centrifugal common clay ball
A centrifuge is a device for separating two or more substances from each other by using centrifugal force. Centrifugal force is the tendency of an object traveling around a central point to continue in a linear motion and fly away from that central point.
Centrifugation can be used to separate substances from each other becausematerials with different masses experience different centrifugal forces when traveling at the same velocityand at the same distance from the common center. For example, if two balls of different mass are attached to strings and swung around a common point at the same velocity, the ball with the greater mass will experience a greater centrifugal force. If the two strings are cut simultaneously, the heavier ball will tend to fly farther from the common center than will the lighter ball.
Centrifuges can be considered devices for increasing the effects of the earth's gravitational pull. For example, if a spoonful of clay is mixed vigorously with a cup of water and then allowed to sit for a period of time, the clay will eventually settle out because it experiences a greater gravitational pull than does the water. If the same clay-water mixture is centrifuged, however, the separation will take place much more quickly.

Centrifuges can be sub-divided into two major categories, stationary devices and rotating devices. Both types of centrifuge work on a common principle, however. A collection of particles of different mass is set into motion around a common center. The faster these particles move, the greater will be the difference with which they tend to escape from their common center, and the more easily they wi…
Another type of centrifuge is one in which the fluid to be separated is introduced into a container, and the container is then set into rapid rotational motion. Most beginning chemistry students are familiar with this instrument. It is commonly used as a substitute for filtration in the separation of a solid precipitate from the liquid in which it is suspended. In this kind of machine, hollow tube…
The basic centrifuge design described above can be adapted for use in many different settings. Industrial centrifuges, for example, tend to be quite large, ranging in size from 4 in to 4 ft (10 cm to 1.2 m) in diameter, with rotational velocities from 1,000 to 15,000 revolutions per minute. They can be designed so as to remove separated portions continuously, all at once after the machine has been…
Centrifuge studies have been very important in the development of manned space flight programs. Human volunteers are placed into very large centrifuges and then spun at high velocities. Inside the centrifuge, humans feel high gravitational velocities that correspond to high gravitational forces ("g forces") that occur during the launch of space vehicles. Such experiments help space s…

You mentioned only two types of centrifuges .Where are the others
