Vibratory Discharge Chute Design

[ChinthakaF]

I am designing a vibratory discharge chute to transfer wood chips (of uneven sizes) from the discharge end of a conveyor in to an existing feed hopper attached to a boiler.



The chute (open on top) is 4 Ft. Long, 6 Ft. Wide and inclined at 30 Degrees to the horizontal.



Having discovered that the 30 Deg. incline was insufficient to transfer the wood chips by gravity I have to now modify the chute to attach a vibrating motor and appropriate support structure.



In this regard I need advise as to how I should select Springs and Rubber dampers (Simple Rubber blocks to keep cost low), to ensure vibration is isolated to the chute and does not affect the rest of the structure.



The chute with a full load and frame mounting weigh approx. 150 kg.



The motor specifications are as follows;

0.2 kW running at 2850 rpm.

Vibration Force = 260 kg

Vibration amplitude is adjustable by tuning the eccentric load on the motor.



General layout of the chute design is attached to this post.



I would really appreciate any help, comments or suggestions with this regard as I am new to materials handling.



Thank you.
