  3. 3. INTRODUCTION OF MORDERN BLOWROOM In processing the material, different types of machines are necessary, namely those suitable for opening, those for cleaning and those for blending. There are no universal machines, and a blowroom line is a sequence of different machines arranged in series and connected by transport ducts. In its own position in the line, each machine gives optimum performance – at any other position it gives less than its optimum. Finally, the assembly of a blowroom line depends among other things on: 1.The type of raw material; 2The characteristics of the raw material; 3.Waste content; 4.Dirt content; 5.Material throughput; On the basis of these cases ,there are some modern blowroom lines.From these blowroom lines, we are going to present the Rieter Blowroom line.

  11. 11. Features and functions of UNIclean B 12 The UNIclean is designed for output of up to 1 400 kg/h (carded sliver). Fibre yield with simultaneous efficient cleaning is up to 2% higher than on conventional units. Energy-saving due to low air consumption. Pre-cleaning without nipping and the use of mote knives results in fibre-preserving cleaning. The large dedusting surface ensures intensive dedusting even at high production performance. Rapid assessment of high cleaning performance and low losses of good fibers by visual waste checks.

  15. 15. Features and functions of UNImix B 75 The production volume of 1200 kg/h (B 76) results in an excellent price/performance ratio with comparably low space requirements. The large storage capacity ensures regular feeding of the downstream blowroom machines and is the precondition for the production of quality yarn without personnel intervention. Bypass facility for the cleaner module (e.g. with man-made fibers) for rapid mix change. The unique 3-point mixing principle with 8 mixing chambers produces a good, permanently homogeneous fibre mix. optimal opening and homogeneous feed to the subsequent process are thus guaranteed. Integrated dust removal separates the dust-laden conveying air from the fiber material. This occurs extremely gently and consequently improves the running behavior of the spinning machine and thus also yarn quality

  18. 18. Features and functions of 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.
  19. 19. 5. Condenser A 21
  20. 20. Features and functions of Condenser A 21 Almost all manufacturers of blowroom machines, and several others, now offer recycling installations. Primary waste is pneumatically fed via condensers into the B 34 mixing opener, pre-cleaned in the UNIclean B 12, dedusted in the A 21 condenser and cleaned further in the B 51R fine cleaner. The transport air is always separated from material and fed to the pre-filter.The yield of good fibers is fed into the bale press. Since the same types of machines are used in this recycling installation as in the blowroom, handling is easy for the operators. Secondary waste from the recycling machines and pre-filter is fed into the bale press for black waste. Since the same types of machines are used in this recycling installation as in the blowroom, handling is easy for the operators.

  22. 22. Features and functions of Card C 60 Maximum raw material utilization at carding output of up to 240 kg/h. The modular machine design reduces maintenancerelated 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
