Modern Blow Room Line | The Installation as a Sequence of Blowroom Machines | Modern Blow Room Line for American

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:
