THE BLOW ROOM

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.

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.

Basic Operations In The Blow room

Opening Cleaning Dust Removal Blending Even feed of Material to the Card

Operating Zones of Blowroom

Sequence Of Machines

Automatic Bale Opener

Functions Of A Bale Opener

Opening Of the baled stock.

Initial fiber Blending.

The Step Cleaner

Dual roll cleaner (Axi-flo)

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.

Multi mixer Trutzschler MPM 6

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.

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.
