| Abstract: | Applications of flow aid devices (commonly referred as inserts) improve the silo
discharging mode. Considerable efforts have been made in finding best configurations
between the inserts and silos to achieve the optimal functional results. In the present
investigation, experiments were carried out to measure the loads imposed on a double
cone insert by the particulate solids (free flow sand) when it was fitted within an axisymmetrical
large scale silo. A concentric filling / discharging was implemented to fulfil
such measurements. Pressures developed along the walls of the silo were also measured.
Analyses of the measurement results showed that: 1.) the loads on insert were rather
stable in total, but appeared to be asymmetrical at the end filling; 2.) a sudden increase
was observed of the loads on the insert at the transition from filling to discharging, this
increase did not last soon afterward; 3.) such loads decreased slowly but remained rather
high for large part of discharge. Effects of the double cone insert on the pressures along
the silo walls were discussed. |
