Problem:

A manufacturer of stainless food handling equipment was having a problem with product damage in the handling of Spanish-style peanuts. The stainless storage bin metered on to a belt at various rates depending on package size.

Situation:

The current solution was to hammer on the bin with a rubber mallet to induce heavier flow for larger packaging.

Solution:

The addition of a MARTIN® CD18—470 Vibrator (set back to the lowest setting) moves the product smoothly with minimal damage.

The manufacturer has since standardized on our products.

So much rides on the effectiveness of a electric vibrator. They are used to promote the flow of difficult bulk solids in many applications, including from bins, hoppers and silos. Vibrators promote the flow of material by overcoming the cohesive strength of the material and the friction between the material and bin wall within the cone section of the vessel. They are specifically designed to do this efficiently.

Martin Vibration Systems has been providing material flow-aids for many years and offer cost-effective solutions, expert technical assistance and complete service and support.

Problem:

A chemical plant was having a problem with material moving through a 60″ x 12″ chute with the help of a piston vibrator caused enough noise that “neighbors” complained. I realized that linear vibration would move the material, so the impacting, quiet.

Situation:

This company makes a variety of chemicals in small lots to test for mass production. Material size, consistency, and moisture content changed daily causing it to rathole and bridge in the dryer.

Solution:

The solution was to use an NTS 50/10 mounted on the dryer. This allows the customer to easily adjust the frequency and amplitude to meet changing demands. Also, the vibrator rotates with the dryer; therefore, the quick-connect air couplings increase efficiency.

Problem:

Large bulk materials are the hardest materials to move with flow aids. One plant was experiencing back up with their hog fuel and woods chips.

Situation:

A regional plant was experiencing back up and flow problems with their hog fuel and woods chips. BIG BLASTER® Air Cannons are the most effective in getting wood products to flow, however there was no plant air. The solution was an 1800 rpm MOTOMAGNETIC® Electric Vibrator.

Solution:

The customer had a flop gate, pant leg arrangement loading the material to an open truck. Because of the shallow angle there were frequent plugs which would back up into the disc screen. A CD18-1670 was mounted to a 1/2“plate with grade five bolts and a compression washer. The plate was welded solid to a 1/8″ X 6″ X 8′ channel. The channel was stitch welded without welding the corners.

The vibrator is operating at about 30% of its capacity and is wired to the motor control center. Overload is set at 1.0 amp/460 volts.

Electric vibrators solve material flow of bulk materials through any size bin, hopper or chute. They are virtually silent and are long lasting providing many years of service under the toughest conditions. Even though electric vibrators are more costly then pneumatic vibrators, they operate with nearly no maintenance costs and save your more money in the long run.

Compaction tables are used to compact, settle and combine material. The material is then put into a container in preparation for shipping.

Compaction tables are designed and fabricated to suit the specific needs of your application. Your table can be powered by pneumatic or electric vibrators, and a variety of control configurations are available.

Martin Vibration Systems and Solutions designs compaction tables with quality components and materials to provide a reliable piece of equipment that will prove to be successful for many years to come.

Problem:

An ostrich farm needed a faster method of removing waste from their numerous bird pens.

Situation:

Their prior method was to use a screen which had to be tilted and shaken by hand, on a 4′ X 8′ frame setting on a golf cart trailer for portability. The tires would act as a vibrator between the ground and the trailer.

Solution:

A model CDS36-390 was attached to the center of the reinforced screen frame secured to the trailer. The reclaimable material (mill) passes through the screen and can be re-spread after the trailer is removed. Each pen is equipped with 115/60/1HP outlets for simple plug-in operation. This operation must be performed daily and with the vibrator application. It is done by one person in approximately
one fourth of the time that it took before.

Problem:

A chocolate mint company in Wisconsin was having quality control problems. Their chocolate mints were not evenly stratified, layered from brown chocolate to green then to dark chocolate.

In addition they wanted to reduce the re-melt of the product, reduce extra chocolate that was used to compensate for uneven fill, reduce noise, reduce maintenance, be able to vary the output of the vibration, and get guaranteed results.

Situation:

The customer desired a clearly stratified candy, ie. layered from brown chocolate to green to dark chocolate. He wanted to solve the quality control problems by utilizing a MARTIN® vibration system to settle the candy as it was poured into trays.

They were using a low-frequency, low-amplitude rapper bar on their fill trays in their chocolate operation. Visualizing an ice cube tray would give you a good idea of how the candy is poured. The rapper bar was giving them inadequate settling of the material: therefore, the resulting appearance of the candies was not cleanly stratified as depicted in their advertisement. The customer wanted to correct this problem, so Martin Vibration Systems were contacted.

Solution:

The solution was the MARTIN® MOTOMAGNETIC® Electric Vibrator that addressed the following needs:

- promoted the flow within the mold cavity…the product would become more uniform, reducing re-melt and saving extra chocolate
- vibrators are quiet…by replacing the jolt tables with high—frequency energy, a substantial reduction in noise was realized
- the vibrators are engineered beyond industry standards and are guaranteed with an unconditional 3-year guarantee
- the MOTOMAGNETIC® Units offer a wide range of force by changing the settings on the eccentrics

The utilization of the CD-3600 electrics to corrected their problem. The application of MARTIN® Equipment has given them a product they can now feel proud of and advertise accordingly to fit their corporate image. It was a “sticky” situation that we corrected with a “sweet” solution.

Problem:

A North Carolina material stone quarry, was having a problem with their pug mill plugging up and shutting down production.

Situation:

The existing rotary electric vibrators that are installed on the pug mill were not sized properly which required them to operate at maximum output. This resulted in frequent motor failures and bearings to fail.

Solution:

Martin Vibration replaced their existing electric vibrators with two CD36-1660s, both of which were installed on the pug mill. Each vibrator was mounted to a 3/4″ thick mount plate which was solid welded to an”I“beam. In turn this “I“beam was stitch welded vertically to the opposite sides of the pug mill and wired to the motor control center. Great care was taken in mounting the vibrator to the mount plate. The results are the
output became smooth with no plugging or buildup which no longer required them to shut down production.
