SUPERCHARGED SCREENING. SUPERSTACK SUPERSTACK
SuperStack®
Derrick Corporation has once again redefined high capacity, high efficiency, fine particle wet screening with the introduction of the SuperStack®. With 8 decks operating in parallel and innovative Front-to-Back (FTB) tensioning system, the SuperStack has a demonstrated capacity up to 3 times that of the best fine screens currently available.
- 8-Decks
- Front-to-Back (FTB) Tensioning System
- Up to 3 Times the Capacity of the Best Fine Screens Currently Available
All of this added capacity comes with only a slight increase in the space required per machine, significantly reducing the total capital and installation cost as well as OPEX for any screening installation.

Features & Benefits
Flo-Divider™
- Equalizes feed flow from source(s) to each deck for optimal separation efficiency
- Dart valves allow flow to be stopped to one or more outlets
Feeders
- Urethane pockets built into each feeder distribute feed slurry uniformly across the entire width of the screen
- Easily removed front cover facilitates maintenance and debris removal
- Interior lining options available for different feed characteristics
Derrick Intergrated Vibratory Motors
- Less than 80dB sound production and rated for continuous-duty operation
- Internal oil lubrication system provides many years of maintenance-free operation
Repulp Spray System
- Increase screening efficiency without increasing deck length
- Spray bars designed to dispense water into repulp wash troughs
- Added free water helps undersize material pass through screen panels
- Replaceable rubber repulp wash troughs
Screen Decks
- Screen beds crowned in the direction of flow rather than side to side, resulting in increased capacity with more effective utilization of the entire screen width
- Time required to replace screen panels is significantly reduced with innovative Front-to-Back (FTB) screen panel tensioning system
