Tina River Project Concrete plant ready to be commissioned
HONIARA – The Concrete batching plant for the Tina River Hydropower Development Project has gone through its final installation work and is expected to be in full operation by January 2023.
Manas Ranjan Samal, Hyundai Electrical Engineering (HEC) Electrical Manager confirmed that the installation of the concrete facility is almost complete and will soon begin the process of testing and commissioning.
“We are now completing the electrical works and testing will commence in the coming weeks for commissioning.”
The plant will produce different grades of concretes for various works based on the mixed design taking into consideration the concrete slump, grade, and efficiency. Mixed design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures.
The concrete batching plant process flow begins from the feeding of aggregates into individual bins depending on formation size.
“These aggregates will be weighed individually as per the design set in the control panel. After weighing, they will be transferred to the mixing unit. Above the mixing unit, are weigh hoppers for cement, admixtures and water.
“The job of the weigh hopper is to weigh and then transfer the contents into the following mixing unit. Cement is transferred to the weigh hopper employing a screw conveyor. Water is pumped up into the weigh hopper. After mixing for a specific time as set by the mixing unit, the mixer will discharge the contents into a transit mixer to be transported to the construction site.”
