Under normal circumstances, the spiral discharge decanter centrifuge can maintain a stable running state for a long time, the washing effect is outstanding, the processing capacity is large, and the economic efficiency is high. The machine can automatically feed, wash, dewater, and discharge the suspension at full speed, which is an efficient separation device for current solid-liquid separation.
The spiral discharge decanter centrifuge is mainly composed of components such as a drum, a screw and a differential. In the process of processing the suspension, the rotating drum at high speed generates a strong centrifugal force to settle the solid phase particles larger than the liquid phase density to the inner wall of the drum. Due to the different rotation speeds of the screw and the drum, there is relative motion between the two. The relative movement of the spiral and the drum pushes the solid phase deposited on the inner wall of the drum toward the outlet of the small end of the drum, and the separated supernatant is discharged from the other end of the centrifuge.
Based on the above separation characteristics, the current spiral discharge decanter centrifuge is widely used in solid-liquid separation in chemical, pharmaceutical, food, metallurgy, mining and other industries. Separating the solid phase of the suspension in a linear or crystalline solid particle of 10%-80% solid phase particle diameter in the range of 0.05-5 mm, such as citric acid, gulonic acid, salt, ammonium sulfate, urea, and the like.
