Automatic air bellows guide most suitable for your wire, press part & dryer sections.
one of the basic principle of the extractor press says: is to squeeze out as much water as possible, where the wet fibre web passes between large rolls loaded under high pressure.
in mould plant, removal of water, from the wet web through press section is very important. extractor press is the only press with works at 8% (1%) consistency & that is the only reason. extractor press is selected as the 1st de-watering equipment in mould plant. in this process, bottom mould having a wire mesh of 40 & top roll is of bd. so both will have a technically self-explanatory easy water removal, without having a problem of web crushing.
