Screens and Sieves

Parnaby Cyclones have extensive experience in the design and manufacture of a wide range of vibrating
screens for applications in the coal, aggregate, waste and recycling industries.

All screens are constructed with heavy-duty box section sub-frames, heavy duty side plates, wear plate lined
feeding and discharge boxes. They are available with a wide range of screening surfaces for sizing and
dewatering applications.

The screens are painted with two coats of single pack polyurethane; alternatively the
screens can be coated to the customer’s specification. Vibratory motor and geared mechanism options are
available.

VIBRATORY CURVED SIEVE BEND UNIT More info..
Vibratory curved screens can be used to size and dewater many materials including coal, sand and food
products. Many different screen sizes are available - the finest can dewater particles as small as 150 micron.
Screens can be supplied in mild steel or stainless steel or with polyurethane coating.

LIVE DECK SCREENS More info...
Parnabys can supply this specialist type screen for separation (dry basis) of fine particles ie these screens can operate / separate as low as 2mm particle size with exceptional efficiency.

How it works - elastic polyurethane screen panels are alternatively tensioned and relaxed. In the tensioning phase the panels are actually stretched and the holes are elongated which frees any stuck particles from the surface of the panels, vastly improving screening efficiency over any concentrated screen.
Screens of 1m x 2m through to 2.4m x 8m long can be supplied to handle a wide range of feed rates and different materials.
