Preparation of raw Material
Wood that has been received at a pulp mill can be in different forms. It depends on the pulping process and the origin of the raw material. It may be received as bolts (short logs) of round-wood with the bark still attached, as chips about the size of a half-dollar that may have been produced from sawmill from debarked round wood elsewhere.

If round wood is used, it is first debarked, usually by tumbling in large steel drums where wash water may be applied. Those debarked wood bolts are then chipped in a chipper if the pulping process calls for chemical digestion. Chips are then screened for size, cleaned, and temporarily stored for further processing.

Separation of Fiber
In the fiber separation stage, several pulping technologies will be diverged. The chips are kept into a large pressure cooker (digester), into which is added the appropriate chemicals in kraft chemical pulping.

The chips are then digested with steam at specific temperatures to separate the fibers and partially dissolve the lignin and other extractives. Some digesters operate continuously with a constant feed of chips (furnish) and liquor are charged intermittently and treat a batch at a time.

After the digestion process, the cooked pulp is discharged into a pressure vessel. Here the steam and volatile materials are tubed off. After that, this cooked pulp is returned to the chemical recovery cycle. Fiber separation in mechanical pulping is less dramatic.

Debarked logs are forced against rotating stone grinding wheels in the stone ground-wood procedure. Refiner pulp and thermo-mechanical pulp are produced by chips. These chips are ground by passing them through rapidly rotating in both processes.

In the second stage after refining, the pulp is screened, cleaned, and most of the process water is removed in preparation for paper making.

Bleaching Process
Raw pulp contains an appreciable amount of lignin and other discoloration, it must be bleached to produce light colored or white papers preferred for many products. The fibers are further delignified by solubilizing additional lignin from the cellulose through chlorination and oxidation. These include chlorine dioxide, chlorine gas, sodium hypochlorite, hydrogen perioxide, and oxygen.

Sodium Hydroxide, a strong alkali is used to extract the dissolved lignin from fibers surface. The bleaching agents and the sequence in which they are used depend on a number of factors, such as the relative cost of the bleaching chemicals, type and condition of the pulp.

Mechanical pulp bleaching varies from chemical pulp bleaching. Bleaching of mechanical pulp is designed to minimize the removal of the lignin that would reduce fiber yields.

Chemicals used for bleaching mechanical pulps selectively destroy coloring impurities but leave the lignin and cellulosic materials intact, These include sodium bisulfite, sodium or zinc hydrosulfite (no longer used in the United States), calcium or sodium hypochlorite, hydrogen or sodium peroxide, and the Sulfur Dioxide-Borol Process (a variation of the sodium hydrosulfite method).

Papermaking Procedure
Bleached or unbleached pulp may be further refined to cut the fibers and roughen the surface of the fibers to enhance formation and bonding of the fibers as they enter the paper machine.

Water is added to the pulp slurry to make a thin mixture normally containing less than 1 percent fiber. The dilute slurry is then cleaned in cyclone cleaners and screened in centrifugal screens before being fed into the ‘wet end' of the paper-forming machine. The dilute stock passes through a head-box that distributes the fiber slurry uniformly over the width of the paper sheet to be formed.

Tissue paper making machines are widely used in various industries for producing tissue papers. To ensure the smooth operation and longevity of these machines, regular maintenance is essential.

1. Lubrication
Proper lubrication is crucial for the efficient functioning of the machine. It is recommended to lubricate the key components such as bearings, gears, and chains regularly. Lubrication not only reduces friction but also prevents wear and tear, ensuring the smooth movement of parts. Make sure to use the appropriate lubricant specified by the manufacturer and follow the recommended lubrication intervals.

2. Cleaning
Cleaning the machine on a regular basis is vital to remove dust, debris, and residual paper fibers that may accumulate during operation. Use a soft cloth or brush to clean the surfaces of the machine. Pay special attention to the cutting blades, rollers, and other moving parts. Additionally, it is important to clean the paper path and remove any jammed paper to prevent further issues. Always remember to turn off the machine before performing any cleaning tasks.

3. Regular Inspection

• Performing regular inspections helps identify potential problems before they escalate into major issues. Inspect the machine for loose or worn-out parts, abnormal noises, and signs of damage. Check the tension of belts and chains, and adjust if necessary. Verify the alignment of the rollers and ensure they are parallel to each other. Keep an eye on the condition of the cutting blades and replace them if worn out. By conducting thorough inspections, you can address minor problems promptly and avoid costly repairs.
• Maintaining a tissue paper making machine is essential for ensuring its optimal performance and durability. Regular lubrication, cleaning, and inspections are key aspects of maintenance. By following these tips, you can extend the lifespan of your machine and minimize downtime. Remember to always refer to the manufacturer's guidelines for specific maintenance instructions. With proper care, your tissue paper making machine will continue to produce high-quality tissues, contributing to the success of your business.
