3. Problem Statement
The blow room is the first step of yarn
manufacturing in spinning mills. Bales are
taken to the blow room and prepared for the
process.
 Blow room is the backbone of yarn
manufacturing process, For that we can find
out its importance and trying to understand all
the processes which are done in blow room.


4. Aims and Objectives
 To understand the major operations of
Blow room.
 To investigate the working principle of
Blow room machinery.
 To find out the proper layout of Blow room.

5. Basic Operations In The Blow room
 Opening
 Cleaning
 Dust Removal
 Blending
 Even feed of Material to the Card

6. Operating Zones of Blowroom

7. Sequence Of Machines

8. Automatic Bale Opener

9. Functions Of A Bale Opener
 Opening Of the baled stock.
 Initial fiber Blending.

10. The Step Cleaner

11. Dual roll cleaner (Axi-flo)

12. Pre-cleaning
Pre-cleaning of material is done when
it is in free flight
The striker elements are widely spaced
on the operating rollers
The opening effect is correspondingly
small
Examples of machines are step cleaner
and axi flo.

14. Blending
When we use different types of fibers
it´s necessary to make blend with exact
proportion of each component.
Usually used technique is combination
of bale opening, blending, feeding and
opening process.

15. Conclusion
At the end of that project it is quit clear
that how the different machineries of
blow room are work.
 It is also helpful to understand
working principle and layout of blow
room.
 The three aims which were set in the
beginnings are achieved.
