Trützschler blow room line:
Trützschler blow room lines are always made-to-measure. Whether processing man-made fibers, a few hundred or several thousand kilos per hour, Trützschler offers an efficient solution for every application. The main principle of Trutzschler blow room machines is to open the material and reduce it to the smallest possible tuft size and cleaning the raw materials. A flowchart of trutzschler blowroom line is as follows;

Basic Operations Involved in Blowroom
The basic operations can be categorized into 4 sections. Take a look at them –
- Fiber Opening: Opening the compacted bales into small flocks. Then converting the cotton flocks into as tiny as possible. Flocks or the tufts weight is condensed to roughly 0.1 mg.
- Fiber Cleaning: Elimination of dust, fragmented seeds, dry leaves, stems, and other external ingredients from the fibers.
- Fiber Mixing or Blending: Same or different grades of fibers get mixed and blended all together to manufacture quality yarn and lessen the raw material cost.
- Lap: Transferring the opened up and cleaned flocks into a thin sheet form called a lap. It has a fixed width and constant length. Blow room needs to make sure that raw materials fed to the card are even. This is implemented through the precise wt. of laps collected from the scratcher.
Operating Zones in the Blowroom
| Operating Zones | Functions |
| 01. Gradual Opening | Gradually opening the fibers out of the bales into small tufts. |
| 02. Extensive Cleaning | Cleaning the trash particles (unit size beyond 500 µm) |
| 03. Blending or Mixing | Mixing homogeneously or blending the fiber evenly. |
| 04. Fine Cleaning | Eliminating macro-dust (unit size 50- 500 µm) |
| 05. Intensive Cleaning | Eliminating micro dust (unit size 15- 50 µm) |
| 06. Lap or Chute feeding to the card | Even lap or chute feed to the card |
