Categories of Used Stock Preparation Equipment and Machinery We Offer

Our inventory covers all key components for stock prep in the paper industry, allowing you to source everything from complete machines to critical replacement parts. Products that we offer under this category include:

Pulpers

These machines break down raw wood fibers or recycled paper into a pulp slurry, preparing it for further processing. High-quality used pulpers ensure smooth fiber separation and reduce contaminants.

Pulper Drives and Rotors

The pulper mechanical drive and rotor are essential for maximizing uptime and performance. Knowledge of high-quality surplus spare drives, rotors, or extraction chambers can be crucial to your company’s success.

Detrashers

Machines designed to remove unwanted contaminants, such as dirt, sand, and other heavy inorganic materials, from the pulp slurry.

Reject Sorters

Separate and remove non-fiber materials. Reject sorters help improve pulp quality by eliminating debris, plastics, and other contaminants.

Disk Refiners

These are critical in fiber treatment, refining pulp fibers to improve bonding strength and paper quality.

Defibrators

Critical for virgin fiber to mechanically separate and break down wood chips into individual fibers, producing uniform pulp for papermaking.

Deflakers

Further refining to break down clumped fibers or flakes, ensuring uniform slurry consistency for smooth paper formation.

Low Density Cleaners

Used to separate lightweight contaminants such as bark, plastics, and dirt from the pulp, enhancing purity.

High Density Cleaners

These machines remove heavy contaminants like sand and metal particles, protecting downstream equipment.

Pressure Screens

Pressure screens filter oversized particles and knots from the pulp slurry, preventing clogging and maintaining product quality.

Benefits of Buying Used Stock Preparation Equipment for Paper Manufacturing

  • Immediate Availability: Unlike new equipment with long lead times, used machines are often ready for delivery, minimizing production interruptions and expenses.
  • Match to Existing Equipment: Used machines match the existing equipment footprint and capabilities, resulting in significant cost savings.
  • Proven Durability: Many used machines have extensive operational histories and offer reliability comparable to new units.
  • Significant Cost Savings: Purchasing used equipment reduces upfront capital expenditures, allowing mills to invest in other critical areas.
  • Sustainability and Resource Efficiency: Extend equipment lifecycles and reduce waste, supporting environmental sustainability.
  • Flexible Scaling: Used equipment allows mills to expand or modify production capacity more flexibly and economically.

Application Areas of Stock Preparation Machines in the Paper Industry

  • Graphic and Printing Papers
  • Tissue and Towel Manufacturing
  • Specialty and Technical Papers
  • Packaging Papers
  • Recycled Fiber Processing

How to Select the Right Used Stock Preparation Equipment
