Principles of Spiral Gravity Classification
Resultthat depends on the magnitude of Do and the pitch. As an example if the cylinder diameter is 100mm, the formed spiral diameter is 500mm and a 45˚ inner slope is involved then the downward slope of the outer edge would be 11.3˚ (see fig.4, yellow angle). The formed spiral would also slope inwards towards the supporting cylinder.
