certain proportion to obtain a regenerated asphalt mixture that meets certain road performance requirements, and then re paving the pavement with it. Through road surface regeneration, not only can it meet the requirements of road performance again, save a lot of material resources and funds, reduce engineering costs, but it can also avoid environmental pollution caused by waste materials, achieve industry circular economy, and promote ecological environment protection. It is a specific practice of implementing the "conservation oriented society" strategic measures, which has significant social and economic benefits.

　　According to the different mixing and construction temperatures of recycled mixtures, asphalt pavement recycling can be divided into cold recycling and hot recycling. In the cold recycling process, the old road milling, mixing and paving of new and old materials are carried out at room temperature, and the cold recycling binder is usually emulsified asphalt or foam asphalt; During the hot recycling process, heating is required for milling the old road surface and mixing new and old materials.

　　According to different construction scenarios and techniques, asphalt pavement recycling can be divided into factory mixed recycling and on-site recycling. The difference between on-site regeneration and factory mixed regeneration lies in the location where the mixing process occurs. The mixing process for on-site regeneration takes place on the old road surface, while the mixing process for factory mixed regeneration takes place at the mixing plant.

　　In road surface overhaul projects, commonly used regeneration schemes include on-site cold regeneration, factory mixed cold regeneration, on-site hot regeneration, and factory mixed hot regeneration. Each regeneration technology has its own characteristics and is suitable for different road conditions. Before recycling, conduct a detailed investigation and analysis of the road surface condition, and select a recycling plan to achieve benefits.
