D-Hydrapulper is a type of equipment used in the pulp and paper industry for the pulping process. It is a machine that uses mechanical energy to break down wood chips or recycled paper into fibers and separates them from contaminants such as glue, ink, and other impurities.

The process of pulping involves adding water to the wood chips or recycled paper in the D-Hydrapulper, which creates a slurry.

D-Hydrapulpers are commonly used in the production of various types of paper, including newsprint, writing paper, and cardboard. They are also used in the production of tissue paper and other paper products that require a high-quality pulp.
