How a Peeler Centrifuge Works
Peeler centrifuges are batch centrifuges and usually possess perforated filtration bowls in which cloth filters are used. The liquid in the admitted suspension is centrifuged and filtered at high speeds during which the solids form on the cloth filter in the shape of filter cakes. Once they have been spun-dried, these filter cakes are scraped out on a batch basis by peeler knives inserted into the rotating bowl. The solids may be washed before removal. Peeler centrifuges may, for example, be employed to achieve maximum removal of moisture from solids which have to be as pure as possible or with suspensions that cannot be separated by their different densities.
