. Pansep - the world's finest particle screen

Pansep™ mesh development
Here we compare the specially developed and patented mesh for the Pansep screen, with prior technology. Standard mesh from Pansep provide very high open areas and accurate apertures and cut points from 50 - 2,000 micron. We'll gladly develop special meshes for your particular application.

Patented screening cycle

The PANSEP™ moves a series of patented pneumatically tensioned industrial mesh screen panels around in a circular motion without bending the mesh.

Two screenings in one cycle:
A. TOP SCREENING PASS

1. First feed
Slurry is distributed evenly and gently onto moving deck of pans which have been previously washed and de-gritted. Feeds on the top and bottom run, double capacity and make the Pansep self-cleaning. Unique feed design ensures even distribution of slurry. 

Five patents cover: 1. Principle of operation 2. Drive system 3. Mesh tensioning 4. Slotted mesh screens 5. Spray bars

2. First screening
While moving, patented pneumatically tensioned mesh panels screen slurry at designed cut point. Undersize falls through, oversize stays on top of mesh. The patented screening method uses specially designed slotted meshes with high (+40%) open area. Screening is assisted by using special, patented spray bars. The spray water is used to maximize undersize solids recovery and to minimize misplaced undersize solids in the oversize discharge. The water is also used for fluidization of the solids on the mesh.

3. First oversize discharge
After screening, oversize is discharged and sprayed off the panel into a special chute. (For dry discharge air knives are used.)

4. First cleaning
After discharging oversize, each screen panel is rinsed of all particles using special patented spray bars that spray from the inside out (reverse direction of slurry feed.) Rinsed, clean panels rotate around and are again presented to incoming slurry ... the Pansep's second screening starts.

B. BOTTOM SCREENING PASS
Slurry is fed to the bottom feed box which distributes the slurry onto the bottom moving deck of pans. The screen area that was previously on the bottom side of the pans in the top side screen pass, now becomes the screen area in the bottom side screen pass. The undersize cut of slurry drains through the mesh. The oversize cut is retained on the mesh and then discharged into the bottom pass oversize chute located on the inside of the Pansep screen. After discharge and cleaning with spray bars, the inter-linked pans rotate around.

 Rinsed, clean panels rotate around and are again presented to incoming slurry ...
the Pansep's cycle of 2 screening passes starts again.

UNIQUE FEATURES

Self-cleaning
Panseps are self-cleaning because it screens in both directions and uses cleaning spray bars to wash any residual oversize off - before screening again.

Patented Mesh
All meshes are 316 stainless steel and slotted to allow higher screening open area (+40%) and fast drainage. Slotted mesh results in far less pegging and blinding. Accurate screen mesh apertures are guaranteed. Thicker wires can be used to prevent abrasion and damage. All meshes are pneumatically tensioned in all directions through a patented design, preventing creasing and increasing mesh life three-fold.

High throughput
Slotted mesh with high mesh open area, combined with the Pansep's unique way of feeding slurry onto a moving "train" of mesh panels, results in very high throughputs.

Positive screening
The Pansep's design virtually guarantees that no oversize particles are misplaced into the undersize.

Spray bars
Screening is assisted by using special, patented spray bars. Patented design can introduce water straight up from underneath or diagonally down onto the mesh. The spray water is used to maximize undersize solids recovery and to minimize misplaced undersize solids in the oversize discharge. When spraying upward, the water is used for fluidization of the solids on the mesh.

Low power consumption
No vibration, combined with the special drive system make for extremely low power requirements. (A 9m² production Pansep can be rotated by hand.) Panseps are exceptionally economical and efficient.

Low maintenance
Patented drive systems result in virtually maintenance-free operation. All meshes are pneumatically tensioned in all directions through a patented design, preventing creasing and increasing mesh life three-fold.

Small footprint
Dual feed decks (upper and lower) result in exceptionally small footprint - less than half of the equivalent vibratory screen.
