Slurry Mizers

Where Used:
Liquid slurries, with contaminants ranging from parts per million to several percent, are generated in a broad range of metal working and metal finishing operations. Evaporating the liquid, usually water, to produce a dry granular material can reduce disposal costs as much as 20 : 1.

Sources of slurries include:

• Settling tanks or clarifiers.
• Water from washing or rinsing.
• Coolants from grinding.
• Regenerants from ion exchange systems.
• Concentrate from reverse osmosis systems.
• Vibratory finishing water.
• Concentrated brine from atmospheric evaporators.

Operating Principles:
Liquid slurry is pumped into a liquid tight trough. Heat is indirectly applied, using steam, hot water or electricity. A rotating screw mixes the slurry, preventing formulation of a moisture trapping layer on the surface, while preventing a buildup of dried material on the heated surface. Drawing off the moisture forms a significantly smaller quantity of dry granular material which is dumped by opening a liquid tight discharge door.
