Center Driving Thickener

1.Product Introduction

The center-driven thickener is a deep-layer distribution and agitation device driven by an electric motor or hydraulic motor via a central transmission mechanism, equipped with manual or automatic rake lifting functions. Its structure primarily includes a bridge frame, transmission device, flow stabilizing barrel (or central column), rake frame, and hydraulic station or electrical control system.

2.Application

Its applications are extensive, primarily covering the following fields:

• Mining and Metallurgy: In mineral processing plants, used to concentrate flotation, magnetic separation, or gravity separation concentrates or tailings slurry, providing high-concentration underflow for filtration.

• Coal Industry: In coal preparation plants, used to concentrate coal slurry for recovering fine coal particles and clarifying water for reuse.

• Chemical and Environmental Protection: In wastewater treatment and chemical production processes, used for settling and concentrating suspended solids.

3.Working Principle

The operating principle of the center-driven thickener is based on gravitational settling. Slurry enters the bottom of the thickening tank through a central feed pipe. Within the tank, solid particles slowly settle to the bottom under gravity, forming a thickened layer. A rotating rake frame (rake arms) mounted at the lower end of the drive shaft rotates slowly, gently scraping the settled solids (underflow) toward the discharge outlet at the tank center for removal. The clarified upper liquid (overflow) then spills over the overflow weir around the tank periphery. When the rake frame encounters excessive resistance, the lifting mechanism can automatically or manually raise the frame to prevent equipment damage.

4.Advantages

• Compact structure with high drive efficiency: Utilizes a central single-point drive with a direct transmission path, resulting in relatively low energy consumption. Particularly suitable for small to medium diameter thickening tanks.

• Stable and reliable operation: Deep-layer distribution and central agitation promote uniform sedimentation, enhancing thickening efficiency. The automatic rake lifting function effectively handles load variations and protects the equipment.

• ‌Easily Automated Control‌: When using hydraulic motor drive, fluid pressure replaces electric motor drive. Combined with components like pressure relays, this simplifies signal measurement and enhances interference resistance, facilitating automation (e.g., automatic rake lifting).‌

• ‌Wide Applicability‌: The comprehensive product range covers everything from laboratory-scale units to large industrial equipment, meeting diverse capacity and processing volume requirements.‌

• ‌Relatively Simple Maintenance‌: The centralized drive structure features a straightforward design with consolidated maintenance points, helping reduce long-term operational costs.‌
