Quarrying

Parnaby Cyclones manufactures and installs a wide range of equipment for the washing, separating and classifying of different grades of sand and aggregates.  We also supply effluent treatment systems.

We use classifying cyclones (also known as sand cyclones) and high frequency dewatering screens to recover sand down to 75 microns particle size.

Lignite removal

Where required we can provide equipment to separate lignite from sand.  This improves the quality of the sand, especially for use in concrete, and recovers another product for sale.  We recommend the use of natural medium cyclones to remove lignite from sand of particle size 1-5mm and a hydrosizer for fine sands below 1mm particle size.
