Non-woven Mill Roll - Car Application

Non-woven Mill Roll - Car Application

Introduction of materials of each brand

Japanese materials characteristics: Ultra-fine fiber materials are used, which have high requirements for the adsorbed liquid medium. Under complex working conditions, fiber detachment is likely to occur. The arrangement and combination is a hierarchical cross-form with good resilience.

American ** brands materials characteristics: Mainly uses DuPont nylon medium-coarse fiber, its main characteristics are good air permeability, good adsorption of liquid media, and a relatively wide range of media requirements; it is mainly arranged crosswise in the horizontal and vertical directions, has good tear resistance, and has a certain degree of resilience.

Taiwan HDE materials characteristics : DuPont nylon crude fiber is used. Its main characteristics are good water permeability and air permeability. Generally, it does not have high requirements for liquid media. The arrangement and combination are irregular forms. The biggest advantage of this arrangement is that it can resist extrusion, stretching and tearing in any direction, and has good resilience.

Main parameters of HDE roller

Line pressure and winding calculation

E: Young's modulus (elastic modulus) of steel (Kgf/cm3)

I: moment of inertia (cm4)

Solid shaft:

R=shaft radius (cm)

Tube axis:π/4*(R4-r4)

R=tube outer diameter (radius)

r=tube inner diameter (radius)

W: Line pressure (kgf/cm)

(2*P+roller weight)/roller surface length

Winding amount δ={(5*W*L4)/(24*E*I)}*(1+12/5*a/L)

Roller repair process

1. Old roller inspection
