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 rubber rollers with different hardness have different grinding cycles, and the rubber rollers with the same hardness have different life cycles. (See table below).

In addition, the gap between the cores of the rubber roller can be adjusted to the rear drive.

If the gap between the front rubber roller bearings is too large, the impact 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 impact is small, and the impact on the spinning quality is particularly small.
