Paper is an important part of our daily lives, used for many industries. Especially, majors in literature, art, office documents, ect. Through paper, will have better memories in memory, easier to convey emotions, which is the strength of devices electronics are incomparable… But how is paper actually made? What types of machinery and equipment are used in paper production?
In this article, UNIOIL we would like to share with our customers information about all kinds of machinery and equipment in paper and paper production. Suitable lubricants for those machines and equipment to help customers choose some grease products suitable for high efficiency .
1. Paper production process
Paper is produced from two main materials: wood (cellulose) and recycled paper.
Several types of wood produce high-quality paper products such as spruce, pine, poplar, fir, oak, and eucalyptus. In addition, today, it is also possible to make use of agricultural by-products (biomass) to make raw materials for paper production.
Paper production line from 2 sources of raw materials are wood and waste paper:
Go through the following basic processing stages:
- Raw material processing stage: peeling, crushing, chopping
- Chemical treatment stage: using bleaching chemicals, cleaning, bonding
- Finished product stage: drying, rolling, pressing, coating
The technology of making paper from scrap and wood materials is different at the initial stage of raw material processing, the later stages are similar.
2. Some main equipment in paper factory
The types of machinery used in the paper factory depend on the source of the paper production material (waste paper or wood) as well as the production capacity of the factory.
- Material chopping machine
- Pulp Milling Machine
- Vibrating floor system
- Dryer system
- Mixing system
- Fiber Separator
- Pulp Pump
- Pressure floor
- Paper slitting machine
- Reel receiver, to roll
3. Lubricants used in paper mills
Pulp and Paper Factory is a complex manufacturing plant, with machines working in extremely humid, dusty and high temperature environments. Systems such as gears, bearings, hydraulic systems are always affected by these factors, reducing the effect of lubricating oil and hydraulic oil.
=> The Lubricants used must have the properties to withstand the wet, dusty working environment and good heat resistance
Characteristics of lubricating oil for paper industry
- Lubricating oil for the packaging industry has high load capacity, wide operating temperature range, and has anti-corrosion effect on equipment.
- Oil has good adhesion ability, low volatility helps to save costs.
- Oil has good lubricating ability to avoid scratching gears and pistons.
- Long-life oil, good anti-aging for equipment.
Hydraulic oil
Hydraulic oil: used in wood pulp mills, choppers, crane systems, presses…
According to calculations, raising the dryness of the paper to 1% after the pressing phase will help save 4% of the energy consumed in the drying phase. For the hydraulic system to work well and prolong its life, choosing the right hydraulic oil is very important
