The grinding cycle of roving and spun rubber rollers is mainly determined according to the hardness, usage time and output of roving and spinning rubber rollers. The hardness of different rubber rollers is different, and the life of rubber rollers with the same hardness is different. (See table below).
In addition, the gap between the roller cores can be adjusted to the rear drive.
If the gap between the front rubber roller bearings is too large, the effect on the strip CV value is between 0.1% and 0.6%; if the gap between the rear or middle rubber roller bearings is too large, the The impact is between 0.01% and 0.1%. Therefore, when the rubber roller bearing gap is large, it is generally used for the rear rubber roller. Because the running speed of the rear rubber roller is low, the influence is small, and the influence on the spinning quality is particularly small.
