650 Type Decanter Centrifuge for Large-Capacity Separation

Decanter Centrifuge Product Introduction

The 650 Type Decanter Centrifuge for Large-Capacity Separation is engineered for continuous solid-liquid separation in high-throughput industrial processes. With a large bowl diameter and robust mechanical design, it delivers stable performance under heavy-duty operating conditions, enabling efficient processing of large volumes of slurry and suspension.

This decanter centrifuge is suitable for applications requiring high processing capacity, continuous operation, and reliable separation efficiency. It is widely used in large-scale industrial separation, material recovery, and production processes where throughput and operational stability are critical.

Working Principle

The slurry is continuously fed into the rotating bowl through the inlet pipe. Under high centrifugal force, solids are forced to the bowl wall while clarified liquid flows toward the liquid discharge.

The internal scroll conveyor, rotating at a slightly different speed from the bowl, continuously transports the separated solids to the conical end for discharge.
Liquid exits through adjustable weirs, allowing operators to fine-tune separation performance according to material properties.

This continuous process ensures stable separation efficiency, low manual intervention, and high processing consistency.

Key Advantages of the 650 Decanter Centrifuge

Large Processing Capacity
Designed for 20–80 m³/h throughput, ideal for medium-to-large scale continuous separation processes.

High Separation Efficiency
Up to 2100×g centrifugal force enables effective separation of fine solids and improves cake dryness.

Robust Mechanical Design
Heavy-duty bearings, reinforced bowl, and precision dynamic balancing ensure stable long-term operation.

Wear-Resistant Construction
Scroll flights can be protected with tungsten carbide coating or wear tiles, extending service life in abrasive applications.

Flexible Material Options
Wetted parts available in SS304, SS316L, or Duplex 2205, suitable for corrosive or chemically aggressive media.

Fully Automatic Control
PLC + HMI with variable frequency drives (VFD) allows precise adjustment of bowl speed and differential speed.

Typical Applications

• Municipal sludge dewatering
• Industrial wastewater clarification
• Oil sludge & drilling mud separation
• Mining slurry and tailings thickening
• Chemical process separation
• Food & beverage by-product recovery

The 650 model is especially recommended where high flow rate, continuous operation, and mechanical reliability are required.

Frequently Asked Questions

Q1: Is the 650 decanter centrifuge suitable for high-solids sludge?
Yes. With proper motor sizing and scroll protection, it is suitable for medium to high solids applications.

Q2: What does 2100×g mean in practice?
Higher G-force improves separation efficiency, especially for fine particles and difficult-to-separate materials.

Q3: How do I choose the motor power?
55 kW is standard; 75–90 kW is recommended for higher density or abrasive slurries.

Q4: Can the machine handle corrosive materials?
Yes. SS316L and Duplex 2205 options are available for corrosive environments.

Q5: Is customization available?
Yes. Material, wear protection, control system, and electrical configuration can be customized.
