Because the plant is designed on a modular basis with sections inside standard shipping containers, this allowed faster commissioning as well as a number of other cost savings for the client.
With an output of up to 320tonnes/hour, the Lintec CSM4000HS20-SE asphalt batching plant has helped the contractor to meet pressing demands for material supplies to several prestigious projects over the past 18 months.
Based in China’s eastern Zhejiang province, Ningbo Heng-Shun Traffic Engineering Co took delivery of the containerised plant, the second-largest in the Lintec line at the end of May 2019. The modular construction meant that by the middle of June 2019 the plant was ready according to schedule, typically mixing over 3000tonnes of asphalt during a standard 10-hour shift.
Materials from the plant have been delivered to a host of the contractor’s regional projects. This has included the phase four expansion project of Ningbo Lishe International Airport as well as for numerous surrounding highways.
Ningbo Heng-Shun selected the Lintec plant in 2019 after travelling to the construction site of the Hong Kong-Zuhai-Macau bridge, where another CSM4000 had just completed the job. Seeing the faultless performance of the plant on this high-profile, heavy-duty project sealed the deal for Ningbo Heng-Shun’s leadership.
The company noted there were several design features that appealed to its needs. The operating system provided precise weighing of the aggregate and bitumen ratio, which has saved a significant quantity of bitumen. The firm also opted for corrosion- resistant paint as an option, which has given effective environmental protection against the humid and often harsh climate of the East China Sea coast.
Environmentally friendly performance was also crucial as the plant is based close to city centre areas. To meet these needs, Lintec’s standard pollution control unit, which recycles dirt particles into reclaimed filler rather than emitting them into the air, has proved essential.
The shipping container structural design provided a further benefit through its simple, low-cost transportation and assembly.
Once a plant has begun operation, a Lintec engineer offers onsite technical support to ensure optimum production, with full operator training also provided as was the case for Ningbo Heng-Shun.
Lintec engineers are also able to log-in to the operating system of any unit, to provide 24/7 remote technical support. This allows them to make rapid diagnoses of any issues to ensure the plant operates at maximum efficiency.
