What are the main equipments in the press department?

The core monomer equipment in the press section of paper machine mainly includes these, which are classified according to function and structure:

First, the core press rolls

Upper press roll

Lower press roll

Vacuum press roller (internal vacuum, enhanced dehydration)

Grooved press roll (grooved roll surface is beneficial to dewatering and reducing embossing)

Blind hole press roller (the roller surface is densely covered with small holes, which has good dewatering effect)

Shoe press roll/wide nip press (large nip, high press efficiency, commonly used in modern paper machines)

Second, the blanket related equipment

Press felt (transfer paper, support, dewatering)

Blanket tensioner

Blanket corrector (guide roller)

Blanket washing device (high pressure water washing, vacuum suction, etc., to keep the blanket breathable)

Blanket vacuum box

Third, the paper and auxiliary equipment

Paper guide roller

Spreading roll (to prevent paper from wrinkling)

Pressurization device (pneumatic/hydraulic pressurization system)

Scraper (cleaning roller surface and preventing roller sticking)

Wet paper suction device (vacuum suction roller for paper web transfer)

Iv. transmission and control

Press section transmission device

Load and pressure control system

Brief note: all kinds of press rollers+press felt and adjusting device+auxiliary equipment for pressure and paper introduction.
