The NLS type internal flow pressure screen (the rotor is outside the screen drum) is an ideal papermaking screening equipment in the modern world. It has the characteristics of high screening quality, large capacity and low pulp flow pulse. It is suitable for wood pulp and various straw pulps. , waste paper pulp fine screening equipment, especially suitable as screen-front screening equipment for paper machines.
Outstanding advantages
The installed power is small and the energy saving effect is obvious. It is praised by users as "small appetite, big production capacity".
Internal flow structure, low pulse design, good web uniformity.
The slurry outlet adopts a diffusion design, a gasket-less matching flange, and the inner wall is polished to achieve seamless connection of the flow pipeline without hanging slurry.
The main engine and transmission adopt modular design, the structure is stable and reliable, and installation and maintenance save labor and time.
Equipped with automatic refueling and mechanical seal water flow monitoring devices, reserved bearing temperature rise, and vibration detection sensor interface with a high degree of automation.
