Actual factory and process configurations could vary, but our industry experts know them all.
Rotary dryers are the most commonly used dryer type in the particle board industry. The moisture content of the particles entering the dryers may be as high as 50% for wet particles. Drying reduces the moisture content to 2%-8%.
After the mega dryers, wood particles are first stored in the dry chip silo and then weighed. Belts for these applications should be ATEX-certified and have anti-static and flame-retardant properties.
Main challenges
- Dry chip silo: particles stick to belt
- Weighing belt: very little space to splice the belt endless
Solutions
- Our Flexam EM and EX belts are anti-static
- Our Silam EZP can be installed without disassembling the machine
Punnitushihnalta tulevat lastut jaetaan massan levityskoneisiin, missä ne valmistellaan ennen levityshihnalle levittämistä.
Main challenges
- Sticking issues
Solutions
- Flexam and Ropanyl belts have excellent release properties
Levityslinjan hihna on tärkein hihna lastulevyprosessissa. Se kuljettaa levyt suoraan puristimeen. MDF-, PB-puukuidut ja OSB-säikeet kulkevat kaikki levityslinjan kautta.
Main challenges
- The mat is very fragile before pressing and breaks easily
- Very heavy load – sometimes over two tons on the belt
- Dimensional stability is essential: belt must lay perfectly flat
- Material accumulation due to electrostatic charge build-up
- Glue adheres to the belt covers
Solutions
- Our belts deliver gentle handling and are suitable for small diameter transfers
- Our 2-ply (or DM fabric) is strong yet still flexible
- More wefts or greater monofilament thickness make our belts dimensionally stable
- High-quality carbon yarns ensure discharge of any static build-up
- Ropanyl EM m1 belt resists glue build-up
Hauraan kuitumaton on ensin kuljettava esipuristusjärjestelmän läpi, jossa se puristetaan muotoiluhihnan ja ilmanpoistohihnan välissä. Ilmanpoistohihna auttaa puristamaan ilmakuplat pois massasta.
Main challenges
- Friction and static cause particles to stick to the belt
- Air is pushed back into the fiber mat
- Belt splices fail
Solutions
- Our de-airing belts are made to let air pass through easily, preventing the particles from getting stuck in the belt fabric
- Pre-press belts can be perforated, allowing air to escape
- Our splice technology ensures a strong and lasting splice
Esipuristuksen jälkeen kuitumassa kuljetetaan puristusasemille, leikataan paneeleiksi ja syötetään monivälipuristimeen. Jättimäinen sylinteri puristaa levyt lopulliseen muotoon ja tiheyteen.
Main challenges
- Splices fail due to glue pollution
Solutions
- Our ZipLink® fabric uses monofilament so glue cannot penetrate the splice
Höyryinjektio on erityinen syöttöjärjestelmä, jossa käytetään ylä- ja alahihnaa höyryn injektoimiseen kuitumassaan. Tämä nopeuttaa tuotantoprosessia 10–30 %.
Main challenges
- Product sticks to belt
Solutions
- Our Fabric EZP belt without silicone coating overcomes sticking
Kun levyt on puristettu, ne kuljetetaan jäähdytettäviksi valtavaan jäähdytyspyörään.
Main challenges
- High temperatures reduce belt lifetime
Solutions
- ZipLink® carboxylated Nitrile belts are made for heat & wear resistance
Valmiit levyt voidaan nyt varastoida ja ne siirretään varastointipaikkaan.
Main challenges
- Aggressive release agents and heavy operational demands reduce belt lifetime
Solutions
- We have belts with excellent chemical and wear resistance
