Abstract
The purpose of this investigation is to determine the available equations for design of table feeder. Taking note of the piled-out length M, the discharge-rate equation has been derived theoretically as Eq. (11). The calculated results of the discharge rate are in good agreement with the observed data as illustrated in Figs. 9∼11.
It has been observed that the value of M decreases as the insertion length of scraper increases, but finally M becomes constant value Mc at a critical distance between the scraper and the discharge pipe sc. These values of Mc and sc can be determined by Eqs. (9) and (6), respectively. Assuming M≥Mc, the empirical equations on M have been obtained as Eqs. (2) and (3).
The equations reported here may be actually available when the discharge rate is predicted from the operating conditions.
