Double width Flow_on machine

Some technical man want to know the double width flow on machine information. here is some pics 1: The Double width flow on machine felt width is 2.9 meter ,always felt length is 29.5M or 33M 2: Total 9 vacuum box for board dewatering and 1 vacuum box for felt clean 3: Each time the forming roller will forming 4 pieces board  with size: 2440*1220 4: Speed is always 70-80M/MIN 5: No asbestos 6: In china ,now total 9 lines(5 factory 3+2+2+1+1=9) running with this type.

Caution when using fiber cement felt

High acid concentrations on the felt. when washing the felt, carefully dilute with water. Because of the FC felt is PA6 or PA66. Flocculants concentrations Huge quantity of flocculants leads to early clogging of the felt due to the high PH value on the felt itself. Flocculants not diluted properly can cause stains on the felt where subsequently there would no drainage. Felt stretcher If the pressure on the felt stretcher is pneumatic or hydraulic, keep control of the adjusting devices to avoid excessive pressure. The recommended tensions, depending on machine configuration, speed and production, can range from 2 kg per linear cm. after the forming bole up to 4 kg per linear cm. over the film drying vacuum boxes and before the forming roller. Automatic felt guide – must always be well adjusted so it doesn’t correct the felt at intervals too long which could cause the felt to get folded. Scroll roll – if necessary, we advise that the same be of rubber material. Suction box cover – it is advisable that they be made from ultra-high molecular weight polyethylene(UHMW-PE) to avoid contents of hard or ferrous micro- particles that come from recycled resins that can damage the felt
