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
来自称重输送带的颗粒分送至料仓皮带，准备分层叠加到铺装带上。
Main challenges
- Sticking issues
Solutions
- Flexam and Ropanyl belts have excellent release properties
铺装带是刨花板生产的核心输送带，直接运行到压机的位置。MDF（中密度纤维板）、PB（刨花板）的木纤维和 OSB（定向刨花板）的条状薄片都要通过铺装线运送。
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
松散的板坯必须首先通过预压系统，在铺装带和透气带之间进行压缩。透气带可帮助将空气挤出板坯。
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
经过预压之后，将板输送到压机站，切割成板并送入压机。巨大的圆柱辊筒将板压制成最终的形状和密度。
Main challenges
- Splices fail due to glue pollution
Solutions
- Our ZipLink® fabric uses monofilament so glue cannot penetrate the splice
板坯加热是一种特殊的进料系统，采用上下两条输送带并同时从上下两侧将蒸汽注入板坯，可将生产流程加快 10-30%。
Main challenges
- Product sticks to belt
Solutions
- Our Fabric EZP belt without silicone coating overcomes sticking
板材经过压制之后，输送到巨大的冷却轮（也称为星形翻板机）处进行冷却（通过空气冷却）并翻转。
Main challenges
- High temperatures reduce belt lifetime
Solutions
- ZipLink® carboxylated Nitrile belts are made for heat & wear resistance
此时可对成品板材进行存放，需要将其移动到存放位置。
Main challenges
- Aggressive release agents and heavy operational demands reduce belt lifetime
Solutions
- We have belts with excellent chemical and wear resistance
