Firstly, decanter centrifuge is widely used in oil field, ship, waste water treatment, it is kind of equipment to processing waste fluid, and it is becoming more and more widely used for protecting the environment. We know that wherever water is used, solids will be mixing with water, and for protect the environment, we need to find a way to process the slurry, so the decanter centrifuge is one of machinery for processing the waste fluid

How does the decanter centrifuge work?

Popular explanation on working principle of decanter centrifuge, we can do a game, take out a sheet of paper, draw a circle and points out the location of the center of the circle and draw a radius. We assume that the radius and circular intersection point there is an object, so this is a very simple centrifuge longitudinal view. we know that there are small particles in the suspending liquid, particles in the decanter centrifuge bowl will sink because of gravity, the heavier the particle, the faster sinking. Sinking speed is related to the size, shape and density of particles. In addition, the material was accompanied by a diffusion phenomenon in the decanter centrifuge, the smaller the particle diffusion is more serious, the particle is colloid or half colloidal state, it is impossible to use gravity to separate the particles by decanter centrifuge force. The slower because the smaller the particle sedimentation, and diffusion phenomenon is more serious in the drilling waste. So a strong decanter centrifuge force is required to overcome the diffusion to produce subsidence movement. Decanter centrifuge is to use strong centrifuge force with a high-speed rotation, to speed up the settlement of particles in the liquid

So we can say the theory sample like this, the decanter centrifuge is using high G force to separate the particles in the liquid, because the particles and water is different density. While the decanter centrifuge can not separate too small particles because of particle is colloid already.
