Pressure Screen Basket

Inflow wedge wire pressure drum screen basket is a screening tool in pulping equipment in the paper industry. It can be used not only for pulp screening before papermaking in the papermaking process but also for fine screening of waste pulp.
Therefore, there are two kinds of functions of pressure sieve screen in the papermaking process, namely pulp screening and waste pulp fine screening.

Slot Size

In the internal flow pressure screen, the size of the gap of the screen drum is a very important technical parameter.
The size of the screen gap (slot) determines the opening area of the screen. Generally, the larger the screen area of the pressure screen, the larger the gap size.

Pulp screening is an essential process in pulping. The pressure screen is one of the important equipment to achieve pulp screening. Its basic components are composed of a pressure screen basket and a rotor.
The type of pressurized screen and rotor determines the screening effect, screening capacity, and the operation of the screening system.

At the same time, the screening speed will also increase, but the quality of screening will be significantly reduced, so a secondary screening is required.

(open area rate = slot size / width of profile wire + slot size)

Applications

Slotted pressure screen baskets: used for fine screening, the screen slot is adjustable.

1. Separation of unwanted debris or contaminants from required fibers in paper pulp，Also widely used for fine screening of wood pulp, straw pulp, and waste paper pulp

2. paper machine thin-stock recirculation system。
Remove debris (fiber bundles) and other large hard contaminants.

Fractionation, fiber retention, water purification, cleaning dewatered pulp screens, drying, and other liquid-solid separation processes.
