Kernel and granular separation
Used for the separation of any kind of kernel and granular product of almost identical size but with different weights. Utilized when the limits of air-aspiration systems and screening are reached. Gravity separators are an additional piece of equipment for separating more accurately according to specific weight.

A review of gas-liquid separation technologies: Separation …
Gravity separators based on the gravity settling principle can generally be divided into horizontal and vertical types, as shown in Fig. 2. The primary separation section contains different inlet structures, and the most common ones are the cyclone and the guide plate (Schoepentoeter) designed by Shell (Letzel, 2006). Some vertical …
Gravity Separation/Separators | Udemy
Here is some information for your interest: Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common ...
Gravity Separator Fundamentals and Design
Vertical gravity separation Vertical separation is the simplest case of gravity separation because all the motion occurs in a single plane, vertical. In addition, the vapor flow area and corresponding vapor velocity in a vertical vessel is unaffected by liquid level. Figure 3 shows a schematic of a vertical liquid-refrigerant separator.
