kraft paper making production line wire section parts Low Vacuum Suction Box
It is a kind of traditional vacuum dewatering element of paper machine, the general assembly quantity is 2-11. The vacuum suction box is located at the rear of the fourdrinier table, between the vacuum couch roll and the wet suction box.
The structure design is reasonable and it is a sealed structure. It is sucked by a vacuum pump to make the paper sheet from low-pressure dewater to high-pressure rapid dewater, thereby speeding up the drying of the sheet, enhancing the dewater effect and forming the sheet.
Features
