Over the years, the plant had undergone regular maintenance and several major rehabilitation, replacements and upgrading particularly on its dust control system, conveyor system, aggregates dryer, vibrating screen, pug mill/mixer, computerized weighing system and control room.
In the years 2004-2005, the entire dust control system was completely replaced with new filter bags and bag house. New load cells were installed for a more efficient weighing system. Computerization in the control room was also upgraded.
The old system of decanting bitumen in drums and manual heating in kettle house were completely eliminated. The more efficient direct heating and electronic transfer system from cylindrical ISO tank deliveries to the existing bitumen tanks are now being implemented. |
