Scrap Drying & Preheating
For some melting processes it can be a necessity to remove water or ice from scrap materials before being discharged into a furnace, therefore a method of scrap drying can sometimes be an essential requirement for operator safety. As part of a drying process, certain benefits gain be gained to preheat the scrap which can significantly increase productivity in melting operations. We manufacture Drying / Preheating Systems which are divided into the two following categories.
- Scrap Tumbling System
- Gas Fired Drying and Preheating System
Gas Fired Drying and Preheating Systems
The base of the tunnel comprises of a vibratory feeder to provide the conveying motion and the top of the tunnel is a separate static hood independent of the feeder which incorporates high velocity gas flame burners pointing vertically downward onto the scrap under. Heating the scrap will melt any ice present and drive surface moisture away which could cause unwanted water/molten metal interaction.
In addition to drying charge materials, these units may also go a step further to preheat charge materials which would reduce the energy and time needed to melt them in a furnace.
Scrap Tumbling System
The water is discharged through perforations in the drum which can be collected and directed away.
This system is purely mechanical and is more appropriate for lighter non-ferrous scrap materials which is purely used to remove water from pockets or chambers within the scrap.
