1. Working principle of CL-C3: In this zone, basic function is to open the
fiber tuft to smallest size and to clean the tuft to the greater extent
removing even smallest size of trash and dust which are trapped
between fibers.
The system comprises 3 rotating beaters with carding saw tooth wire
projecting from its surface with different gradual point density and a
series of grid bars positioned below the beater. The system is used as a
last opening and cleaning stage for cotton tufts in the blow room and
therefore receives tufts from the coarse cleaner and opener.
Importantly, the beater speed should progressively increase from beater
1 to 3 (for example 900, 1100, 1400 rpm). Hence, the mean tuft size is
decreased from 1 mg by the first beater to 0.7 mg, 0.5 mg by the second
and third beater.
