Xizhu environmental protection and energy-saving asphalt mixing equipment is in short supply

Since the start of this year, large-scale asphalt concrete mixing equipment manufactured by Xi'an Road Construction Machinery Co., Ltd. has gained significant market popularity and user satisfaction. The J series (container type) and H series (environmentally friendly and energy-saving type) have taken the lead in the domestic industry, with the H4000 model being particularly well-received. To date, over 20 units of the H4000 environmental and energy-saving asphalt mixing station have been sold. In just the first five months of this year, 8 units were sold, generating nearly 100 million yuan in revenue, and the current demand is still outpacing supply. With China's rapid economic growth and expanding highway construction, the technical requirements for asphalt mixing equipment are becoming increasingly stringent. Environmental protection has also become a top priority. The H series equipment significantly improves on pollution control, noise reduction, energy efficiency, and precision compared to older models, meeting and even exceeding national urban environmental standards. According to the China Construction Machinery Information Network (6300.net), the equipment is an internationally advanced environmentally-friendly and energy-saving system developed through collaboration between Xizhu and Germany’s BEN-NINGHOVEN (Benninghof). With a capacity of over 320 tons, the first unit was introduced in 2001, marking the beginning of China's first asphalt mixing plant. The specially designed bag dust collection system achieves a dust removal efficiency that meets European emission standards, with emissions below 15mg/Nm³. Insulation measures on components such as the drying cylinder, hot silo, and asphalt system ensure high thermal efficiency, while the energy-saving system guarantees precise material weighing—±0.3% for aggregates and ±0.2% for asphalt. The newly designed drying cylinder features a compact structure, easy adjustment, and high thermal efficiency. The advanced Hoff burner can burn a wide range of fuels, and the intelligent central computer control system ensures both accuracy and ease of operation. This equipment embodies the integration of high technology and humanized design, making it a true masterpiece in road construction machinery. The J series (container type) not only offers the same energy-saving and eco-friendly features but also incorporates a modular design, making installation, transportation, and operation more convenient. To better serve China’s high-grade highway construction and meet diverse regional needs, Xizhu Company has invested heavily in localization and technological upgrades. In April 2005, the H series environmentally friendly and energy-saving asphalt mixing equipment passed the Ministry of Communications’ technical appraisal. Experts praised its advanced technology, reasonable design, and reliable performance. Compared to similar domestic models, its energy-saving and environmental benefits are clearly evident, with main technical performance reaching international advanced levels. Currently, these two product lines offer three configurations—high, medium, and low—to meet different user needs, and they hold a significant market share. They play a crucial role in China’s high-grade highway construction. It is reported that the J4000 model, which corresponds to the H4000 environmentally friendly and energy-saving asphalt mixing equipment, is currently under development and is expected to become another highlight in the construction machinery industry.

Originally known as the Xi’an Road Construction Machinery Factory, it was directly affiliated with the Ministry of Communications. After the separation of government and enterprise, it came under the leadership of China Road and Bridge (Group) Corporation. In 1999, some of the high-quality assets, including the factory, were used to form Luqiao Group International Construction Co., Ltd., which was listed on the Shenzhen Stock Exchange. On December 8, 1999, the factory reorganized its assets into Xi’an Road Construction Machinery Co., Ltd. The company employs over 1,100 people, including more than 200 engineers and technicians. Sales reached 300 million yuan in 1999. Over the past 40 years, the company has continuously introduced and absorbed foreign advanced technologies, accumulated extensive experience in the design and development of road machinery, and now offers five major product lines: asphalt mixing equipment, asphalt pavers, stabilized soil mixers, maintenance machinery, and crushers. It has developed over 20 varieties of pavement machinery products and related equipment, becoming one of the largest and most complete enterprises in China. Since 2000, the company has launched a new round of technical upgrades, focusing on developing environmentally friendly asphalt mixing, cement mixing, paving, and asphalt maintenance equipment. Alongside technology introduction, the company has intensified its internal technological transformation, purchasing advanced domestic and foreign equipment such as laser cutting machines, shot blasting systems, and welding robots, and establishing hydraulic testing benches and electrical test rooms. It has also improved its testing and quality assurance processes. The company has introduced modern design tools such as Hewlett-Packard’s 9000 Series 715 workstations, ME10 2D engineering drawing systems, ME30 3D CAD manufacturing software, and EDS.UG.CAD. Through the implementation of the National 863 Program CIMS project, it has set up the largest Gigabit Ethernet network in the northwest, along with an advanced, practical, and reliable computer-integrated manufacturing system. The company is currently working with Hong Kong Best Technology Integration Co., Ltd. to develop the iCom21 corporate e-commerce system. Xi'an Road Construction Machinery Co., Ltd. has always adhered to the "customer-first" principle. Its products are sold across 30 provinces, municipalities, and autonomous regions in China and have been exported to over ten countries and regions, including South Korea, Singapore, Hong Kong, and Yemen. The company has earned a strong reputation for quality and service. It has received the “Contract-honoring and Promise-keeping” title in Shaanxi Province for many years and was awarded the “User Satisfaction Certificate for Quality of Service” by the National Quality Association User Committee. In 1998, the company successfully passed ISO9001 quality certification.
