1. Saw blade drum speed
The saw blade drum speed is one of the important factors that determine the productivity of the stripping machine. The relationship between saw blade drum speed, lint stripping machine productivity and cotton lint yield is shown in Table 9-2. The relationship between the rotation speed of the saw blade drum and the lint yield, the impurity content of short lint and the broken cotton seed rate are shown in Table 9-3 and Table 9-4.
It can be seen from the data in Table 9-2 ~ Table 9-4 that increasing the speed of the saw blade drum , although the productivity of the stripping machine can be improved, the impurity content of short lint and the broken cotton rate will increase accordingly, and there is a certain linear relationship, which shows that the impurity content of short lint and the broken rate of cotton are related. . Therefore, the rotational speed of the saw blade drum must be properly selected on the premise that it is conducive to improving productivity without affecting the quality of the short pile. According to domestic and foreign data, the rotation speed of the saw blade drum with a diameter of 320mm is 700-730r/min, and the linear speed is 11.73-12.23m/s.
