Best Performance Paper Pulping Machine
Wood chips, sawdust, bark, textiles, fabrics, and other small pieces serve as basic raw materials in paper pulping machine manufacturing. The bark and stems are burned to generate fuel that powers electric machines at factories.
The wood chips are first sorted according to their size. Pieces that are either too big or too small are removed and used in fuel-making. The sorted chips are washed and sent to the digester.
The wood chip content is approximately 50 percent water and 25 percent cellulose fiber. This cellulose fiber comprises the pulp, the main ingredient in paper manufacturing.
The leftover liquid material is called lignin, which functions as a glue holding fibers together. Removing this lignin separates fibers needed for the papermaking process.
In the paper pulping machine, digesters perform this separation. This process occurs in a large pressure cooker-like structure where wood chips are placed with white liquor. After sealing the vessel, steam is introduced. Increasing heat and pressure cause lignin to dissolve and wood chips to break down.
The resulting black liquor is burned in a recovery boiler, generating steam and electricity for the mill. This recycling process is environmentally friendly and cost-effective.
The remaining cellulose fiber is transferred to the bleaching station and undergoes the bleaching process where pulp is cleaned with bleach and water.
