Screw conveyor design calculation - an Engineering

2021-3-5  Few formula exist in the literature and are presented in this short Engineering Guide. Warning : It must be noted that those formula aim at giving an idea of the size of the screw conveyor (which means its diameter) and the speed at which it will operate, based on some assumptions and some design decisions (choice of screw pitch, inclination).

2021-2-21  The same approach is repeated for a 9 in screw conveyor. From the tables, a 6 in screw conveyor with a filling rate of 45% has 1270 ft3/h at 165 rpm and 8.20 ft3/h at 1 rpm. N = 346 * 1.2 * 1 * 1 * 1 / 8.20 = 50 rpm This time the required speed is clearly on the safe side vs the tabulated value.
