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.

Millions of workers are exposed to potentially damaging nois in the workplace each year. According to the National Institute for Occupational Safety and Health, about 30,000,000 US workers are affected.

One way to tackle the noise problem is to replace old vibrators with Martin Vibrations System’s pneumatic turbine vibrators. Our silent turbine vibrators may have a higher initial price than ball and piston vibrators, but cost less in the long run to operate and maintain.

Our vibrators eliminate or reduce noise, reduce the need for constant worker monitoring, and operate well below the threshold for sound under the Hearing Conservation Amendment.

Problem:

A large blending plant in Illinois was experiencing difficulty filling their large bagging machine.

Situation:

As the bagging machines filled, hopper levels were visually checked with a slight glass. Oftentimes, flour would plug these sight glasses resulting in lost production.

Solution:

An NTK-8 was super-glued to the sight glass. This small amount of vibration kept the glass clear with no damage to the glass.

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.

It is common for material flow problems to occur in bins, hoppers, and silos. Many of these problems are caused by a high level of friction between the material and the bin wall, and high cohesive strength within the material. When examining wall friction take into account the wall angle, wall material, smoothness, temperature, moisture, corrosion, abrasive wear, and the time the material remains at rest in the cone where the problem exists. Also the cohesiveness is affected by material properties, including moisture content.

When material flow problems occur solving these problems is essential for efficient production and accurate material inventory management. The key to solving these problems is to employ an industrial electric vibrator. Electric bin vibrators are used to break the friction between wall and material, as well as material cohesiveness, to promote material flow from the bin.

Industrial vibrators when properly selected offer an effective and high value solution. Martin Vibration Systems can provide with that solution. We offer many designs in vibration technology to fit your unique situation.

Problem:

A large manufacturer of metal shelving was experiencing a parts flow problem on a sheet metal press. The parts being stamped were plugging the die which caused frequent quality problems and “die” damage.

Situation:

A temporary solution was to have a worker stand on the other side of the press and manually pull hung-up parts with a hook, a tedious, costly, and potentially dangerous solution.

Solution:

Martin Vibration designed a vibrating chute using two CD18-70 electric vibrators. Parts now flow without trouble.

Since using our vibrators, the manufacturer has been able to increase production and move their worker to a much more needed and productive role.

Problem:

A Brazilian customer was having trouble loading lime into tank trucks. Material was not flowing into the trucks and fill completely without air pockets or gaps.

Situation:

They tried to solve the problem by driving the filled trucks around the factory three times for the material to compact. Finally realizing, that this process of stopping to fill the trucks, driving them around and then fill again was not the most efficient method

Solution:

To solve the problem, Martin Vibration installed their NTS 50/40 with a VAC-MOUNT™ 20 on the trucks.

The result is they can fill their tank trucks in a third of the time it previously took and without driving around. Their trucks used to be filled with 26 tons of material, now they are pouring 27 tons. This method is more productive and time efficient.

Nissan Canada Inc. introduced a new line of fork lift trucks featuring an innovative “floating cab” designed to eliminate vibration and reduce driver fatigue.

Situation

Drummond Equipment, Inc. was asked to supply mechanical equipment to simulate the vibration frequency and amplitude generated by a running lift truck so the benefits of the “floating cab” could be demonstrated at an indoor materials handling show.

Solution

Under our direction, the motor was removed and replaced with an NTK-110 with 50 lb. weight on a mount bracket of our design. In addition to the NTK—11O and mount bracket, the customer also purchased the air line accessories required to complete the equipment package.
