On the other hand, the high efficiency of a ball screw drive makes it more likely than a lead screw to back drive in a vertical application.But if the application requires a ball screw for positioning accuracy, load capacity, or rigidity, there is a way for designers to determine the likelihood that back driving will occur.
Calculate the inertia momentum from a ball mill.Any idea hello everybody i need to calculate the inertia momentum from my ball mill, in order to design the powersize of the mill start system.Could somebody help me best regards and thanks.
After a roll change or a mill stop rolls need some time to return to stable thermal conditions, every new bar entering the mill creates an impact,.And sometimes there are really severe rolling accidents, due to faults by operators, weak rolled materials with internal defects, or because.
