Modern Blowroom

In processing the material, different types of machines are necessary, namely those suitable for  opening, those for  cleaning and those for  blending. Different intensities of processing are also required, because the tufts continually become smaller as they pass from stage to stage. Accordingly, while a coarsely clothed cleaning assembly is ideal after the bale opener, for example, it is inappropriate at the end of the line. Therefore, 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. Also there may be advantages in different modes of transport, feeding, processing, cleaning and so on from one machine to another along the line. 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;

the number of different origins of the material in a given blend.

In most cases a modern blowroom line consists of the following machines, as shown in Fig. 8 (Rieter) and Fig. 9 (Trützschler), illustrating two typical blowroom lines.
