Development workshops

We perform custom-made machine fitting production:

Turning works
Welding
Machine fitting works
Suspension hooks, wall ties and supporting constructions etc.

We produce analytical sieves with standard dimensions (according to ISO 3310, ISO 5223, EN 933; compatibility with sieves of other producers:

Ø 100 mm (frame – stainless steel and brass)
Ø 200 mm (frame – aluminium and stainless steel)
Ø 300 mm (frame – stainless steel)
Ø 400 mm (frame – stainless steel)
500×500 mm (frame – varnished sheet metal)
150×430 mm (frame – wood)

we can arrange the calibration for produced/repaired sieves, including calibration sheet, in calibration laboratory
the sieves have a rubber sealing on the interface of frame and screening partition, which prevents accumulation of sample particles in frame joints and their undesirable release into following sample batches
we repair all sieves made by us, i.e. replacement of screening partition (saving of 40 – 55 % compared to new sieve)
we offer wide accessories for sieves (lids, dishes, reductions, laboratory screening machine, etc.)

Test sieves of metal wire cloth according to ČSN ISO 3310-1 screening partition (sieve bottom): stainless steel cloth mesh size: od 25 μm do 4 mm
Test sieves of perforated metal plate according to ČSN ISO 3310-2 mesh size: square from 1,5 mm to 125 mm round from Ø 1 mm
Test sieves for cereals according to ČSN ISO 5223 frame: Ø 200 mm – aluminium, stainless steel wooden frame, screening partition 150 x 430 mm mesh size: 1,0 – 3,50 x 20,0 mm We supply a dish and a lid as accessories.
Sieves with polyamide screening partition frame: Ø 200 mm – steinless steel, plastic screening partition: polyamide cloth mesh size: 25 μm – 2,1 mm
Grid sieves according to ČSN EN 933-3 frame: 300 x 300 mm – aluminium screening partition: stainless steel bars Ø 5 mm space width 2,5 – 50 mm
Sieves 500 x 500 mm frame: metal plate + komaxit (powder coating) screening partition: steinless steel net, perforated stainless steel metal plate
Sieve accesories Lids, dishes, dish for wet sieving, reduction to pile sieves with different diameters, gauges, etc.
Laboratory screening machine for sieves Ø 200 – P200 type Mobile laboratory equipment for grading analysis of small amounts of granular materials. It is used for dry grading analysis in conjunction with a set of sieves Ø 200 mm according to ČSN ISO 3310 and ČSN ISO 5223.
Plasticity Meter 0-50N It is used for measuring the plasticity of material in the production of autoclaved aerated concrete.
