V’Sepa Air Screen Range
Precise, fine segmentation and dust removal.
The Kemco V’Sepa quad-deck screen enables high throughput precision screening of aggregates.
The unique design combines the accuracy of mesh screens the advantages of high air flow systems. It is designed to process <40mm material, but offers particular advantages processing aggregates containing high levels of fines (e.g. <3mm).
V'Sepa benefits
Higher processing rate – 2x-10x the throughput of conventional screens is commonplace.
Accuracy – Ultrafines are removed before material hits the screen media, enabling high accuracy down to 0.3mm mesh. Ultrafine levels in the product can be precisely controlled.
Slash water demand - Uses no water for removing ultrafines, ideal for de-dusting manufactured sand for use in concrete
No dust – A encapsulated operating under negative pressure means the plant gives off no dust, even with the doors open!
Versatility – Options for up to 7 different product fractions simultaneously, ranging from 40mm to <0.075mm.

Table Notes
- Actual performance determination is carried out by screening test.
- Required power does not include the ancillaries such as a compressor for the dust collector.
- Capacity may vary with feed gradation, separation size, moisture, etc.
- The above guide capacities can be expected with dry feed material of bulk density 1.6t/m3
Example Plant Configuration
- Number of air screen outlets depends on customer requirements.
- Skimmer is optional and only used for separation.
- Bucket elevator is optional and can be replaced with a longer feed conveyor.
- Extractor fan also sucks from covered conveyors and bucket elevator to provide complete dust suppression in the plant.
Example applications
- Tertiary screening to separate up to 40mm aggregate into product categories and remove ultra-fine dust.
- Removing large particles from fine materials such as Quicklime or Cement, with accurate cuts down to 500µm.
- Precision screening of particle sizes for specific applications such as bead blasting.
- Extraction of high value fines, such as glass fine-grind.
- Extraction of contaminates, such as paper in recycled glass.
