As a manufacturer with over 25 years of experience (since 1998), Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our Rigorous Quality Control Perforated Dewatering Plate specifically designed for coal washing applications. Our plates undergo strict inspection at every production stage to ensure defect-free performance, and we offer a free replacement for any defects — a testament to our confidence in product quality. With an annual export value of US$5-10 million, we serve global markets including North America, South America, and Europe, providing reliable dewatering solutions that enhance your coal processing efficiency.
Our perforated dewatering plates are engineered to separate water from coal slurry effectively, reducing moisture content and improving coal quality. The precision-punched holes create a uniform dewatering surface, while the robust construction withstands heavy use and abrasive conditions. Whether you need standard sizes or custom dimensions, we offer flexible options to match your existing equipment. Below, we detail the key features that set our product apart.
Key Features & Technical Specifications
- Superior Material Selection: Made from high-quality stainless steel or carbon steel, our plates offer excellent corrosion resistance and strength for long service life.
- Precision Perforation: All holes are uniformly punched with tight tolerances, ensuring consistent dewatering performance and minimal clogging.
- High Open Area Ratio: With open areas ranging from 40% to 60%, our plates maximize water drainage while retaining solid particles.
- Rigid Structure: Thick plate material (3-12mm) and reinforced edges prevent deformation under high load and vibration.
