Raw Material
I] Cloth Products : Drill Cloth.
II] Paper products : 150 GSM Paper.
III] Abrasive Grain : I] Aluminium Oxide. II] Silicon Carbide.
Adhesive & Grain Coating On Cloth/Paper
This process is the heart of the abrasive products. Adhasive coating process to
be done on the main coating machin, and after that the grain coating to be done
by electro/gravity method on cloth/paper. This process also require mixing plant,
steam boiler and phenolic/alkyd resin as adhesive.
Festoon Currying
The adhasive/grain coated cloth/paper to be curried in certain temperature & time
by circulating the hot air. this process must be done in loop (Festoon) form of
the cloth/paper this process require Hot air unit as well as Oven with chain conveyer
system (Depends upon required capacity of production).
Mixing plant
This plant is required for cloth processing process as well as adhesive coating
process. It is a mixing of fillers, adhesives, chemicals, at certain temperature
& viscosity.
Hot Air Unit
This unit is required for festoon currying purpose.
Jumbo Oven
This Unit is required for Jumbo Currying purpose.
Cloth Processing
For Paper Product there are no fillers but for the cloth product fillers are filled
on the back side. There are two sides of the cloth which are different form each
other. One side bears a net of fine lining if seen carefully and this side is called
drilled side of the cloth. Drill side is filled with fillers. The other side of
the cloth is called the coating side. This process can be done in adhesive coating
plant. But if the gray cloth purchases from the market, four processes we have to
do that is called cloth processing. The name of the process is bleaching, scouring,
sizing, dying etc. This process require mixing plant & steam boiler.
Sizing Coat
After the festoon currying for strong bonding of abrasive grain the sizing coat
(Second coat) to be done on sizing coat machine/oven.
Rewinding
For making the coated abrasive cloth/paper in jumbo roll from this process to be
done by rewinding machine.
Jumbo Currying
For Perfection of currying this process to be done in jumbo roll form of coated
abrasive cloth/paper.
Conversion
The coated abrasive cloth/paper to be convert in sheet, belt, disc, flap wheel,
etc. Form is called conversion process.
Phenolic /Alkeyd resin plant
This plant is required for manufacturing phenolic/alkeyd resin for quality product
maintaining the secrecy of the product.
