Study On Blow Room In The Ring Spinning

Experiments Name: Study On Blow Room In The Ring Spinning

Blow Room:
Blow room contributes only about 5 – 10 % to production cost in the ring spinning mill.
 
Object of Blow Room:
01.    To open the baled fiber into small tuff which allow foreign material to be separated from the fibers and prepare the material for easy carding.
02.    To clean the fibers by removing the foreign matters as the waste.
03.    To mix thoroughly the different component fibers of a mixing so as to give a homogeneous blending.

Basic parameter to be consider in blow room process:
01.    No of opening mc
02.    Type of beater
03.    Type of beating
04.    Beater speed
05.    Setting between feed roller  and beater
06.    Production rate  of the entire line
07.    Production rate of individual machine
08.    Density of the feed web
09.    Fiber in the feed
10.    Type of clothing of the beater
11.    Point density  of clothing
12.    Type of guide and guide setting
13.    Air flow through the mc in the sequence
14.    Amount of trash in the material
15.    Type of trash in the in the material
16.    Temperature and relative humidity in the blow room department

Working principle of Blendomat:
The Balandomet BDT 019 is required with two opening rolls . Depending on the direction of travel one roll is always working against the travel and one with the travel. This means that at one time the teeth opener roll works in the direction of travel of the of the machine and then in the opposite direction.
The roll which is operating in the opposite direction to the travel of the of the machine is raised by up to 10 mm by means of a motor. This the roll which is operating by a motor. This the roll which is operating in the same direction as the travel penetrates more deeply into the bale.

Working procedure of Axiflow cleaner:
This well proven cleaner can in particular case be used in addition to the CLEANOMAT machines. If that is to be considered as a first cleaning stage and is allow placed before the blenders and the fine cleaners the AXIFLOW AFC is particularly suitable for processing materials with a very amount of contamination cares trash particles are separated out and removed. A bucket wheel trap separates the cleaning section of the AxI-FLOW AFC from the waste suction system .It eliminates pressure variation in the machine and thus also fluctuation in the cleaning efficiency . then removal from the AXI FLO AFC can be either constant on intermittent.

Main parts of Axiflow cleaner:
01.    Inlet duct with guide plate 
02.    Cleaning rolls/Beaken
03.    Deflector plate
04.    Bucket wheel trap
05.    Waste separator
06.    Outlet duct with fresh air.

Working procedure of cleanomat:
The cleaning point of each spiked needle and saw toot roll consist of deflector blades, mote knives and suction hood. Trush particles released due to centrifugal forces and are separated at the mote knives and continuously taken away by suction hood. This ensure an optimum cleaning efficiency of the deflector blades in front of the  mote knives determine the degree of cleaning . With clean cottons or a low degree of cleaning the deflector blades are almost closed. If there are many trash particle to be removed and if a higher degree of cleaning is required the blades are opened further . Adjustment is by means of a motor.

Main parts of Cleanomat:
1)    Cleaning roll;
2)    Deflector blade;
3)    Mote knifes;
4)    Suction hood;

Write the working procedure of multiplex mixture :
A fan feeds the material into the miner . The individuals chambers are filled one after the other. The dust fade transport air escaper through perforated plates in the chamber and is then fed to a filter . the filling of the multiplier mean starts with the last chamber . All chamber s are  successively filled in several stages until one chamber reaches its minimum filled height . then the delivery rolls underneath each chamber are activated and the material is fed via the opening roll onto the conveyor belt. As the chambers empty , they are again filled one after another. A loss layer of tufts from the several chamber builds up on the  bleeding conveyor. At its end there are material layer from all chamber layer on top of each other . [From the web in directed fed into a clearer or an open]. This process o f filling mining and feeding a  cleaner are controlled and monitored by the integral control MXCOMMANDER.  Information on all designed operating data is shown on the display in selected languages.
Main parts of multiplex mixer:
01.    Feed funnel;
02.    Closing flop;
03.    Mixing chamber;
04.    Feed duct;
05.    Light barrier;
06.    Exhaust air funnel;
07.    Perforated plate;
08.    Delivering rolls;
09.    Opening rolls;
10.    Blending conveyor;
11.    Blending duct;
12.    Materials conveyor belt;
13.    Material suction funnel;
14.    Cleaner CLEANOMAT CVT


Advantages of Duster:
1.    Higher efficiency rates;
2.    Longer lives of clothes and spinning clement;
3.     Better running behavior of the spinning machine;
4.    Increased economic efficiency of the total installation;
5.    Clean ambient air.
