Q: How does a sludge dryer work?
Our continuous sludge dryer is designed to be used in conjunction with a filter press, which dewaters metal hydroxide slurries from metal plating operations.
- The filter cake that is produced by the filter press is dumped into the sludge dryer receiving hopper (A).
- Wiper blades push the filter cake through a stainless-steel screen, decreasing the material’s size and shaping it for increased surface-area and efficient drying (B, C).
- Next, the noodle-shaped material falls onto a continuous stainless steel mesh belt, where it passes under a series of infrared heaters for drying (D).
- The heat is produced by natural or LP gas, while ambient air is drawn through the heat chamber by a fan mounted on the inlet of the wet scrubber (E).
- After significant reduction, the dry, granular material exits the dryer into a container for removal.
