INDUSTRIAL VIBRATOR RANGE

VIBRAMOTORS

Vibrators may be sized on the basis of the average weight of the material (lbs./kilos) in the slope portion of the bin or hopper. Select one or more of the vibrators nearest the actual amount of material.

The above chart is a reasonably accurate approach offering a quick vibrator selection on a bulk material weighing up to 100 lbs. per cu. ft. Consideration to other characteristics may be advisable.

Vibrators suggested on the above chart are selected at heavy duty working ratings which is approximately 50% of their maximum capacity. For optimum material flow adjust the pressure on air vibrators with an air regulator; hydraulic vibrators with a flow control and on electric vibrators manually adjust the unbalanced weights. Consult Linemann Customer Service Department for additional assistance.

1. CONICAL HOPPERS:

The vibrator should be mounted to a channel-iron stiffener at least 4'-8' long; although it is preferable that the channel iron extends the full extent of the slope portion of the hopper. If an existing horizontal stiffener is in the way, cut and reweld to the new vertical channel iron. The mounting base, vibrator and structure should be rigid. Locate the vibrator approximately 1/4 to 1/3 the distance from the discharge to the top of the slope portion of the hopper.

2. RECTANGULAR HOPPERS:

Mounting is the same as described above for conical hoppers. The channel iron should run vertical down the centre line of the slope face of one side. When using a second vibrator mount diametrically opposite and approximately 1/2 up the slope wall.

3. RECTANGULAR BINS WITH HOPPER BOTTOMS:

Follow the same mounting procedures as described above. However additional consideration should be given to the loading caused by the material above the hopper or sloped portion. Two or more vibrators will be more effective and distribute their energy more uniformly throughout the hopper to assure evacuation.

4. PARABOLIC BINS OR HOPPERS:

Mount a vibrator within one foot of each discharge in line with the centre of the discharge opening. The rotation of the vibrator should be in the same direction as the material flow.

5. BINS WITH SLOPING DISCHARGE CHUTE:

Mount the vibrator on the side that it is continuous with the underside of the chute The channel iron will provide rigidity to transmit the vibrator energy to include the. discharge at the throat of the chute.

6. BIN OR HOPPER WITH VERTICAL SIDE:

Install a channel iron as described above on the slope portion of the hopper. Mount the vibrator approximately 1/3 the distance from the departure point of the material. In most instances it is only necessary to operate the vibrator during short run cycles to draw the necessary material. Be sure to open the gate so as not to compact the material.

The use of channel stiffners will promote maximum transmission of vibration to the material held in bins, chutes or flow pipes. A rigid structure will eliminate "oil-canning" and eventually cracking of the hopper walls. Select a channel as long as possible and skip weld channels to the hopper walls as illustrated.

Skip or stitch-weld by welding 3", skip 1 weld 3", etc. Do not weld last 1 " of either end of channel or any corner. We suggest welding another piece of the same channel slightly larger than the base of the vibrator selected on the long channel for easy installation of the unit or: notching the long channel is permissible for access to the mounting bolts. See sketch figure 2 When additional width is required use a 3/4" steel plate welded to the channel as indicated in the drawing figure 3 (Do not mount the channel horizontally).

Single Vibrator Mounting. Mount vibrator on channel iron one third from the departure point of material of the tapered section. See figure 4 Multiple Vibrators. When the force is beyond the capabilities of the largest size vibrator listed-consider using 2 or more vibrators whose combined ratings equal or exceed the required force necessary to move the material. Also when the hopper diameter or longest side is greater than 12ft. consider using 2 or more vibrators.

SELECTION FOR CHUTES AND FLOW PIPES Calculate the total weight of the chute or flow pipe and the material within. Select vibrators with a force output of 3 times the total weight of the chute or flow pipe including the weight of the material and the vibrator. SELECTION FOR VESSEL SHAKEOUTS Calculate the total weight of the vessel and material build up to be removed. Select a vibrator with a force output of up to 3 times the total weight.
