Paper Mill Solutions

Yes-Zejiang is a manufacturer. We design and manufacture stock prep equipment, pulpers, headboxes, rolls, dryer cylinders and spare parts internally, and use this in-house capability to deliver complete turnkey paper mill projects. To verify the manufacturing status of any supplier from China, cross-check the company registration number against the National Enterprise Credit database and review the stated business scope; a manufacturer will have “production” as a listed activity, while a trader won’t. Any prospective buyer is encouraged to do so.

There’s no honest single number. A turnkey paper mill project cost depends on grade, capacity, machine width, integration level and country of destination, and a mini paper mill project is on a totally different magnitude from a 300 TPD kraft line. We don’t have a sticker price or a generic turnkey paper mill project report, because both more often obscure than illuminate. Instead, we deliver a detailed cost breakdown against your specifications, with the capital-cost structure, operating cost drivers and engineering assumptions appended, so your procurement team can back the number internally, instead of being surprised by the installation and spares cost after signing the purchase order.

From pulp to reel, that includes stock preparation and approach flow, the headbox, forming section (fourdrinier or crescent former), press section, dryer section with dryer cylinders or yankee dryer, size press, calender, pope reel and winder – plus the pulping line, utilities and boiler interface, electrical and instrumentation, and effluent treatment. turnkey means a single party takes ownership of the engineering that makes those segments come together, so the line hits its rated production capacity at commissioning.

We go through the whole spectrum of phases – contract and specification freeze, detail engineering, manufacture, buyer-witnessed factory acceptance test, shipping, civil interface readiness, mechanical erection, commissioning and performance trial run to acceptance. We specify a calendar duration, rather than a fixed number of months, per project because the true duration depends on the width of the machine, the grade, your civil readiness and the travel distance. If anyone quoted a fixed month duration “sight-unseen”, it was a marketing effort, not scheduling.

Yes – we’ve complete rebuild programs for press sections, dryer sections, and forming sections; new headboxes; shoe-press retrofits; control system upgrades and grade change projects (including recycled linerboard). The largest effect of a press section modernization comes from improving the dewatering performance, where even a 1% increase in solids enables 3-5% speed increases or an equal steam saving. At Zejiang, we’ll also tell you when it doesn’t make sense to modernize – if your frame, spare parts, or grade slate puts an unachievable ceiling on a modernization program, we’ll quote you for a new machine instead.

Yes – complete lines for waste paper recycling: pulping, coarse screening, fine screening, cleaning, de-inking and flotation for cultural papers. Waste is then processed into testliner and fluting for packaging applications (old corrugated, or OCC), or to duplex, newsprint, or other paperboard (mixed paper and recovered paper). Recycling old corrugated (OCC) to produce recycled linerboard has been established process technology (given appropriate process engineering), and we design the stock prep lines required to implement that process.

This includes the complete “risk transfer stack”: buyer witnessed factory acceptance testing (FAT) prior to shipping, independent pre-shipment inspections by a third party of your choice (SGS, BV, TV or Intertek), staged payments based on actual commissioning performance, and a written contract guarantee on rated production and grade. Each of these actions moves a risk off your plate and doesn’t require you to rely on the customer testimonials of our previous clients.

kraft, testliner and corrugated for packaging, duplex and white-top board, tissue on crescent-former lines with a Yankee dryer, cultural, writing-and-printing and newsprint, and specialty grades on engineered configurations. The grade is what drives the wet-end and the dryer configuration. That’s why grade and target capacity are the two initial questions we ask before providing a quote.
