Before setting up a paper mill, buyers must understand that modern production consists of two core steps:
- Stock Preparation: Raw materials such as waste paper, virgin wood pulp, rice straw, or bagasse are filtered to remove impurities, deslagged, and refined into stock pulp graded into three uniformity levels.
- Forming and Drying: The prepared pulp is formed, dewatered, and dried into large finished jumbo rolls.
Selecting matching paper pulp equipment reduces waste residue while boosting paper sheet tensile strength. Furthermore, standard paper production uses 15 tons of water per ton of paper, but water-saving recycling equipment drops that figure down to 3 tons per ton.
Tip: Look beyond the main paper machine price tag! If local water fees or environmental rules are strict, adding a water-recycling loop pays for itself rapidly through low operating costs.
How to Choose Among the 3 Main Types of Paper Making Machine?
Except for specialty paper equipment, the industrial paper market relies on three primary categories:
- Kraft Liner, Test Liner & Fluting Paper Machine: Produces durable packaging sheets and corrugated boxes with weights ranging from 80 to 250 gsm.
- Tissue Paper Making Machine: Makes jumbo rolls for toilet tissue, napkin paper, and facial tissue at 11 to 35 gsm for conversion and retail sale.
- Writing & Printing Paper Machine: Delivers high-flatness paper for A4 copy paper and notebook printing at 70 gsm, 80 gsm, and 90 gsm.

| 3 Main Paper Machine Categories |
+--------------------------+-----------------------+------------------------------+
| Machine Type | Output Paper Grades | Basis Weight (GSM) |
+--------------------------+-----------------------+------------------------------+
| Kraft Paper Machine | Kraft, Liner, Fluting | 80 - 250 gsm |
| Tissue Paper Machine | Toilet Roll, Napkin | 11 - 35 gsm |
| Writing Paper Machine | A4 Copy, Printing | 70, 80, 90 gsm (De-inking) |
+--------------------------+-----------------------+------------------------------+
Pro Tip: If you plan to make A4 copy paper from recycled stock, make sure to add a de-inking system. Without it, the finished paper won’t meet office whiteness standards.
How to Mix Raw Materials: Waste Paper, Wood Pulp, and Straw?
Paper production permits flexible raw material ratios based on local availability:
- Waste Paper & Wood Pulp: High-grade waste paper can be used at 100%. Lower-grade waste paper works well in a 50% waste paper + 50% wood pulp blend.
- Crop Waste Fiber: Rice straw, wheat stalk, and sugarcane bagasse can all produce quality paper pulp.
- Material Yield Conversion Formulas:
- 3 tons of straw = 1 ton of pulp
- 2 tons of wood = 1 ton of pulp
- 1.2 tons of waste paper = 1 ton of pulp
- 1 ton of wood pulp = 0.95 to 1.28 tons of finished paper
Pro Tip: Straw fiber is short. If you use cheap local agricultural waste, blend in at least 30% wood pulp or waste paper pulp to maintain strong paper tensile strength.
Step-by-Step Production Process for Kraft Paper
Understanding the exact sequence of a kraft paper machine production line helps optimize workshop piping and layout design:
Raw Materials (Waste Paper) ➔ Pulper ➔ Vibrating Sieve ➔ Pulp Tank ➔ Pulp Pump ➔ Bleach Machine ➔ Refiner Machine ➔ Pulp Tank ➔ Pulp Pump ➔ Pressure Sieve ➔ Pulp Tank ➔ Pulp Pump ➔ Sand Removal Machine ➔ Net Box ➔ Cylinder/Wire Section ➔ Blanket ➔ Paper Making Machine ➔ Drying ➔ Roll Paper ➔ Jumbo Finished Paper
Once jumbo kraft rolls are produced, downstream converting equipment cuts and rewinds them to buyer specifications.
Pro Tip: Never skip the sand removal machine! Fine grit inside recycled pulp scratches dryer cylinders and forming wires quickly, causing expensive downtime.
Minimum Machine Capacity and Budget-Based Selection Tips
Many buyers start inquiries without a fixed daily target output. Instead of guessing numbers, work backward from your plant space or budget to find the ideal machine size.
- Minimum Start-up Capacities:
- Tissue machine: 5 TPD minimum (Small 787 models handle hundreds of kilos; standard 1092 and 1575 models start here).
- Kraft/Corrugated paper machine: 6 TPD minimum.
- Writing paper machine: 10 TPD minimum.
- Mainstream Models & Wire Types:
- Kraft paper machine: Recommended 50–150 TPD (up to 300 TPD max).
- Tissue paper machine: Recommended 5–10 TPD (below 50 TPD max).
- Wire structure selection: Under 20 TPD, choose cylinder wire or Fourdrinier wire; over 20 TPD, choose a crescent former paper machine.
Pro Tip: If your budget is tight and space is small, start with a 1092-model 5–10 TPD tissue line paired with a rewinder for fast ROI.
Frequently Asked Questions About Paper Making Machine Sizing
Space depends on daily output capacity. A 5–10 TPD tissue machine line needs a hall length of 35–45 meters and width of 6–8 meters for pulping, forming, and storage. A 50–150 TPD kraft paper line requires a hall length of 60–90+ meters.
Prices depend on net paper width (e.g., 787mm, 1092mm, 1575mm), daily output tonnage, and pulping automation levels. Sharing your target workshop layout or budget allows engineers to recommend high-ROI custom configurations right away.
