Topic 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

 Rolls with teeth  Supporting rolls with teeth  Greed's beside the rolls  Leaver’s are connected with inversion mechanism.  One suction zone where the tuft cotton are thrown. Blendomat Blendomat is a system in which, the bale is opened by tufting. It contains-

Working Principle

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.

11 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 14

Uniclean / Pre cleaning Since removing finer trash particles is difficult, seeds and bigger trash particles should not be broken. Due to treat this 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. Features and functions of UNIstore A 78

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 Features and functions of Card C 60
