Overview

The DDR (Double Disc Refiner) for cow dung pulp processing by QGI is a highly efficient refining machine designed to convert processed cow dung fibers into a uniform and well-refined pulp suitable for applications such as cow dung paper, eco-friendly boards, molded products, and cow dung paint production. The machine operates with two precision-engineered refining discs—one rotating and one stationary—which create controlled mechanical action to fibrillate and refine the fibers. This refining process improves fiber bonding strength, pulp consistency, and overall product quality.

The DDR Refiner is manufactured with heavy-duty cast iron or stainless steel construction to ensure durability, corrosion resistance, and long service life in continuous industrial operations. It is equipped with a powerful electric motor, robust shaft assembly, and precision-balanced refining plates that allow efficient fiber treatment while maintaining optimal energy consumption. The adjustable disc clearance mechanism enables precise control over refining intensity, allowing operators to achieve the desired pulp freeness and fiber characteristics for different end products.

This machine is widely used in cow dung paper manufacturing plants, eco-product processing units, and biomass recycling industries where consistent fiber refining is essential. The DDR Refiner by QGI is designed following international industrial standards, ensuring reliable performance, high productivity, and easy maintenance. With its advanced engineering and robust construction, it plays a crucial role in improving pulp quality and supporting sustainable manufacturing using cow dung as a renewable raw material.
