Waste Paper Breaking Up and Wiping Off Impurity Equipment
If you are running a paper mill or planning a new setup, the stock preparation section decides your quality, downtime, and cost per ton. Micro Star Machines supplies waste paper breaking up and impurity removal equipment in Pakistan, designed to process mixed waste paper efficiently and protect downstream machines from damage.
Overview
Most commonly used machines in a waste paper recycling line, including hydra pulpers, drum screens, fibre separators, and impurity separators.
We support buyers across Pakistan with machine selection guidance, layout support, installation supervision, commissioning, operator training, and spare parts planning.
Where This Equipment Fits in the Line
A typical waste paper stock preparation flow looks like this:
- Pulping — breaking up waste paper
- Coarse Screening — remove big/heavy impurities early
- Separation — remove rope, plastic, light/heavy contaminants
- Fine Screening / Pressure Screening — improve pulp cleanliness
- Clean Pulp Feed — to paper machine
Note: The best configuration depends on your waste paper mix, target GSM, and capacity (TPD). Share your requirements and we'll recommend the right line.
Equipment Portfolio
D Type Hydra Pulper
The D Type Hydra Pulper is used to break waste paper into pulp while helping remove large contaminants early. Compared to basic pulper designs, the D-type vat and rotor arrangement improves fibre contact and supports faster pulping (depending on furnish and setup).
- Faster wetting and breakup of waste paper (configuration dependent)
- Better handling of mixed waste paper with higher contamination levels
- Helps reduce downstream screening load when paired with a drum screen
- Supports stable mill operation and fewer blockages
Best For: Kraft / test liner / fluting production, Mills using mixed waste paper and OCC
Ragger / Twisted Rope Removal
A ragger system removes stringy contaminants that can cause major downtime, including plastic sacks and film, ropes and twine, wires and wrapping materials. Adding a ragger improves pulper cleanliness and protects screens and pumps downstream.
Grab (Heavy Trash Removal)
A grab system is used to remove large and heavy impurities safely and regularly from the pulper area. It helps reduce metal pieces, stones and glass, heavy plastic lumps, and large contaminants that may damage the rotor and screens.
STY Series Drum Screen
The STY drum screen is installed after the pulper for rough screening. It removes big and heavy impurities coming out of pulping before they break into smaller pieces.
- Reduces load on fine screening equipment
- Helps protect pumps, cleaners, and pressure screens
- Improves pulp cleanliness early in the process
Best For: Waste paper lines using mixed raw material, Plants aiming for stable paper machine operation
FFDZ Duplex Fibre Separator
The FFDZ duplex fibre separator combines two important functions: further breaking/loosening of stock and pressure screening to improve cleanliness.
- Compact structure (useful when space is limited)
- Multi-function unit for higher and mid-grade paper lines
- Helps reduce impurity carryover into later stages
FDZ Series Single Fibres Separator
The FDZ fibre separator is used to remove impurities by separating fibres from contaminants. It supports secondary loosening (relieving), light impurity separation, and removal of heavy rough waste materials.
When It's Useful: When waste paper quality is inconsistent, When you want to reduce extra pretreatment steps, When mills need higher pulper productivity and cleaner pulp
FXDZ Single Effect Fibre Separator
The FXDZ single effect fibre separator is designed to further loosen stock and separate coarse impurities. It can be used in the main flow or on rough-screen tailings.
- Prevents impurities from breaking up completely
- Reduces the burden on downstream screens
- Supports stable operation when processing mixed waste paper
GGZ Series Drum Pulper
A GGZ drum pulper is suitable for continuous breakup and rough screening. It can process various scrap papers with minimal selection and can be configured for de-inking processes depending on your requirement.
- Continuous pulping + coarse separation
- Lower chance of shredding plastics into small pieces
- Helps remove plastics and fabrics more effectively in certain furnishes
GCSZ Series Vertical Super High-Density Hydra Pulper
The GCSZ high-density hydra pulper is designed for higher consistency pulping and stronger fibre rubbing action. It is often chosen for wet-strength papers (configuration dependent) and high-consistency pulping where stronger fibre-to-fibre friction is needed.
- Better fibre rubbing for difficult furnishes
- Strong structure for demanding operating conditions
- Useful for certain de-inking and special furnish cases
JGSZ Series Energy Conservation Hydra Pulper
The JGSZ energy-saving hydra pulper is designed to reduce energy usage while maintaining stable pulping performance.
- Lower installed power requirement (model dependent)
- Designed for easier maintenance access
- Useful where energy cost and operating efficiency are key
GSZ Series Vertical High-Density Hydra Pulper
The GSZ high-density hydra pulper supports high-consistency pulping and is used in stock preparation lines where the mill needs stronger fibre friction and stable pulping.
Common Uses: De-inking lines (depending on configuration), Mixed waste paper pulping with high consistency targets
2WSZ Series Double Vortexes Hydra Pulper
The 2WSZ double vortex hydra pulper uses a dual-vortex principle to accelerate hydration and pulping.
- Efficient pulping action (model dependent)
- Designed for reliable operation and simpler handling
- Suitable for mills aiming to reduce operating cost per ton
FZZ Series Impurity Separator
The FZZ impurity separator separates light and heavy contaminants and supports additional pulping/loosening as part of the cleaning process.
- Helps simplify the waste paper processing flow
- Supports continuous working and stable operation
- Reduces energy waste caused by repeated handling
WSZ Series Horizontal Type Hydra Pulper
A horizontal configuration hydra pulper designed for efficient waste paper processing and stock preparation applications.
Which Machine Should You Choose?
Here's a simple selection guide based on your requirements:
| Application / Requirement | Recommended Equipment |
|---|---|
| High contamination mixed waste paper | D Type Pulper + ragger + drum screen + fibre separator |
| Need early coarse separation | Drum screen after pulper |
| Need compact multi-function unit | FFDZ duplex fibre separator |
| Need extra impurity control before fine screens | FDZ / FXDZ separators |
| Continuous pulping preference | GGZ drum pulper |
| High consistency / difficult furnish | GCSZ / GSZ high-density pulpers |
Custom Configuration: If you share your paper grade and waste paper mix, we will recommend the correct flow and machine sizing.
