Briefly introduce: Which parts of paper production line equipment belong to wearing parts?

The wearing parts of the paper production line are mainly concentrated in the parts that run at high speed, come into direct contact with paper materials and bear friction/pressure/high temperature. The wearing parts in different sections have their own characteristics, which are simply classified as follows:

1. Slurry preparation-flow delivery system

Sieve plate, rotor, grinding plate and cutter head

Mechanical seal, bearing, impeller and sheath of pump.

Wear-resistant bushing for pipeline and valve seal

2. Mesh section (forming section)

Forming screen, adhesive layer of guide roller, wiper, water suction box panel.

Vacuum roller airbag, sealing strip, bearing

Corrector, tensioner rubber strip and rubber block

3. Press section

Press felt, paper guide rope, scraper, scraper blade

Rubber roller coating, shaft head seal, bearing

Vacuum box panel, spray nozzle

4. Drying Department

Dry net, canvas, high temperature seal, spring, fastener.

Drying cylinder steam head seal, bearing, steam trap

Scraper, rubber layer of idler, tension piece

5. Calendering & Reeling Department

Calendering roller coating, bearing

Coiling cots, pneumatic tires, pneumatic seals.

Paper cutter, cutter bar, belt, friction plate

6. General wearing parts (universal across the board)

All kinds of bearings, oil seals, sealing rings and O-rings

Belt, chain, coupling elastomer

Nozzle, filter element, pneumatic/hydraulic components

Summary: Mesh, blanket, roller surface, scraper, seal, bearing, nozzle and pump are the most typical and frequently replaced vulnerable parts in papermaking line.
