Buell dryer
(重定向自Turbo dryer)
The Buell dryer is a multiple hearth direct heated industrial dryer (commonly known as a turbo dryer) that has modified for drying china clay. Its design is very similar to the Herreshoff Kiln, which is a type of calciner. The Buell dryer was first developed by English Clays Lovering Pochin & Co. Ltd for their china clay processing plants in Cornwall. The first Buell was installed in the old cooperage in Nanpean, and was the first operating mechanical dryer in the Cornish china clay industry, having started in 1945.
