ROLLERS FOR PAPER INDUSTRY

Premium range of covering compound

Paper Industry

              Based on roller operating conditions, ZENITH manufactures rollers for the paper sector. Large metal rolls (up to 10 metres long, 2 metres in diameter, and 50 tonnes WT) are manufactured, covered, and serviced using roll technology. Application, chemistry, speed, temperature, pressure, Roll geometry, deflection, balance, and coefficient of friction are all factors that influence roll quality. Among our offerings are:

1. New Core Design & Fabrication
2. Rubber Covering
3. Re-Grinds
4. Core Repair
5. Ultra sonic test & Balancing machine
6. Crowning
7. Grooving
8. Engineering Services
9. Extensive Field Support

DELIVERING DYNAMIC SOLUTIONS

Modern paper machines are built to manufacture/produce more at a faster rate. We have rubber-covering options that allow for optimum load usage without risk of crushing, as well as maximum covering resiliency, even at increasing hardness, in order to maintain a consistent Nip Zone.

Offering Polyurethane & Composite Covering World Class Technology

Polyurethane Covering

Prepared with Special elastomers which have abrasion resistance properties. Designed for high speed and high demanding paper machines. PU Covering has lot more advantages than rubber and has proved its superiority by providing longer life, longer grinding intervals, better resistance to hydrophobisity,

Composite Covering

The Covering is manufactured from state of the art
materials such as an optimized combination of thermoset epoxy resin with special fillers and fibers for best performance. Its benefits include:

  • Longer working life
  • Higher resistance to temperature (up to +100° and even more)

ROLLS COVERING

Zenith has created a Premium range of compound Excel, Ultimex, Super Rock, and Ultra Super Rock with superior release characteristics, dimensional stability, chemical resistance, steam environment, thermal stability, and high pressure operation.        The material can sustain a Nip Load of up to 500 kg per linear centimetre. The graph below shows the newly developed superior compound.

POLYURETHANE & RUBBER COVERING FOR SUCTION PRESS

The Suction Press (SP) Concept provides a considerable improvement in suction roll cover performance. SP is a computerised method developed by Zenith engineers that determines a precise hole pattern for a mix of blind and through drilled holes in the press nip to provide more symmetrical sheet dewatering. The assertions that most suction roll applications can benefit from talking to SP are backed up by field findings.

HYBRID COVERS FOR PRESS SECTION

SUPERFLEX BD

“Superflex BD is a special hybrid compound developed with Italian technology. It is made out of specialized rubber & polymers to achieve better and wider NIP, dewatering, high linear load and much better resilience as compared to normal rubber covers. ” Superflex BD cover has been developed for High Speed and Long Run machine.
