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-MOUNTâ„¢ 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.

How does the pharmaceutical industry benefit from Martin’s Vibratory Feeders? Most vibrators operate lubrication-free and Teflon coated. The state-of-the-art designs insure energy-efficiency and long life. Pharmaceutical feeders flow into bucket elevators, onto belt conveyors, feeding weigh scales, packaging equipment or metering product from bins or hoppers to name just some of the more common applications. Conveying by vibration provides a smooth product transfer with no pharmaceutical product degradation.

Problem:

Dow Corning of Midland, Michigan, was experiencing high maintenance problems with electric vibrators in their wood-fired power plant. These rotary electric vibrators were mounted on 4-ft x 6-ft screens, which were used to screen pyrites from the exhaust gases. These vibrators, which run at 3600 revolutions per minute, were mounted to an arm that tapped the screen deck. This type of vibration caused damage to the screen deck and supports. The customer felt that speed was the problem, so he purchased a frequency inverted to control the RPMs. This helped some, but the maintenance cost to repair the vibrator, screen deck, and supports was still excessive.

Situation:

The customer called his local Martin salesperson for assistance in solving this vibration problem. He recommended an NTS-50-04 Bin Vibrator as the solution. The NTS Electric Bin Vibrator was chosen because of its versatility. Having the ability to independently control the frequency, amplitude, and force output was key in solving this problem. After installation, the vibrator was fine tuned to the exact force to do the job.

Solution:

We found the force output requirement was only about one-half of the force they were using with the rotary vibrator. Before changing to the NTS vibrator, the customer had to rebuild his screen every l8-24 months. He has now had the NTS for over two years, and there has been no damage to the screen deck or supports.

Problem:

An automobile assembly plant in Detroit Michigan was experiencing build up on the chute walls in their fuel handling system.

Situation:

This assembly plant has their own coal-fired utility. Some of the chutes in their fuel-handling system plug up from buildup on the chute walls over a period of time. To prevent this from happening operators constantly use air lances and shovels to clean the buildup daily. This took a lot of the operators’ time away from further improvements or maintenance areas in the plant.

Solution:

We introduced the NTS 54/02 on a VAC 20 MOUNT, a portable unit that takes care of the buildup and gives the operators more time to work in other areas.

There are several reasons why a concrete vibrator is important.. Concrete vibrators are not used only to consolidate the concrete for maximum density, but they also internally blend the different lifts of concrete together into a single solid mass with few to no air pockets and no lift lines on the finished exposed surface. Improper consolidation of concrete can cause product defects, compromise the concrete strength, and produce surface blemishes such as bug holes and honeycombing.

Concrete vibrators range in size from small battery-powered to much larger plug-in versions that be used on very deep pours. A concrete vibrator should reach the bottom of the pouring forms to ensure an even treatment of the entire concrete pour. Attachments for the concrete vibrator are selected on the basis of the depth of the pour and the type of concrete being used. The goal in using a concrete vibrator is to build a strong matrix of material that will withstand years of use.

Vibrating tables are often critical components of production and industrial flow systems. Hoppers, bins, feeders, and packaging systems can all benefit from vibration.

1. Improve product flow and consistency. Vibration breaks the friction between materials and allows them to flow freely. This benefit will save money by reducing product loss caused by build up in hopper, clogging or jams in line, overspill and other material flow problems.

2. Safer Work Environment. Martin Vibrators are less noisy as traditional industrial vibrators. Most operate below OSHA noise standards therefore reducing hearing damage. Since vibrators eliminate clogs in bins and hoppers, employees are not at risk clearing these clogs.

3. Improves Packaging. Vibration compacts bagged material, therefore more tight fitting bagged material for shipping.

4. Improves production time and lowers labor costs. No more wasted labor hours. Time spent cleaning and unclogging will now be used toward more productive, value added tasks.

5. Eliminate waste. Martin vibrations systems helps to eliminate waste in most material flow systems by reducing clogs and waste by improving accuracy, consistency and quality of your material flow systems.

Getting bulk material to flow readily can be a costly challenge. In some applications, bulk powder, granular material and liquids are combined to create a thick slurry. Getting this thick slurry to flow consistently depends on the angle of your discharge and the thickness of your mixture.

One example of potential flow problem is with concrete. Most problems with concrete occur when the concrete is discharged from the mix trucks. Two common problems with concrete flow is the strength of the mixture and the friction between the mixture and the material it flows thru.

To ensure a smooth flow, an industrial vibrator is used. Industrial vibrators produce several pounds of force into the material to promote and maintain a constant concrete flow. An efficient and effective vibrator is the MARTIN® WHIRLWIND™ High-Frequency Turbine Vibrator. It produces more power with less noise than any other high-force/high-frequency pneumatic turbine vibrator. Units mount easily to cradle lug brackets or rail car wedge brackets, and operate quietly to meet OSHA noise requirements.

Problem:

A large bakery in Atlanta Georgia shipped in bulk broken cookie pieces to be used in cookies & cream ice cream. The cookies are cooked whole, broken, and fed by conveyor into boxes that are lined with a plastic bag. The process is continuous, and the operator was often left shaking the boxes to level the cookies and remove air pockets that developed between the box and the plastic.
.

Situation:

Shaking the boxes and leveling product slows production and decreases speed and daily output. In addition, the repetitive shaking of boxes caused complaints of fatigue from the operators that resulted in shifting personnel from one task to another, further slowing production. Rather than shaking the entire box conveyor as requested by our customer, we approached this problem with an NTK-25 vibrator mounted as shown on the attached sketch.

Solution:

Martin Vibration Systems fabricated an assembly to attach to the underside of the live roller conveyor, piped the vibrator to be activated by foot pedal at the operations station, and included a rubber pad on the piston end of the vibrator to be used as a “strike plate”. When activated, the NTK-25 taps the box (similar to the shaking procedure used by the operator), levels the cookies, and helps dissipate the air pockets. This one vibrator increased output, reduced employee complaints and eliminated the need for additional controls and conveyor modification.
