Both conical plate centrifuge and tubular bowl centrifuge can be used for liquid/liquid and solid/liquid separation. However, the advantage of conical plate centrifuge over tubular bowl centrifuge is that solid discharge is possible in conical plate but recovery of solids in tubular bowl is difficult and there is limited solid capacity.

A centrifuge is a device that uses centrifugal force to subject a specimen to a specified constant force - for example, to separate various components of a fluid. This is achieved by spinning the fluid at high speed within a container, thereby separating fluids of different densities (e.g. cream from milk) or liquids from solids.
A laboratory centrifuge is a piece of laboratory equipment, driven by a motor, which spins liquid samples at high speed. There are various types of centrifuges, depending on the size and the sample capacity.
Thus, conical-cylindrical bowl design is the most widely used in the industry today. A typical conical-cylindrical solid bowl centrifuge design contains a rotating bowl unit connected to a conveyor with a gear system. The gear system allows the rotating bowl and the conveyor to rotate at different speeds but in the same direction.
The P1 centrifuge uses an aluminum rotor, and the P2 centrifuge uses a maraging steel rotor, [3] which is stronger, spins faster, and enriches more uranium per machine than the P1. In Pakistan, the Zippe-type centrifuge had a local designation and was known as Centrifuge Khan (after Abdul Qadeer Khan).: 151 [10]
The decanter centrifuge cannot separate biological solids with very small density differences, such as cells and viruses. [5] A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge. The machine can be very noisy and can cause vibration.
The material variations for constructing and the design of main components of centrifuge such as the screen plate, helical screw and basket could actually improve the longer life term of the machine. Another important factor is the conical basket size and its angle within the centrifuge.
