The vacuum transfer roll is the core wet-end component of paper machines, responsible for paper web adsorption, vacuum dewatering and stable web transfer. It directly determines paper forming quality, dewatering efficiency and high-speed running stability. It is widely used in tissue paper, cultural paper, packaging paper and specialty paper production lines.
Standard vacuum transfer rolls often suffer from web slipping, uneven dewatering, pulp sticking, corrosion, coating peeling and frequent paper breaking. Jinan Tianmeng provides fully customized vacuum transfer rolls with custom dimensions and condition-based coatings. All rolls are tested and verified on-site, delivering stable performance and high customer satisfaction.
Custom Non-standard Size: Customize length, outer diameter, wall thickness, vacuum hole arrangement, shaft structure and flange size according to customer drawings or original roller data. Perfect fit for new, old and imported equipment without modification.
Working-condition Custom Coating: We select professional functional coatings based on line speed, paper grammage, pulp property, humidity and vacuum pressure to solve slipping, sticking, corrosion and abrasion problems.
Coating Type | Key Performance | Applicable Conditions | Paper Types | Operation Effect |
|---|---|---|---|---|
General Wear-resistant Coating | High hardness, strong adhesion, cost-effective | Medium-low speed, stable and mild working environment | Cultural paper, packaging paper | Keep roller surface smooth and vacuum holes unblocked, ensure uniform dewatering |
Anti-slip High-friction Coating | Controllable friction, stable paper gripping, no slipping | High-speed thin paper production, easy web floating | Tissue paper, thin paper | Effectively prevent web slipping, floating, wrinkling and paper breaking at high speed |
Anti-stick & Self-cleaning Coating | Smooth surface, no fiber adhesion, anti-clogging | Fine pulp, easy sticking and hole-blocking conditions | Specialty paper, high-grade paper | Reduce cleaning frequency, eliminate paper defects caused by pulp accumulation |
Moisture & Corrosion Resistant Coating | Waterproof, anti-rust, acid & alkali resistant | 24h high humidity, white water corrosive environment | All wet-end paper types | Prevent rust, pitting and coating peeling in harsh humid conditions |
Impact & Scour Resistant Coating | High toughness, anti-scouring, anti-impurity abrasion | Recycled pulp, high impurity and heavy wear conditions | Carton paper, recycled paper | Avoid groove wear and hole deformation, greatly extend service life |
All customized vacuum transfer rolls support on-site trial operation. With high concentricity and uniform vacuum suction, the rollers ensure stable web transfer, no floating paper, no breaking paper and uniform dewatering. Global customers confirm that our custom rolls have 2–3 times longer service life than standard rollers, significantly reducing downtime and maintenance costs with high repurchase rates.
1. Web slipping and floating at high speedSolution: Adopt custom anti-slip coating to stabilize paper gripping.
2. Pulp sticking and frequent hole blockingSolution: Apply self-cleaning anti-stick coating to keep vacuum holes unclogged.
3. Rust and coating peeling in humid environmentSolution: Equip with professional anti-corrosion coating for wet-end conditions.
4. Fast wear in recycled paper productionSolution: Use anti-scour and high-toughness coating to resist particle abrasion.
5. Uneven dewatering and paper wrinklesSolution: High-precision custom roller with condition-matched coating ensures full-width stable suction.
We provide one-stop export solutions including working condition analysis, custom size & coating design, precision processing, dynamic balance correction, quality inspection and global delivery. OEM & ODM orders are welcome.

Jinan Tianmeng thermal spraying industry leader, the workpiece surface long-term anti-corrosion, wear resistance, key parts repair and other technologies were established. The company is committed to the development and construction of spraying technology, with more than 30 years of industry experience and advanced complete sets of equipment. As a leader in thermal spraying, we build a leading position in surface spraying with excellent quality. For the damage and corrosion of the surface of the vacuum suction roller, our professional thermal spraying construction personnel decided to adopt the supersonic spraying tungsten carbide coating process for repair in view of the use environment of the workpiece. The supersonic spraying technology itself is known for its high speed, high spraying particle speed, the formed coating is denser and the binding force is strong. Tungsten carbide is a high-hardness, wear-resistant material, and the combination of the two should significantly improve surface properties.
The perfect combination of the two improves the wear resistance of the workpiece, corrosion resistance, strong coating bonding force, extending the replacement cycle, reducing maintenance costs, etc., compared with ordinary spraying or electroplating, supersonic spraying low-temperature spraying reduces the thermal effect, which is very important to maintain the performance of the substrate, especially the metal substrate is easy to deform or soften at high temperatures. A dense coating also means better corrosion protection, which is important for equipment in humid or corrosive environments.
Choose Jinan Tianmeng Technology Co., LTD., you will get quality repair services and good use experience. We look forward to working with you to protect your equipment together!
