The bowl is driven at speeds of around 15,000 rpm (250 Hz) and the centrifugal force generated exceeds 130,000N. Disc bowl The conical discs in a disc bowl centrifuge split the liquid flow into a number of very thin layers, which greatly increases the separating efficiency. Disc bowl centrifuges are used for separating liquids and fine solids, and for solids classification.
Jul 05, 2016· Since the late 1980s, screen bowl centrifuge technology has been widely applied in coal preparation for recovery and dewatering of fine and ultrafine coal. Screen bowls are efficient and cost effective and, to a large extent, have replaced vacuum filters for recovery of these size fractions.

Flottweg Differential Speed. There is a differential speed between the decanter bowl and the decanter scroll (created by the gear unit). This is required in order to transport the solid particles that collect on the bowl inner diameter using the decanter scroll. As a result, the differential speed determines how long the solid material remains in the bowl.
A decanter centrifuge separates solids from one or two liquid phases in one single continuous process. This is done using centrifugal forces that can be well beyond 3000 times greater than gravity. When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phase forms a concentric inner layer.

This reduction in sludge retention time causes the cake dryness to
Casein curd was dewatered in a pilotscale screenbowl (basket) centrifuge (Conturbex model H250, Siebtechnik, Germany) at a flow rate of 3500 litres/h and temp. ranging from 34 to 40°C. Moisture content varied from 56 to 51% (wet basis) with increase in feed temp., and the dewatered curd was, in general, more friable and dried more readily than that dewatered by decanter (horizontal solidbowl...
Continuous filtering centrifuges, with the possible exception of the screen bowl design, prefer thick feed slurry (typically 50% by weight). There are two reasons for this: continuous filtering centrifuges may be limited by the amount of liquid to be centrifuged.
