A spring assembly includes a resilient member having a first and second end shanks and a central helical portion. The first end shank extends in a first direction from the central helical portion, and has a longitudinal axis from a proximal end to a distal end. The second end shank extends in a second, opposite direction from the central helical portion, and has a longitudinal axis from a proximal end to a distal end. The central helical portion includes one or more coils disposed about a central longitudinal axis, and has a first end attached to the proximal end of the first end shank and a second end attached to the proximal end of the second end shank. The axes of the shank ends and the axis of the central helical portion are parallel or are collinear. The assembly also includes an attachment site at each of the end shanks.

A storage and reclaim system for bulk material includes a bulk material holding space having a bottom portion provided with a discharge port. The bottom portion includes an inclined support plate for supporting the bulk material and for assisting gravity induced feeding of the bulk material towards the discharge port. The support plate is supported by a support structure in a free-floating manner. One or more vibrators are connected to the support plate and configured to transfer vibrational energy to the support plate to induce a vibrational movement of the support plate. The discharge port includes one or more inclined discharge port plates. One or more vibrators are connected to each discharge port plate.

To provide an operation control method capable of securely reducing the required motor capacity and power consumption, a threshold based on the load size is preset, and after the driven/rotated state of two rotating shafts becomes steady, and if the load size is smaller than the threshold, the conveyance of rotating drive to one of the two rotating shafts is stopped and the rotating shaft with the conveyance of rotating drive stopped is rotated together interlocked with the other rotating shaft by vibration generated by the rotating drive of the other rotating shaft, and if the load size becomes larger than the threshold, the conveyance of rotating drive to the rotating shaft with the conveyance of rotating drive stopped is started so as to drive/rotate the two rotating shafts.

A vibratory apparatus includes a trough assembly, an exciter assembly and first and second toroidal members. The trough assembly includes a trough and first and second walls attached to the trough with a space disposed therebetween. The exciter assembly includes a central mount with first and second opposite sides and first and second opposite ends, and first and second eccentric assemblies each including at least one motor having a shaft with a shaft axis and at least one eccentric attached to the shaft for rotation about the shaft axis, the first eccentric assembly attached to the first end and the second eccentric assembly attached to the second end. The first toroidal resilient member is disposed between the first wall and the first side and the second toroidal resilient member is disposed between the second wall and the second side, with the exciter assembly disposed in the space.
