Derek Parnaby Cyclones was started in 1960 by Derek Parnaby who developed the world-famous ‘Parnaby process’ of minerals separation using barrels and cyclones. In 1974 Parnaby Cyclones started to manufacture the Parnaby dense-medium washing plant, which maximises value from coal mining.

Dense-medium washing plants for coal mining

Derek Parnaby Cyclones is an English company, still owned and run by the Parnaby family from their factory based in the North-East of England.

Parnaby Cyclones is one of the few remaining companies who design, manufacture and trial assemble all of our processing plant and equipment in-house, allowing to keep a close eye over our exceptionally high-quality standards.

Washing and separation plants for coal beneficiation

Parnaby Cyclones has strived to develop a large and comprehensive range of washing and separation plants, which are now in use all over the world, mainly working on coal beneficiation, allowing our customers to achieve much higher value yields from their raw coal extraction. 

Many Parnaby Cyclones plants come complete with a Parnaby full effluent treatment system, allowing the recycling and re-circulation of the washing water required in the washing and separation process. This, complete with high-efficiency drives, and magnetite recovery systems, make running a Parnaby plant very economical.
