High Performance Foil Rotor Improves De-Ink Pulp Screening

To improve the power-capacity relation of a screen rotor, several studies have examined the effect of rotor foil design on the magnitude of the negative pressure pu lse [1-3]. The "angle of attack" was identified as a key parameter in rotor foil performance, and it is the angle formed between the chord of the foil and the,CHAPTER 4. SCREENING ANALYSIS TABLE OF CONTENTS,The end rings create an electrical connection between the rotor bars. Increasing the size of the end rings reduces the resistance and thus lowers the I 2 R losses in the end rings. Considering the four screening criteria for this technology option, DOE did not screen out increasing end ring size as a means of improving efficiency.,DISC SCREEN FUNDAMENTALS – Recycling Product News,The screen should have an integral infeed impact plate above the first rotor to bridge the gap between the screen end plate and the first rotor. The impact plate must be profiled with fingers that fit closely to the discs and collars of the first rotor and should be sloped, the intent being to deflect long slivers horizontally onto the screen.

Plug flow versus mixed flow modelling of a pressure screen

Plug flow screening is also called series screening. Screens with closed rotors, like the bump, S-rotor and closed foil rotor are more likely to exhibit this behaviour. For the case of plug flow screening no axial mixing is assumed to occur in the screening zone (i.e. no mixing along the screen), and perfect radial mixing is assumed between the rotor and the screen plate (see Figure 5). A differential mass balance over an element of thickness,Screening and fractionation | Voith,The centrifugal screening principle with the rotor on the inlet side gives outstanding screening results. As with the IntegraScreen, the flow-optimized machine housing contributes to the efficient screening process of MultiScreen. By using a MultiFoil rotor and C-bar screen baskets, the screening is efficient and free of malfunctions.,Optimization Solutions for Pulping | Voith,The condition of the screen plates and rotors is elementary for an economical and efficient operation.
