Blow Room Technology
Blow Room
Blow room is the initial process of the spinning operation where
the fibre is opened, cleaned, mixed, micro dust removed and
evened thus passed to carding machine.
Objects of Blow room:
1. To open the baled fibres into small tufts.
2. To clean the fibres by removing the foreign matter as the
waste.
3. To mix thorough the different component fibres of a mixing.
4. To form a compact & uniform sheet of fibres called lap.
Basic operation in the Blow room:
1. Opening
2. Cleaning
3. Mixing or Blending
4. Micro dust removal
5. Uniform feed to the carding machine
6. Recycling the waste

Leaver’s are connected with inversion

One suction zone where the tuft cotton are thrown.
BlendomatBlendomat is a system in which, the bale is opened by
tufting.
It contains-
Working Principle
Here,
A and B are two roll’s which added teeth, C is the grid, 𝐷1,𝐷2, 𝐷3are the supporting roll’s and 𝐸1 and 𝐸2 are the leavers of A and B
roll connected with inversion mechanism.
Roll (A) and (B) with there fine teeth plug into the top
bale surface. The teeth actually pass through the sits of the
grid (C). Small tufts are picked by the teeth and are
thrown in the suction zone. Roll (A) and (B) work
opposite to each other. When A and B start tufting, both of
they are individually come down upto 10 m.m. on the
bale.

Tuftomat system
1. Modern tuft blending installations hold a key position in the value chain, because blending faults often become obvious only after finishing.
2. Trützschler tuft blending concept relies on reproducible top blend quality.
3. Ensures the perfect speed when blending natural and synthetic fibers of different lengths, fineness's and colours.
4. Mix six components in one process step and achieve optimal CV values.
Integrated Mixer
Advantage of Integrated mixer
Opening with optimum quality chain
Simple and secure operation
Large bale lay-down
Flexible layout of bale groups
Advantage:
High capacities up to 2,000 kg/h
Precise the blending ratio.
Blending of up to 6 components per process step
Automatic tarning.
A lot of change in recipe memory.
Direct measurement of weight

Uniclean / Pre cleaning
Since removing finer trash particles is difficult, seeds andbigger trash particles should not be broken. Due to treatthis problem we have to use pre cleaning/uniclean.
Unimix
The machine is made up of three parts
1. A storage section
2. An intermediate chamber
3. A delivery section
1 Material input;
2 Material discharge;
3 Opening rollers;
4 Feed rollers;
5 Perforated metal plate for air discharge;
6 Light barrier for monitoring material height;
7 Open exhaust air transfer
Storage and feeding machine UNIstore A 78
• The UNIstore A 78 is used as a storage, dedusting and feeder
machine in the blowroom.
• Its main purpose is to provide intermediate storage for
material in order to ensure trouble-free blowroom operation.
• The UNIstore A 78 is used where a mixing opener proves
unsuitable for financial, technical or technological reasons.
• The structure of the feeding and opening unit guarantees
gentle fiber opening.
• The UNIstore A 78 is used where a mixing opener proves
unsuitable for financial, technical or technological reasons.
• The integration of a mesh screen filter inside the UNIstore A
78 eliminates the transport air, and creates an efficient
dedusting.

6. Card C 60
• 1= Filling Chute
• 2= Perforated drum
• 3= Feed zone
• 4= Grid
• 5= Opening Cylinder
• 6= Delivery
• Maximum raw material utilization at carding output of up to 240 kg/h.
• The modular machine design reduces maintenance-related downtimes to a minimum. Efficient, gentle removal of trash particles facilitated by the higher centrifugal forces generated by the card geometry.
• Automatic sharpening of the card clothing with the Integrated Grinding System (IGS) for long clothing service life and consistent sliver quality.
• Gentle processing of man-made fibers and blends while meeting the highest quality targets
