1. what is the control system of the paper pulp pressure screen?

The pressure screen is to control the pressure and flow rate of cooling water of the mechanical seal. When the pressure or flow is insufficient, the pressure sieve pump and the main motor of the pressure screen can be stopped.

2. What's the type of rotor about pressure screen?

Convex block rotor with multiple rotors.

3. What's the screen drum material of pressure screen for paper pulping?

The material of the screen drum is 304 stainless steel or 316L stainless steel. The surface is hard chrome: 0.2mm.

4. what is the difference between the Inflow Pressure Screen and the Outflow Pressure Screen?

Inflow Pressure Screen: the rotor is outside the sieve drum , the slurry first into the sieve drum outside, the accepted pulp flows into the paper pulp drum screen in the role of the rotor wing.

Outflow Pressure Screen: the rotor is inside the sieve drum,  the slurry first into the sieve drum, and the good pulp flows to the outside of the drum screen under the influence of rotor wing.

The pressure screen for pulp and paper machine is silver gray canister, 304 stainless steel. The bottom plate is pressed and formed at once, and the transportation process can not be broken.The paper pulp machine pressure screen is used for enclosed screening flow for chemical wood, straw and reed pulp; and used for coarse screening and fine screening for wood, straw and waste paper pulp. 

Advantages of Pressure Screen

1. Medium consistency screening, simplied process, water and energy saving.

2. The pressure screen for pulp and paper machine is of precision process with combination of 3rd generation machining and auto welding, high strength of screen basket.

3. New pressure screen rotor structure and section, even distribution, efficient screening and high capacity.

4. The pressure screen basket is of latest cladding technology, precision and perfet process.
