The company was started in 1960 by Derek Parnaby who developed the world famous ‘Parnaby Process’ of minerals separation using barrels and cyclones.

In 1974 we started to manufacture the dense medium washing plant which maximises value from coal washing.

During the 1970s and 1980s we developed a comprehensive range of effluent treatment systems.

In the 1990s we began to manufacture mobile units and provide contract services and in the last 10 years we have been pioneering cost effective systems for recycling as an alternative to landfill.

We manufacture almost all the equipment we supply in our purpose built 20,000 square metre site in North East England.
