Inflow Pressure Screen for Stock Preparation Line

The inflow pressure screen is installed at the approach flow stage to remove contaminants while providing a stable, low‑pulse stock supply to the headbox. Its inflow design ensures gentle fiber treatment and excellent homogenization. The companion flange pulp outlet has no gaskets, and the interior is polished for seamless connection – eliminating fiber hitching. An automatic oil injection device and seal water detection alarm reduce maintenance and protect the equipment. Compact, energy‑efficient, and easy to operate, this inflow pressure screen is ideal for fine screening of writing paper, tissue, and board grades.
