  The Full Circle Translucent on the Felt When this happens, check whether there is impurities in the pastern axes or whether there is a hard spot on the felt guide roller.   Felt Fluff on the Felt Vertical fluffing generally caused by the unclean felt roller surface or rough vacuum suction box panel, may be local fluff or the whole fluff; Transverse fluff may be caused by the desynchrony of felt and press roll in press section.   The Break of the Felt warp and weft The break of the felt warp and weft is usually caused by the damage of hard objects. Sometimes the pulp bolts may made holes on the felt. Also, the fine hard objects such as sand, broken glass in the pulp will make the felt strength decline, the felt warp and weft break. Flakes or punctate appeared in felt, warp and weft broken, may be caused by chemical corrosion, which is low fiber strength. The break of edge warp mostly due to friction with the rack because that the felt is too wide.   Beijing PFM Screen  offers dryer fa

As a   press felts supplier , I'd like to introduce it to you.   What is a Paper Making Machine Felt? Paper Machine Clothing Single Layer BOM Press Felts Paper machine felt is a material used in the paper industry. It is mainly used for paper sheet forming, wet paper sheet dewatering and paper sheet transportation. Paper machine felts have good dewatering, smoothness, abrasion resistance, stability and other characteristics. Generally, the paper making felt can be divide three types: wet felt, upper felt and dry felt according to the uses.   The Advantages of Paper Making Machine Felt 1. High anti-compaction capacity. 2. Long-term abrasion resistance and plasticity of of felt. 3. Extremely high elasticity and recoverability. 4. The felt is smooth and the pressure is evenly distributed. 5. Strong drainage capacity and larger void volume.

  Single Layer Forming Fabric 5. Guide roller winding pulp: the cleaning water pressure is low and there are many fibers inside the net; the net air permeability is low; there is a problem with the cleaning method. The two and a half layers of the net should be cleaned on the paper outlet surface of the net. Whether the nozzle is clogged, the best distance between the nozzle and the net surface is 15 -20cm.  6. Vacuum box top slurry: improper mesh air permeability, short slurry fiber loss, poor quality of retention aid or small addition amount. 7. Large fluctuation range when the net is running: the corrector is not working properly, and the side cutting of the net is not straight. 8. The net becomes narrow after using for a period of time: local wear of the forming plate, wiper board, vacuum box panel or guide roller causes the marking line of the net to run for a period of time to become slanted. 9. Comparison of the life of the D-type device and the previous net: The addition of the
