The National Research Institute of Mechanical Engineering has successfully designed, manufactured, and erected a 300-ton/hour bulk cement loading station, meeting requirements for quality, safety, and schedule...

Dr. Vu Van Khoa, Deputy Director of the National Research Institute of Mechanical Engineering (Ministry of Industry and Trade) stated that, in order to capture the market share of the domestic cement market for the Central region and the Mekong Delta, Nghi Son Cement Company (NSCC) has a need to construct several bulk cement distribution stations, including: the Hau Giang Cement Distribution Station (Song Hau Industrial Park, Dong Phu Commune, Chau Thanh District, Hau Giang Province) and the Chu Lai Cement Distribution Station (Chu Lai Port - Truong Hai, Tam Hiep Commune, Nui Thanh District, Quang Nam Province) with the following requirements: Storage capacity: 7,000 tons of cement; the station must be able to receive cargo ships ≥ 10,000 - 30,000 tons; the station must have a cement loading capacity of 300 tons/hour.

Hau Giang Cement Distribution Station

The project was constructed at the Hau Giang Cement Distribution Station (Song Hau Industrial Park, Dong Phu Commune, Chau Thanh District, Hau Giang Province) and the Chu Lai Cement Distribution Station (Chu Lai Port - Truong Hai, Tam Hiep Commune, Nui Thanh District, Quang Nam Province) of Nghi Son Cement Company.

The system can perform automatic loading and manage loading data, and the company can also conduct full-time online monitoring. At the same time, it ensures absolute safety during station construction; the station must meet local environmental standards at the construction site.

Leveraging its capabilities in the cement sector, the National Research Institute of Mechanical Engineering has successfully undertaken the design, manufacture, and erection of a 300-ton/hour bulk cement loading station. Specifically, the Institute calculated the technology for receiving cement from ships via a steel pipeline system approximately 1,000m long; the pipeline routing scheme to meet the investor's supply pumping requirements; the silo bottom material extraction system for transporting and loading bulk cement into tanker trucks; the station's automation control system; and a baghouse dust filtration system to ensure that the cement intake/loading process does not cause dust dispersion affecting the surrounding environment.

Furthermore, the Institute established the PLC S7-300 control software and the SCADA Win CC control software for the distribution station. Information is automated and monitored online full-time both at the Distribution Station and at the headquarters of Nghi Son Cement Company in Hanoi.

According to Dr. Vu Van Khoa, the equipment of the Cement Distribution Station achieved the most modern standards and the steel silo had the largest capacity in Vietnam (over 3,500 tons) at the time of project completion. Along with that, the cement receiving pipeline system has a capacity of 400 tons/hour; the bulk cement transport and loading system for tanker trucks achieves a capacity of 300 tons/hour.

The successful implementation of the project has contributed to reducing foreign currency expenditure that would have been paid abroad if all equipment were imported. This system can be applied to all industries requiring the transport of powdered or granular materials.

"By supplying cement distribution stations to Nghi Son Cement Company (a joint venture between Japan and Vietnam) with stringent requirements for quality, safety, schedule adherence, and competitive pricing, the National Research Institute of Mechanical Engineering has affirmed its EPC general contractor capabilities in design, manufacturing, supply, installation, and project management for projects demanding high standards of quality, safety, and schedule compliance." - Dr. Vu Van Khoa affirmed.

The design, manufacture, and commissioning of these distribution stations also help the National Research Institute of Mechanical Engineering add a research product that has been commercialized in the field of cement transport as well as the transport of other small granular materials.

In the aforementioned projects, the National Research Institute of Mechanical Engineering localized approximately 80% of the technological equipment value. For some high-tech equipment, the National Research Institute of Mechanical Engineering is coordinating with several domestic companies to find ways to localize them. To achieve this, NARIME hopes that the Ministry of Industry and Trade and the State will provide support so that the Institute can successfully research, design, and manufacture them.
