Applications of Inflow Screen Basket and Rotor
Inflow pressure screen basket and rotors (with the rotor located outside the screen basket) are the core components of inflow pressure screens. As an advanced modern pulp screening equipment internationally, it features high screening quality, large processing capacity, and low pulp pulsation. It is suitable for the fine screening of wood pulp, various types of straw pulp, and waste paper pulp, and is especially suitable as a pre-screening device for paper machines.
Inflow pressure screens are used for fine screening and pre-screening of pulp in pulp and paper systems. The equipment mainly consists of a housing, rotor, screen basket, transmission device, lifting device, etc.
The Advantages of Inflow Screen Baskets and Rotors in Pulp Production
- High Screening Efficiency: Due to the high pressure of the pulp entering the screen along the tangent line, it is subjected to centrifugal force. Before entering the screen basket, the fibers and coarse impurities of the pulp have already been separated. Qualified fibers quickly pass through the screen basket by relying on the pressure difference between the inlet and outlet of the pulp.
- Long Service Life of Screen Basket: Due to the centrifugal effect, heavy impurities in the pulp are separated after entering the pressure screen, which reduces the impact and wear of impurities on the rotor and screen basket. Extended the service life of the screen basket.
- Non Clogging During Pulp Screening: The pulp is evenly screened from top to bottom without thickening, and impurities are kept away from the screen basket, making it less prone to clogging.
- Can Replace Low Pulse Screening: This machine has low pulse intensity for good pulp and does not generate disturbance when directly connected to the internet.
- The quality of the pulp is good, and the screen basket is made of stainless steel precision. The finer screening slots greatly improve the removal rate of harmful impurities in the good pulp.
- Low maintenance costs: The spindle adopts advanced mechanical sealing system, which is not easily damaged.

Applications and Characteristics of Outflow Pressure Screen Baskets and Rotors
The outflow pressure screen is suitable for screening wood pulp, various types of straw pulp, and waste paper pulp before bleaching, and for selecting pulp in front of the headbox of the paper machine. The surface of the stainless steel screen basket is treated with chrome plating, which is wear-resistant, has a large throughput, and high screening efficiency; There is a light slag discharge outlet at the top, which eliminates some light debris and adhesive materials without passing through the screening area, making it particularly suitable for waste paper pulping; The bottom dilution water design greatly improves production capacity and effectively prevents blockages.
Out flow pressure screen, rotor wing is inside of Screen cylinder, pulp enter first into the inside of Screen cylinder, fine pulp flow outside the Screen cylinder with the effect of rotor wing. It is called Outflow Pressure Screen.
