section

Couch roll

Effective dewatering effect, corrosion resistance

Vacuum couch roll

Φ500mm-Φ1500mm, width 2000mm-8000mm, thickness 30mm-120mm, hole diameter Φ3mm-Φ13mm

Guide roll

High temperature, corrosion, tension, pressure and impact resistance, easy to scrape.

Forward roll

Used in the rugged environment of driving unit, good frictional behavior and wear resistance.

Press section

Suction press roll

(SS shell)

The glue layer has good toughness, large tapping area (max: 50%); special designed buffer layer can disperse stress and resist impact; well dewatering effect; high quality paper product; prolong the service time of felt.

Suction press roll

(copper shell)

Stable hole pattern, excellent dewatering effect, stable hardness after long service time, wear resistance and corrosion resistance.

Soft top press roll

It has superior characteristic of releasing paper; wear, corrosion and impact resistance

Hard top press roll

It has superior characteristic of releasing paper; stable hardness under high temperature; good bearing capacity under the operation of vapor spray, chemicals, high pressure and scraper operation.

Grooved roll

Excellent wear resistance,dewatering performance

Blind press roll

Liner pressure can reach 380KN/m; the surface of the coated area has 21%-23% tapping; the speed is about 1000m/min; special bonding system ensures the safe operation under high speed and high linear pressure; good wear resistance, effective dehydration

Plain press roll

Good wear resistance

Artifical stone roll

Good paper releasing; wear resistance; scraper can be used; can satisfy severe rugged environment under high linear pressure

Guide roll

Good paper releasing; wear resistance

Spreader roll

Good wear resistance and frictional behavior

Pick up roll

Good paper releasing, anti-adhesive capacity; wear resistance

Stone roll

Compression strength: 200mpa; tensile strength: 70mpa; modulus of elasticity: 0.4*106E; rigidity: HV3500

Drying section

Hard breaker stack roll

Super wear and high temperature resistance; uniform surface

Soft breaker stack roll

Super wear and high temperature resistance; good after-hardening resistance

Sizing/ coating section

Coating roll

Super wear resistance; good reinstatement and tread forming resistance; uniform surface; good wettability; high temperature and corrosion resistance; longer operational  period; reduce downtime

Sizing roll

High temperature, wear, corrosion, thread forming resistance; good reinstatement; uniform and stable size; longer run operational period.

Calender  section

Calender roll

The use of nano material improves the performance of rubber significantly. Meanwhile, improves its elastic modulus and its impact resistance. It can keep safe performance although in severe rugged environment of high speed, high temperature, and high linear pressure. At the same time, roller surface lasts stability, good abrasion resistance, and a long grinding cycle.

Reeling end

Spool

Good wear and tear resistance
