A disk-type centrifuge accelerates the separation of materials by utilizing a vertical stack of thin, cone-shaped disks. This design creates narrow spaces between adjacent cones, which significantly reduces the settling distance required for particles to reach a surface.1

By shortening this distance, the instrument increases the overall rate of separation. Once particles reach the inside surface of a cone, the heavier material slides down along it, a process similar to the function of a fixed-angle bottle centrifuge. These devices typically operate in a continuous flow, making them highly effective for purifying liquids with low concentrations of solids or immiscible components, such as in a cream separator or for the reclamation of fuel oil.1
