Basket Centrifuges are the simplest and inexpensive centrifuges available. They are primarily used for solid/liquid separation but some liquid/liquid separation is possible with some units.
Two types of basket centrifuges:
1) Perforated Basket Centrifuges require the use of a filter media or filter bag in the rotating basket. Feed material is dumped into the rotating basket and liquid flows through the filter media and perforated basket. Solids are collected in the basket. Solids may also be washed in in the basket and dried to a very low moisture content. Removal of solids must be done for each batch either manually or with an automated discharge scraper system.
2) Solid Basket Centrifuges operate as a simple decanter system. Feed material is dumped into the rotating basket where solids are collected in the rotating basket by accelerated sedimentation from the rotating G force. Lighter liquid overflows the basket into the out chamber where it drains the centrifuge by gravity. These centrifuges have the ability to separate and capture some heavy liquid in the basket along with solids. Removal of solids must be done for each batch either manually or with an automated discharge system.
