Lime Slaking Systems
The ZMI Portec detention slaker produces a highly reactive lime slurry to meet your application needs and maximizes your lime usage.
The Efficient Lime Slaking Solution
Detention type slakers are relatively inexpensive to install and are well suited to applications where lime quality is reliable. The ZMI Portec Detention Slaker from STT slakes quicklime (particle size up to ¾”) and produces slurry with up to 30% solids. This solids concentration allows any lime added to the slaker to be quickly mixed eliminating hot spots from forming. Our detention slaker produces a highly reactive lime slurry to meet your application needs and maximizes your lime usage.
Research has shown that for any given quicklime source, slaking temperature control is the single most important factor influencing the reactivity of the final lime slurry. Our fully automated temperature control provides a highly reactive slurry and minimizes hot spots.
Why Use the ZMI Portec Lime Slaker from STT?
Horizontal agitator breaks the slurry surface preventing dangerous lime ‘cap’ formation
Responds to changes in lime quality and feed rate via an integrated automated control system
Slakes pebble, as well as fine lime up to ¾” and handles water with moderate impurity levels without issues
Vigorous agitation of slaking chamber ensures no dead spots optimizing lime usage
Features And Benefits
|Horizontal rake type agitator||Ensures complete mixing of water and lime, preventing hot spots and maximizing lime usage|
|External water jacket||Preheats incoming water reducing the need for pre-heaters saving on energy costs|
|Round shape of the barrel bottom||Turns over lime due to paddles’ close contact with side walls ensuring thorough mixing|
|Wetting bowl||Creates a water curtain around the dry feed stream preventing lime buildup and upstream plugging increasing efficiency|
|Forced draft wet scrubber||Removes dust and steam saving money on wasted lime and maintenance|
|Stub shaft to agitator shaft connection||Reduces seal packing wear, extending shaft life and decreasing replacement costs|
|Efficient solids and grit handling||Minimizes settling resulting in a high reactive slurry|
|Slaking chambers separated by baffles||Prevents lime short circuiting ensuring fully slaked lime at the outlet|
|Wear liner in slaking zones||Protects the life of the slaking body and is replaceable extending the slaker life cycle|
|External agitator shaft bearings||Minimizes wear and tear due to no contact with lime slurry extending product life|
|Asymmetric packing type seal arrangement||Reduces seal leaks and extends the shaft life improving safety and saving money|
|PLC control system option||Provides a safe and trouble-free operation maximizing productivity|
