Studying the influence of some parameters of opening and cleaning machines on cleaning efficiency

Abstract EN

The aim of this work is studying the influence of some parameters of blowroom opening and cleaning machines on cleaning efficiency.

Effect of grid gap width on waste and good fibre elimination as well as cleaning efficiency is studied for opening and cleaning machines and for blowroom line.

Factorial analysis were carried out to determine if the variation in cleaning efficiency is significant or by accident.

For bale opener the variables were cotton type (trash content), grid gap width and spiked lattice and evener roller setting with interaction 2 x 3 x 5.

Also for cleaner RN factorial analysis were carried out for grid gap width and feed roller speed with interaction 4 x 3.

Results showed that trash content and grid gap width as well as the other variables have a significantly effect on cleaning efficiency.

Every elimination of foreign matter is accompanied by a simultaneous elimination of good fibres.

For opening and cleaning machines, as grid gap width increased trash and good fibres eliminated increased, but the rate of good fibres elimination is higher than the rate of trash elimination.

For blowroom line increasing grid gap width of opening and cleaning machines from narrow to open level raised the cleaning efficiency from 43 % to 56 % and good fibres eliminated increased by 310 %.
