Product Description:
Thickener is a type of solid-liquid separation equipment by gravitational sedimentation. The tapered bottom of thickener is a cylinder groove, consisted of concrete, wood or metal plates. Thickener can settle and concentrate the slurry solid density from 10~20% to 45~55% under the function of gravitation via the thickener rake. The thicken slurry is discharged from the bottom of thickener.
The Thickener Equipment is equipped with advanced features that make it easy to operate and maintain. The thickener equips a slow-moving rake that helps to promote settling of solids, which leads to improved separation efficiency.
The Thickener Equipment is an excellent investment for any industry that requires efficient solid-liquid separation.

Technical Process:
- During the thickening process, particles suspended in slurry is settled under the gravity force. At the settlement moment, the particles sink at acceleration by gravity function. After that, due to the water resistant, the acceleration of particle reduced, till the resistant force is same with particle gravity. Then the gravity keeps a constant settlement rate, which is called the final settling velocity.
- If the density of thicken slurry is small, it can ignore the collision and interreference between particles during settlement process. We call this free settling.
- If the density of thicken slurry is big, the mechanical resistant between particles during settlement process will be big. We call this interreference settling.
- The settling speed of free settling is fast than interreference one.
- During the continuous thickening equipment, the settlement and concentration can be divided into clarifying section, settling section, pressing section and squeezing section.
- If the feeding quantity is equal to drainage quantity, then every section can be fixed on a certain level and kept a dynamic balancing status. Every section looks static and remains unchangeable, which is difficult to achieve in operation conditions.
- Due to the difference between feeding and drainage, the dynamic balancing status is destroyed, the height of sections changed. To ensure the thickening process operating smoothly, the height of clarifying section: ≥ 0.2~0.3m, height of settling section: ≥ 0.3~0.5m.
