Many modern papermaking machines are based on the principles of the Fourdrinier Machine, which uses a specially woven plastic fabric mesh conveyor belt (known as a wire as it was once woven from bronze) in the forming section, where a slurry of fibre (usually wood or other vegetable fibres) is drained to create a continuous paper web. After the forming section the wet web passes through a press section to squeeze out excess water, then the pressed web passes through a heated drying section.
Leizhan products play an important role in nearly every stage of papermaking and paper recycling, enhancing process efficiency and product quality for our customers. Leizhan products and technologies help to reduce energy consumption, improve water management, and enhance efficiencies for long-term sustainability. The primary product lines for papermaking is mainly about: Stock preparation systems for recovering and processing fiber.
Leizhan Stock preparation systems includes: M.C. pressure screen, Inflow pressure screen, pulp pump, waste paper chain conveyor, baler breaker, reject separator, light impurity separation, high and low density cleaner, etc.
Paper Machine operational sections/component
The original Fourdrinier forming section used a horizontal drainage area, referred to as the drainage table.
Paper machines have four distinct operational sections:
1, Forming section, commonly called the wet end, is where the slurry of fibres filters out fluid a continuous fabric loop to form a wet web of fibre.
2, Press section where the wet fibre web passes between large rolls loaded under high pressure to squeeze out as much water as possible.
3, Drying section, where the pressed sheet passes partly around, in a serpentine manner, a series of steam heated drying cylinders. Drying removes the water content down to a level of about 6%, where it will remain at typical indoor atmospheric conditions.
4, Calender section where the dried...
