Apparatus for separating liquids, such as oils from solids, such as drill cuttings, comprises a decanter-type centrifuge. In example implementations the centrifuge has a bowl angle of four degrees or less and a low fluid depth of two inches or less. A material conveyor such as an auger is provided to carry material having a relatively high initial solids content, such as 50% or more into the centrifuge. The apparatus may comprise heaters to heat the material. In example implementations the decanter-type centrifuge processes solids from a main centrifuge and/or a shale shaker.
