From Factory Tour to Long-Term Deal: Why a Belgian Customer Chose DAGYEE Decanter Centrifuge
A Belgian Customer Walked Through Our Factory. Here’s What They Saw.
Introduction
We build decanter centrifuges for this industry. All of them come with CE certification.
Recently, a major Belgian wood chips company came to visit us. They are well known in the European market. They wanted to see our CE-certified decanter centrifuges for themselves — the quality, the performance, how we make them. After the visit, they felt confident in what we do.
This article walks you through that inspection. You will also learn why our CE-certified decanter centrifuges stand out in the global wood processing industry.
Why Wood Chips Processing Needs Good Separation
If you just dump them, you cause pollution and throw away recoverable resources.
Our CE-certified decanter centrifuge meets EU safety, health, and environmental standards. It pulls solid wood fiber out of the liquid quickly. The fiber goes back into production. The treated water meets EU discharge rules. That means better business and less harm to the environment.
Key Benefits of CE-Certified Decanter Centrifuge
| Benefit | How It Helps |
|---|---|
| Fiber Recovery | Reclaims valuable wood fiber from wastewater |
| EU Compliance | Treated water meets strict EU discharge standards |
| Cost Reduction | Lowers raw material and waste disposal costs |
| Environmental Protection | Reduces pollution from wood processing waste |
Who Was the Customer
The company had been searching for a high-performance, CE-compliant decanter centrifuge to replace their old unit. They looked at several manufacturers. They chose us because we offer custom designs, CE-certified quality, and solid after-sales support. Then they decided to visit our factory for a final check.
We took the visit seriously. We got the production line ready. We tuned the demo machine. We gathered quality inspection documents and CE certificates. We planned the whole reception. We wanted them to see exactly what we can do.
The Factory Inspection: Seeing CE-Certified Quality Up Close
Our team welcomed the Belgian customer warmly. We started with a tour of our 65,000-square-meter production base. It includes centrifugal casting workshops, precision machining centers, assembly lines, dynamic balancing test workshops, and quality inspection centers. All these facilities run under a quality management system that meets CE requirements.
The customer watched every production step closely. They asked a lot of questions about raw materials, processing technology, and quality control — especially how each part meets CE standards. Our engineers answered everything and showed them test reports and certification documents.
Raw Materials: What We Use
First stop was the material warehouse. We showed them what we work with: 304 stainless steel, duplex stainless steel (grades 1.4418, 1.4462, 1.4410), and wear-resistant materials like tungsten carbide and ceramics. All of these meet CE material safety and corrosion resistance standards.
We explained that every batch comes with a heat number-tracked certificate. That is a key requirement for CE certification. This traceability ensures the materials can handle the corrosive and abrasive conditions of wood pulp wastewater over the long run. They also meet EU environmental and safety standards.
The customer reviewed the material certificates and CE test reports. They even took samples on site. They were satisfied with both the quality and compliance of our raw materials.
Centrifugal Casting: One Piece, No Welds
Next, we went to the centrifugal casting workshop. We use seamless one-piece centrifugal casting to make decanter centrifuge bowls. This removes weld seams, which improves mechanical strength and service life. That is a critical CE safety requirement.
The customer pointed out that traditional welded bowls often crack after running at high speed for a long time. That does not meet European safety standards. Our one-piece bowls avoid that problem entirely.
Precision Machining: Accuracy Down to ±0.01mm
At the precision machining center, key components — the screw conveyor, drum, and drive unit — are machined using CNC lathes and machining centers. We hold accuracy to ±0.01mm. That ensures tight component fit and stable high-speed operation. This is another core CE requirement.
The customer checked surface finish and dimensional accuracy with professional tools. They confirmed that all dimensions met design specifications and CE standards.
Dynamic Balancing: Low Vibration, High Safety
In the dynamic balancing test workshop, the customer watched the test on our CE-certified sample machine. Every decanter centrifuge we ship goes through strict dynamic balancing tests. We meet ISO 21940-11 G2.5 or G6.3 standards — fully compliant with CE safety requirements.
The test data showed vibration amplitude far below EU limits. That proved the excellent safety and stability of our products.
Performance Test: Real Results
The highlight of the inspection was the live performance test. We used wood chips sludge samples that matched the customer's actual production conditions.
Our decanter centrifuge processed 50 to 100 tons of sludge per hour. The separated wood fiber had moisture content as low as 60%. The clarified liquid met EU standards for recycling or discharge.
Compared to their old equipment, our product had higher capacity, better separation, and lower energy consumption. It fully met CE energy-saving and environmental requirements. The customer was impressed. They said the results exceeded their expectations.
Performance Test Results
| Metric | Result | CE Requirement |
|---|---|---|
| Processing Capacity | 50-100 tons/hour | Meets CE efficiency standards |
| Solid Moisture Content | ≤ 60% | Compliant with EU disposal rules |
| Separation Efficiency | ≥ 98% | Meets CE environmental standards |
| Energy Savings | 20-30% lower than traditional equipment | Meets CE energy efficiency |
Quality Control and CE Paperwork
The customer also reviewed our quality control system and CE documents. That included ISO 9001, CE (EU Directive 2014/34/EU), and EAC certificates, along with production inspection records.
Our factory follows 6S management. We have 12 full-time quality inspectors. Every product is checked against CE standards. Non-conforming products are strictly isolated and disposed of. The customer highly recognized our rigorous quality control. They said this is essential for entering the European market.
Product Advantages: CE-Certified Decanter Centrifuge for Wood Chips Processing
It has a high-speed drum, a differential screw conveyor, a drive unit, and a Siemens PLC control system. It uses centrifugal force 1,000 to 4,000 times gravity. It feeds, separates, and discharges continuously. It works well for wood pulp washing, sawdust sludge treatment, and fiber recovery.
We offer over 100 models. Key specs — bowl diameter (250–1000mm), length-diameter ratio, motor power, and torque — can be customized. The Siemens PLC touchscreen enables automatic operation and real-time monitoring. All electrical components are CE-certified for European market safety.
