The document discusses the components and functions of various machines used in the blowroom line of a textile mill. It describes the bale opener, coarse cleaner, blender, fine cleaner and their purposes of opening, blending, and removing impurities from cotton fibers. It also provides details on the working principles and parts of specific machines, such as the step cleaner, mono-cylinder cleaner, and axial flow cleaner.

5. BLOWROOM LINE CONSISTS OF
FOLLWING MACHINE:
 1. BALE OPENER( OPENING)
 2. COARSE CLEANER( REMOVES
COARSE TRASH)
 3.BLENDER ( HOMOGENEOUS
BLENDING)
 4. FINE CLEANER( REMOVES FINE

10.  Step cleaner machine is an important
machine in ring spinning for cleaning and
opening impurities from cotton. This machine
is set normally after porcupine opener
machine.

11.  OBJECTIVES:
 1. TO OPEN AND CLEAN THE COTTON
TUFT BY OPPOSITE SPIKES AND
BEATING ACTION.
2. TO REMOVE HEAVY IMPURITIES ,
SUCH AS LEAVES, STALK , MOTES SAND
WITHOUT DAMAGING THE FIBRE.
3. TO MAKE OR CONVERT THE COTTON
TUFT TO SMALL SIZE OF COTTON FIBRE.

12. 1. FEED ROLLER .
2. SIX BEATERS.
3. BAFFLE PLATE .
4. GRID BAR .
5. PHOTO-CELL.

14.  WORKING PROSEDURE:
1. THE COTTON OR MATERIALS FALLS INTO THE FEED HOPPER.
2. THEN IT PASSES TO THE FIRST BEATER.
3. AFTERTHAT IT IS TRANSPORTED UPWARDS BY THE SIX BEATER ROLLERS
WHERE EACH CARRYING PROFILED BARS AND BEATERS ARE ARRANGED
ON A LINE INCLINED UPWARDS AT THE ANGLE 45 DEGREE.
4. THE TRUSHES ARE EXTRACTED BY THE HELP OF OPPSITE SPIKE AND
BEATING FUNCTION EXTRACTS THE TRASHES AND FALLS INTO THE
CHAMBER THROUGH GRID BARS HOLE.
5. AFTER THAT COTTON TUFT OPENED AND MAKE SMALL SIZED TUFT
GRID BARS HOLE.
6. A BUCKLE IS IN THE MIDDLE OF PER TWO BEATERS AND IT CONTROLS
THE FLOW OF MATERIALS.

15.  Step Cleaner Main Setting Point :
Set to do the require amount as cleaning close grid bars, setting gives
good opening & large grid bar setting gives poor opening, other setting
points are, Beater to Grid bar = 1`` & beater to beater = 8``.

 Specification :
 Motor r.p.m = 695
 Dia of the beater = 18.6``
 Dia of two pulley = 21.2``
 Dia of one pulley = 16``
 No. of striker = 26

16.  Calculation :
 Beater r.p.m = 695*(16``/21.2``)
 = 524.5
 Beater per min. = 524.5*26
 = 13637
 Conclusion :
This is the second m/c of blow room line. It works step by step &
for this it is called step cleaner. It is a good instrument of
opening & cleaning of cotton by the action of beater. It also
removes ascertain a out of leaves, stalk & other impurities. It is
suitable for process of low grade cotton.

17.  A LARGE ROLLER EQUIPPED WITH
SPECIALLY DESIGNED PINS GUIDES THE
RAW MATERIAL SEVERAL TIMES OVER A
SET OF GRID BARS BETWEEN ENTRY AND
EXIT, WHICH RESULT IN A CLEANING
EFFICIENCY

18.  PARTS OF SINGLE ROLLER CLEANER :
1. CLEANING CYLINDER.
2. CLEANING GRID.
3. AIRLOCK CYLINDER.
4. MATERIAL FEED.
5. MATERIAL OUTLET.
6. EXHAUST AIR TO FILTER.
7. WASTE REMOVAL .

22.  WORKING PRINCIPAL:
THE MATERIAL PASSES SIMULTANEOUSLY
THROUGH A DUST EXTRACTION SYSTEM ,WHICH
RESULT IN A HIGH DEDUSTING EFFECT OF THE
MACHINE .
THE MATERIAL - GUIDANCE SYSTEM WITHIN
THE MACHINE IS PURELY MECHANICAL AND
INDEPENT ENT OF TRANSPORTION OF AIR . A
VACCUM SYSTEM WITH A LOCK ROLLER BELOW
THE MACHINE AUTOMATICALLY REMOVES THE

23.  THE MACHINES IN HIGH
CLEANING EFFICIENCIES
WITH THE LOWEST FIBRE
LOSS.

24.  MONO-CYLINDER IS A MACHINE IN WHICH
THE MATERIAL IS PROCESSED PARALLEL
RATHER THAN NORMAL TO THE ROLLERS TO
OPEN AND CLEAN THE COTTON.

25.  OBJECTIVES:
 TO OPEN THE COMPRESSED LAYER OF BALE COTTON OR STAPLE
FIBRES .
 TO BLEND DIFFERENT VARIETIES OF COTTON IN THE DESIRE
PROPOSION TO PREPARE THE RAW MATERIAL FOR THE SPINNING
PROCESS .
 TO EXTRACT THE IMPURITES (LIKE BROKEN SEEDS ,HUSKS ,LEAVES
ETC)FROM THE COTTON BY OPENING AND BEATING.
 TO COVERT THE MASS OF COTTON FIBRES INTO UNIFORM THICK
SHEET OF COTTON BOTH LONGITUDINALLY AND TRANSVERSELY
AND TO WOUND IN THE FORM OF COMPACTLY BUILD LAP .

26.  PARTS OF MONOCYLINDER:
1.SPIKED ROLLER.
2.ADJUSTABLE GRID.
3.PIN CYLINDER ( 8 ROWS OF 6
PINS).
4.INLET AND OUTLET.
5.WASTE BOX.

27.  WORKING PRINCIPLE:
 1. THIS MACHINE OPERATES IN A SIMILAR MANNER TO
THE DUAL ROLLAR CLEANER BUT HAS ONLY ONE DRUM.
 2.THE MATERIALS ENTERS THE MACHINE AT ONE SIDE
AND STREMS THROUGH TO THE OTHER SIDE.
 3.IN OREDR TO PREVENT FLOCKS BEING DRAWN
STRAIGHT THROUGH THE MACHINE , THE LARGE HOOD IS
DIVIDED INTO THREE CHAMBERS BY GUIDE PLATES.THIS
CAUSES THE FLOCKS TO FALL BACK INTO THE REGION
THE BEATER DRUM AFETR BEING HURLED OUT BY THE
ROLLER.
 4.THE FLOCKS THEN ARE FORCED TO CIRCULATE 3 TIMES
WITH THE DRUM i.e.TO PASS 3 TIMES OVER GRID;THIS
GIVES STRONG CLEANING EFFECT.

28. MONOCYLINDER CLEANER
MATERIAL FLOW IN THE
MONOCYLINDER

30.  The Axiflow is used to preclean
all kind of natural fibres , such
as wool, hemp, flax, kenaf, sisal,
jute, cocos i.e. in a continuous
way.

31.  OBJECTIVES:
 THE MAJOR OBJECT OF AXE-FLOW
CLEANER ARE OPENING AND
CLEANING . IT IS USED IN BLOWROOM
AFTER BALE BREAKER .
 THE FEEDING OF THE MATERIAL
TAKES PLACE BY MEANS OF AIR
CURRENTS PRODUCED BY A
CONDENSER.

32. The machine basically consists of:
1.DEFLECTOR PLATE.
2.Lamella devices, adjustable .
3.Cellular wheel sluice or Dirt collection
Box.
4. TWO BEATERS HAVING 6-8 ROWS OF SPIKES.
5.GRID BARS AND SCROLL BARS
6.DEFLECTOR PLATE.

33. 
1.This is also known as dual roller cleaner, used
for opening and cleaning purposes.
2.This has two beaters having 6-8 rows of
spikes with flattened edges which perform
cleaning actions.
The speed range of the beaters varies from
400-600 rpm.
3.Large cleaning chamber contains two drums
moving in the same direction of same diameter
of about 610mm.
4.Material from input comes in process with
drumbeaters, which is opened due to high
speed of the beaters.

34.  FINE CLEANER MACHINES CONSISTS OF
FOLLOWING MACHINES:
 1. RN CLEANER OF TRUTZSCHLER.
 2. UNIFLEX B 60 R OF RITER.
 3. HORIZONTAL OPENER B34 OF MORZOLI.

39.  THIS MACHINE FOR THE
OPENING , CLEANING , AND
DEDUSTING OF COTTON.

40.  1.FILLINE CHUTE.
 2.PERFORATED DRUM.
 3.DISTANCE BETWEEN
FEED THROUGH.
 4.GRID.
 5. OPENING CYLINDER.
 6.FAN.

41.  1.A fan draws the tufts by suction from the preceding machine and a distribution
element ejects them into a filling chute .
 2. The rear wall of the chute consists of individual aluminum lamellae with slot-
openings through which the air can escape.
 3.Thus a very homogeneous batting laydown is formed both lengthwise and
crosswise.
 4. The adjustable chute depth determines the lap weight required depending on
production and type of fiber.
 5. The material is carried further by a perforated drum and a plain drum.
 6. The machine is equipped with automatic lap intake, thus no manual
intervention is needed when starting up the fine cleaner.
 7.The distance between feed trough and opening cylinder is adapted by the
programming to the material being processed.
 8.The feed roll supplies the material to the opening cylinder.

42.  9.The opening cylinder, which is available in different
versions depending on the requirements of the material,
takes over the material. Using VarioSet, the spinner can set
the rotation speed of the opening cylinder according to his
objectives and raw material.
 10. A grid made of carding segments and knives forms
the cleaning surface and extracts impurities.
 11.The carding segments on the knives increase the
degree of opening and consequently the cleaning.
 12.The operator can, once again, use the VarioSet to
adjust the setting of the knives on the grid according to
his objectives and raw material.
