In theory combing, carding selection Licker member diameter size is very important, not only because of the size of the diameter of the impact area of ​​the machine case, and to sort out the effect is also important or even decisive influence
Most countries were taken licker diameter of about 250mm, but some countries stab reel diameter different. As Ma Zuoli company in the 1970s produced C40 carding machine, which licker diameter of 228mm, in the subsequent production of the C300, CX400, C501 is used licker 350mm diameter, it is the largest known carding machine. Poland CZ-690 uses a 236mm diameter licker size, the United States Hollingsworth using 229mm size, use Japan CK7C 208mm size, use of green machine 1182 over 200mm size, contemporary production from the carding machine with a minimum size is OK903 thorn reel type and FA225 carding machine, they are three-licker system, the three licker a diameter of 172.5mm, the smallest known carding machine.
Licker diameter sized influence on the following issues:
1) transfer of fiber carding and influential. Generally, when licker diameter is small, the speed is large, isolated, carding fibers better, but also conducive to fiber transport (especially when using the needle), which may be DK903, FA225 with small diameter licker reasons .
(2) the size of the denuded zone affected. A fake, a stab reel diameter, the denuded zone, is conducive denuded zone arrangements in favor of removing impurities such as Ma Zuoli C501 carding a larger diameter of 350mm its arrangements under the licker three groups with impurity suctions dust knife, two deflection blades, two carding plate, which is said to impurity effect is good, the area to be completed by 90% impurity work.
(3) impact of centrifugal force, in general, when the diameter licker hours, at the same linear velocity, the greater the centrifugal force, is conducive to the transfer of fibers and impurities removed.
