I. Introduction to the Decanter Centrifuge

The horizontal spiral discharge settling centrifuge operates on the principle of centrifugal settling, enabling continuous solid-liquid separation. The solid phase is discharged via the spiral, making it an efficient and continuous equipment suitable for various industries.

1. Wide application range and good adaptability. It can be used in pharmaceutical, chemical, light industry, food, papermaking, mining, and other sectors. It's ideal for suspensions with solid concentration less than 10% or volume concentration less than 50% after 24 hours. Suitable for particles ranging from 0.005 to 2 mm and a density difference of at least 0.05 g/cm³. Examples include calcium carbonate, polyvinyl chloride, lees, soybean dregs, paper pulp, vegetable oil, sludge, etc.

2. Continuous production, high capacity, low energy consumption, and high automation. Perfect for industrial lines.

3. Frequency conversion control allows for stepless speed regulation, ensuring optimal separation results.

4. Fully enclosed operation, no pollution or odor. Ideal for pipeline production environments.

5. Compact design, small footprint, easy installation, and maintenance. High wear resistance due to tungsten carbide coating on vulnerable parts.

6. All contact parts are made of corrosion-resistant stainless steel, polished to mirror finish.

Product structure: consists of a column-cone drum, screw discharge device, differential speed system, bearing seat, housing, main and auxiliary motor, and electrical system. The main motor drives the drum, while the auxiliary motor controls the planetary gear differential, allowing for a controlled differential speed between the drum and the spiral.

Working principle: the drum and the screw rotate at a certain differential speed. The material enters the feeding chamber, accelerates under centrifugal force, and forms a sediment layer on the drum wall. The spiral pushes the solid content toward the cone end, where it is discharged through the dry zone. The liquid overflows from the large end of the drum.

Decanter centrifuge is the best choice for first-step soy sauce separation because of its 40-50% water content and solid-liquid content. After decanter centrifuge separates the solid, the remaining soy sauce can be further processed by disc centrifuge.

With global water shortages and stricter environmental protection policies, the demand for sewage treatment continues to grow. Municipalities and industries must choose harmless solutions for sewage and sludge treatment. We ensure that our sludge treatment solutions are long-term and secure, and we also use high-tech equipment to recover valuable substances.

No matter the solution, the most economical and effective method is the core of sludge treatment. Choosing the right technical equipment and processing methods determines the economy of the dehydration system.

Considering storage, transportation, incineration, or landfill costs, increasing the solid content of dehydrated sludge is crucial for reducing treatment costs. To achieve the best processing results, optimizing the sludge dehydration process is essential to obtain higher dryness and smaller volume sludge.

The decanter centrifuge provided by Guangzhou Fuyi Company achieves high separation acceleration and optimal differential and torque adjustment for the best dehydration effect. Efficient dewatering reduces sludge volume significantly, lowering related treatment costs.
