en.Wedoany.com Reported - The HZS120 box-type concrete mixing plant from Fangyuan Group was recently installed, debugged, and put into operation on the Tongwei section of the Gansu S35 Jingtai to Lixian Expressway. This plant has a theoretical production capacity of 120 cubic meters per hour, with a nominal mixing host capacity of 2.0 cubic meters.
Fangyuan Group is headquartered in Haiyang, Shandong, and specializes in complete sets of concrete mixing equipment. The HZS120 model adopts a box-type modular structure, where each unit module is embedded within an independent box-type frame, significantly reducing installation and disassembly time compared to traditional designs. Aggregate lifting utilizes a high-inclination belt feeding system, which occupies a small footprint and offers high conveying efficiency. The control system enables fully automatic adjustment of mix proportions, with aggregate measurement accuracy of ±2%, and powder and water measurement accuracy of ±1%.
The S35 Expressway is part of Gansu Province's "Three Major New Expressway Corridors" project, specifically the southern main corridor. Upon completion, it will connect regions such as Jingtai, Jingyuan, and Pingchuan, enhancing the traffic capacity of the national trunk highway network. The Tongwei section is a high-grade mountainous highway with dense bridges and tunnels, placing high demands on continuous concrete supply and mix proportion stability.
The HZS120 mixing plant is equipped with a twin-shaft forced mixing host featuring anti-stick shaft technology and a pressurized spray water discharge device, reducing the frequency of host cleaning. The plant body uses an enclosed structure paired with an active dust collection system. Residual concrete can be recovered, separated, and reused. Dingxi is located at a core node of the New Eurasian Land Bridge. Once the S35 Expressway opens to traffic, it will strengthen the connectivity of the road network in central and southern Gansu.
