Control of end breakage rate is the prime requirement for getting better ring frame performance and for achieving higher spindle speed, points out N Balasubramanian, who suggests an improved method of testing significance of end breakage by any action without being influenced by day-to-day fluctuations.. Control of end breakage rate at ring frame is the first step for improving ring frame

The Cause of Rolling Mill Rolls Breakage Hani Tech

The Cause of Rolling Mill Rolls Breakage Author : hani Time : 2019/06/21. The rolls of rolling mill may break in practical application. According to the analysis of fracture phenomena, the main part of fracture is mainly concentrated in the roll ring, and the fracture section is irregularly inclined or a vertical section. So why does this happen?

Crushing Mechanism for Soil Particles

Typically, soil samples must be crushed into particles for laboratory research. Thus, an efficient mechanism to ensure a uniform particle size is essential. We previously developed a rod mill device that performs well, but video analysis indicated that the shear forces applied by the rod were more effective than the compressive forces applied by the mill.

2020-11-24  A major factor which limits the maximum spindle speed is the end breakage rate. An end break occurs whenever the spinning tension exceeds the yarn breaking force. End breakage rates of yarn produced from Giza 80 with various spindle speeds is given in Table 3. The data showed no effect of spindle speed on end breakage of 100 spindle/hour.
