Non-woven Mill Roll - Car Application

Non-woven Mill Roll - Car Application

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

2. Confirmation of repair plan

3. Replacement of damaged parts

4. Turning and grinding of roller surface

5. Performance inspection
