　　Shandong RAP Recycled Material Equipment Manufacturer

　　Xibao Heavy Industry actively responds to the national environmental protection call, always pays attention to the technology of asphalt recycling/environmental protection, continuously innovates around customer needs, independently develops multiple environmentally friendly products that meet market demand, and gradually enriches and improves the existing product series. At the same time, we are continuously investing in core technology areas and have formed strong alliances with multiple domestic universities, gathering a group of high-level and high-quality technical talents to provide technical support and assurance for our products. Rooted in and facing the world. Xibao Heavy Industry has always taken "sincere customer service" as the driving force for the company's development, segmenting customer needs and providing customized mechanical equipment. The company's sales and service network covers multiple provinces, cities, and autonomous regions across the country.

　　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.

　　Recycling of old asphalt pavement materials

　　There are usually two methods for recycling old asphalt pavement materials: one is the traditional method of digging up old pavement using combination equipment; The second is to use a milling machine for cold milling. The traditional method is to first use a loosening device to excavate the old road surface, and then collect and ship it uniformly. The excavation of old road surfaces generally uses equipment such as sheep horn rollers, road surface rakers, bulldozers, etc., which are mainly suitable for the full thickness recovery of asphalt pavement.

　　The recycled materials obtained from digging up old road surfaces have a large size and need to be crushed before they can be used for regeneration. They also contain a lot of clay, dust, stones, etc., which need to be processed before they can be used for regeneration. Otherwise, it will affect the quality of the factory mixed hot recycled asphalt mixture.

　　Cold milling is currently one of the more advanced methods for recycling old materials. The advantage of cold milling is that the milled old asphalt mixture does not need to be crushed or has a small amount that needs to be crushed, and can be directly used for regeneration, which is a method of old material recycling. However, cold milling increases the content of fine aggregates.
