Water removal, wet press

Note: Using the press to overcome faults generated elsewhere in the machine system will lead to more trouble than it overcomes.
1. For machines with an open draw and a lump breaker roll (couch presser roll), crown on lump breaker roll must be correct.
— the rubber cover of the lump breaker roll may become harder as roll is ground down and in this case the crown must be changed.
2. Wet felts must be kept scrupulously clean.
— the continuous felt washing system must not be shutdown intermittently.
— ensure that felt is not soiled in process of installing it.
3. Wet felts must be operated with trade lines square and at correct tension.
4. The suction box and couching of top roll must be correct.
5. Maintain correct crown (camber) and apply pressure for which roll was crowned.
6 Ensure that box is seated properly across suction roll.
7. Ensure that press doctor fits all the way across.
8. Keep holes in suction shell open.
— make sure rubber cover is not too soft or the rubber will partially close the holes under pressure.
