The Horizontal Decanter Screen Bowl Centrifuge, commonly known as the Screen Bowl Centrifuge, combines centrifugal sedimentation and filtration to efficiently dewater fine particles like 0.045-1mm flotation concentrates, tailings, and slimes. This continuous solid-liquid separation device surpasses pressure filters in processing capacity, residual moisture reduction, compact footprint, energy efficiency, and simplicity of operation.
Developed by HOT (Chengdu) Industries Co., Ltd., this centrifuge incorporates advanced international design principles and several innovative features. Engineered for coal washing plants that demand high workloads and extended operational periods in harsh environments, the DSBC series ensures reliable, long-lasting performance.
Working Process
The DSBC Series Horizontal Decanter Screen Bowl Centrifuge integrates several key stages to achieve efficient solid-liquid separation and dewatering of fine coal particles.
1. Mixing and Acceleration Stage: In the specially designed feed chamber, slime water is mixed and accelerated for optimal separation.
2. Clarification Stage: Under centrifugal force, particles quickly separate and settle, with clarified liquid discharged through the overflow weir.
3. Compression Stage: The spiral propeller pushes settled solids to the compression section, further compressing them and releasing interstitial water.
4. Filtration Stage: The solids advance to the screen filtration section, where they undergo further dewatering under centrifugal force.
5. Discharge Stage: The dewatered solids are expelled by the discharge scraper.
Key Features and Structures
The DSBC Horizontal Decanter Screen Bowl Centrifuge excels in dewatering ultra-fine coal slurry through centrifugal sedimentation and filtration technology. Key features include:
