Pulping Process (Chemical & Mechanical Pulping)
The pulping process, including chemical (kraft or sulfite) and mechanical pulping, involves transferring slurry mixtures of wood fibers and chemicals through various stages of digestion and washing. This process breaks down the wood to separate fibers and remove impurities. Centrifugal pumps, diaphragm pumps, and piston pumps are used to efficiently transport the slurry and chemicals, ensuring smooth flow throughout the stages and maintaining consistent processing.
