The pressure screen rotor rotates inside or outside the screen basket, and the rotor on the rotor runs close to the screen basket. At the front of the rotor, the rotor exerts pressure on the pulp, allowing the pulp to pass quickly. At the rear of the rotor, a negative pressure is formed, and the purified slurry backwashes the screen basket to prevent the screen holes from being blocked.
The pressure screen rotor adopts the upflow structure design of bottom slurry feeding, heavy slag discharge at the bottom, and light slag discharge at the top to effectively solve the above problems.
Light impurities and voids in the slurry naturally rise to the top slag discharge port and discharge, and heavy impurities-enter the body and can settle to the bottom to discharge.
In this way, on the one hand, the pressure screen rotor effectively shortens the residence time of impurities in the sscreen area, reduces the possibility of impurity circulation, and improves the screening efficiency.
On the other hand, it prevents damage to the rotor and the screen basket caused by heavy impurities, and extends the Service life.
Two Types of Screen Basket
Wedge wire screen baskets is classified by the flow way of the pulp, the rotary wing spins in the basket to make the pulp flow out from the slot naturally to get good pulp with different purpose.
Drilled screen baskets are manufactured with CNC-controlled, multi-spindle drilling/milling machines. Drilled screen can optionally have breaker bars or a reject spiral, and there are different profile types and open areas available for all applications and process requirements.
