Turmec Engineering was selected to take on the project, due to the extensive knowledge and experience in this field. The intricate project currently being commissioned, will include the following:
- Scalping screens
- Independent feeders
- Trommel screen
- Eddy Current
- Multiple bay storage conveyor system
The process used a complex conveyor shuttling system so that the ash can be stored in any one of 5 storage bays. Being unique to the project, the belt was reinforced to transport hot ash, withstanding heat up to 500 degrees. A different scraper was also needed for the abrasive material.
Materials are passed from feeder to the trommel screen, before the over size is scalped off which is anything 35mm plus & magnet, ferrous recovery & non-ferrous recovery.
Fine fraction falls through trommel and is passed under an electro magnet to remove the ferrous fraction. This is collected in a storage bin underneath. Once the ferrous fraction is removed, the ash is then passed over an eddy current separator, where the non-ferrous is ejected and collected in another storage bin underneath. The remainder of the ash continues over towards maturation bays, which uses the same shuttling system over drying bays.
