Decanter Centrifuge

Equipment Introduction:

The decanter centrifuge is a solid-liquid separation equipment widely used in industries such as chemical, environmental protection, food, and pharmaceuticals. The core working principle is to achieve rapid separation of solid particles from liquid phase through centrifugal force generated by a high-speed rotating drum.

Working Principle:

The horizontal spiral centrifuge is mainly composed of components such as a rotary drum, a screw conveyor, a differential, and main and auxiliary motors. After the material is continuously introduced into the drum through the feeding pipe, heavy solid particles deposit on the inner wall of the drum under the action of centrifugal force, forming a sediment layer; The lighter liquid phase forms an inner liquid ring. There is a speed difference between the screw conveyor and the drum, which continuously pushes the solid particles to the cone end of the drum and discharges them, while the liquid phase is discharged through the overflow port, thus achieving continuous separation.

Technical features:

Continuous operation: It can achieve continuous operation of feeding, separation, washing, and unloading at full speed.

Strong adaptability: suitable for separating suspensions with solid particle size greater than 0.005mm and concentration range of 2-40%.

Good separation effect: The separation factor is determined by the radius and speed of the drum, and high speeds (usually above 3000 revolutions per minute) can improve the separation effect.

Automated control: Modern equipment commonly adopts automated programming control, supporting flexible adjustment of parameters such as differential speed and overflow plate diameter.

Application fields:

The decanter centrifuge is mainly used for:

Environmental protection field: sludge dewatering, sewage treatment (such as printing and dyeing sludge, blast furnace gas washing water sludge).

Chemical and Food: Chemical suspension separation, juice clarification, crude oil grading.

Pharmaceutical and petroleum: pharmaceutical intermediate separation, petrochemical three-phase separation.
