MANUFACTURING PROCESS

The paper mill will use 100% re-cycle paper (waste paper) as raw material for Kraft Liner and multilayer Kraft Fluting Media paper of various grammage.
The Waste Paper supplied by dealer is stored according to grade and qualities. The waste is pulped by adding water in the Pulper and pumped to storage tank. Since waste paper contains impurities like plastics sand iron clips etc. The fiber has to be separated from the contraries.

To achieve this objective, various cleaning processes are adopted such as
separation of heavy plastic, metal clips, stones etc, on high density cleaner, Turbo Separatorvibrating screen etc. The pulp is then pumped to another tank after this process. The Pulp will be processed through 6 Tanks of 50 cubic metres each. The pulp is further diluted and sent to centric cleaner to remove heavy particles like sand which are separated from the pulp by centrifugal force. The cleaned pulp is thickened to the required consistency with the help of drum thickener which separates pulp from water. The thickened pulp will have lumps
which have to be broken into separate fibers. This process is known as refining. After refining the pulp has to be mixed with required dyes, chemicals & other additives before sending to the paper machine.

In the paper machine the pulp is again diluted in water and spread on the moving
(Pressurized) Alip Formers. The dilute pulp flowing on the wire mesh over the Cylinder in the Former drains the water from pulp & a sheet of pulp is formed and transferred on the felt. The sheet then will be transferred to the press section where the sheet is pressed between two felts with the help of rolls, this process is done in to two /three stages by applying different pressures gradually so that the sheet is not damaged.

After the process of pressing is completed no further water removal is possible by mechanical means and heat has to be applied to evaporate water from the sheet & this is done with the help of dryers. The dryers section comprises of series of steam heated dryer cylinders partly covered with dryer felt/dryer screen & when the sheet is moving between heated cylinder & felt the sheet also gets heated & water is evaporated. This process is done gradually heating in each cylinder till total water is evaporated from the paper.

After drying the sheet gets enough strength. To even out & smoothen its
surface, the sheet is then passed between numbers of steel rolls which is known as calendering.

After calendering the paper is wound on the Pope-reeler and periodically the
rolls are wound for further process.Then it is transferred to where the product is cut into required deckle. Finally the craft rolls are inspected & weighed. The Product is ready for dispatch.
