Abstract :
Blockage is a common problem in many practical silo applications, and vibration seems to
be a practical solution to overcome this problem. An experimental setup was developed to
observe the effects of different vibrational parameters on vibrator anti-jamming efficiency.
The silo was made of transparent plates to provide the possibility of watching the materials
inside it. The outlet mass was recorded on a computer via a weighing load cell. The vibrator
was installed at different locations on the silo walls to reveal effects of the vibrator position
on its efficiency to prevent jamming. Moreover, relevant tests were conducted to reveal
the effects of the vibration frequency. A vibrometer instrument with contacting probe was
employed to measure the local vibration characteristics. The measured data was used to
identify the vibration dimensionless acceleration. It was concluded that the location of
the vibrator significantly affects its anti-jamming ability. Furthermore, it was observed
that the vibration frequency and acceleration influence the impact of the vibration to
prevent the silo jamming to some extent. It was observed that while the vibration does
not influence the instant discharge rate it does considerably affects the average rate.
