Clarifier Centrifuges & Clarifier Separators for Sale

Buying and Selling Unused, Used and Reconditioned Clarifier Centrifuges

Clarifier centrifuges are critical elements within industrial separation processes, employing centrifugal force to achieve efficient liquid-solid separation. Phoenix offers a variety of clarifier centrifuges from some of the industries top brands including, but not limited to:

• Alfa Laval
• Sharples
• Westfalia
• Robatel

Operating Principles:

1. Feed Introduction: The unclarified liquid mixture, often referred to as a slurry, is introduced into the centrifuge's primary chamber – a cylindrical vessel designed for high-speed rotation.
2. Centrifugal Separation: As the chamber rotates at high velocity (typically measured in thousands of RPM), the centrifugal force generated acts upon the slurry. Heavier solid particles, due to their greater inertia, experience a higher outward radial force compared to the lighter liquid components. This differential force causes the solids to migrate radially outward, accumulating on the inner periphery of the chamber.
3. Liquid Clarification: Conversely, the clarified liquid, possessing a lower mass, experiences a lesser centrifugal force and migrates towards the central axis of the chamber.
4. Continuous Clarification: As the clarified liquid accumulates in the central zone, it exits the chamber via strategically positioned discharge ports. This continuous process allows for uninterrupted liquid clarification.
5. Solid Discharge: Once the solids reach a predetermined level within the chamber, a discharge mechanism is employed. This mechanism can be manual or automated, depending on the specific model and the characteristics of the solids (e.g., their consistency and flowability).

Applications:

Clarifier centrifuges or separators find application in a diverse range of industries due to their effectiveness in solid-liquid separation. Here are some prominent examples:

• Municipal Wastewater Treatment: Clarification of primary or secondary wastewater sludge is a crucial stage in municipal wastewater treatment facilities to separate solids for proper disposal and generate clarified effluent for further treatment.
• Coal Processing: Within coal-fired power plants, clarifier centrifuges are employed to remove particulate matter and enhance the efficiency of coal utilization by removing unwanted solids from coal waste slurries.
• Polymer Production: Various stages of polymer manufacturing necessitate clarification processes. Clarifier centrifuges play a significant role in removing impurities and achieving the desired product quality.
• Marine Applications: Onboard ships, clarifier centrifuges are utilized to purify fuel oil by separating contaminants and water, ensuring smooth engine operation and optimal fuel efficiency.

Considerations for Selection:

The selection of an appropriate clarifier centrifuge hinges on several critical factors, including:

• Feed Characteristics: The properties of the feed slurry, such as the size and concentration of solids, significantly influence the choice of centrifuge model and operating parameters.
• Desired Throughput: The required processing capacity (volume of liquid processed per unit time) is a crucial consideration for selecting a centrifuge with adequate capacity.
• Solid Discharge Requirements: The type of solid discharge mechanism (manual or automatic) should be chosen based on the solids' characteristics and operational needs.
