Howden manufactures and supplies multi-stage high pressure fans (or blowers). These are used in the mineral processing and chemical industries where there is a need to supply relatively small flows at high pressure.
Our equipment is used in many applications. In initial ore treatment
fans are used for washing or percolation in ore leaching to increase airflows, and fans and
blowers are used to provide air for flotation cells.
Smelting of concentrated base metal ores (copper, lead, zinc) is a process in
which fans and the turbo compressors provide air for the
reactions. Centrifugal fans exhaust the gases from the converters and
The sulphur dioxide gas produced from smelters is now
increasingly captured and converted to sulphuric acid; turbo-compressors are
also key components in sulphuric acid production.
We are major suppliers of fans for alumina refineries and aluminium smelters.
Removal of the plant fumes is essential for environmental control.
