Product Description
Medium pulping machine also known as pulping machine 4m³ ,it is the core pulping equipment in the pulp and paper industry, designed for efficient pulping of pulp boards, waste books, cartons and other raw materials.
Its vertical structure combined with high-strength impeller and rotor system can achieve rapid fiber decomposition and ink separation under high concentration conditions, while protecting the integrity of light impurities for subsequent screening.
Core structure of medium pulping machine
- Tank: wear-resistant material, volume 4m³, optimized fluid dynamics design
- Impeller & rotor: bidirectional spiral blades, with both radial crushing and axial flipping functions
- Screen plate: customizable aperture to meet different pulp requirements
- Column: heavy-duty support structure to ensure operational stability
Working principle of medium pulping machine
The 4m³ high-concentration hydraulic pulper adopts a unique three-helix rotor design to achieve efficient disintegration of waste paper under high temperature and high concentration conditions.
The equipment drives the pulp to form a high-intensity circulating vortex through the rotation of the rotor, which promotes the fiber dissociation of waste paper raw materials under the synergistic effect of mechanical friction and chemical agents.
In this process, ink particles and pollutants are effectively stripped through the dual effects of inter-fiber friction and chemical agents, creating favorable conditions for subsequent flotation deinking and screening purification processes, and finally obtaining high-whiteness pulp products.
advantages of medium pulping machine
Adopting optimized fluid dynamics design to achieve large-volume production.
Innovative energy transfer mechanism, significantly reducing unit energy consumption.
Modular structure design, greatly improving maintenance convenience.
Intelligent control system ensures process stability.
It is particularly suitable for the production of high-quality recycled pulp that requires maintaining the characteristics of the original pulp, and its process efficiency has been verified by industrialization.
