Case Study: Reduce Costs by Implementing An NTS Vibrator

Problem

A Michigan manufacturer was experiencing costly maintenance problems with their electric vibrators inside their wood fired power plant. These vibrators continuously caused damage to their screen deck and supports which in turn required costly rebuilds and repairs.

Situation

Their existing rotary electric vibrators were mounted on 4 x 6 ft screens, which were used to screen pyrites from the exhaust gases. They run at 3600 revolutions per minute and are mounted to an arm which tapped the screen deck. The manufacturer felt that speed was the problem, so they purchased a frequency inverter to control the RPMs. This helped some, but the maintenance cost to repair the vibrator, screen deck, and supports were still excessive.

Solution

Martin Vibration Systems recommended a NTS-50-04 Vibrator because of its versatility and the ability to independently control the frequency, amplitude, and forced output. With this new system, the force output requirement was only about one-half of the force they were using with the rotary vibrator.

Case Study: Eliminate Backup with an NTS Oscillator

Problem

Martin Vibration Systems supplied stainless steel woven wire belts to a Detroit chemical plant. This belt handles small catalytic pellets, when exiting the furnace they are dry and brittle and fall through the weave on the wire belt and build up on the head pulley causing the belt to mistrack.

Situation

Initially the pellets are wet and fed into the furnace to dry out. After these pellets come out of the furnace and the moisture is removed they become hard and brittle and often break during handling. The problem occurs when these pellets break. As these pellets crumble, the fines and dust fall between the weave on the wire belt and build up on the head pulley causing the belt to mistrack.

Solution

Upon inspection of the belt, we determined by tapping the belt how easily the fines and dust fell to the floor. Martin Vibration Systems recommended a NTS-5 Oscillator to tap on the belt. An additional benefit of this vibrating belt cleaner is that since the cleaner is 43 & 1/2 inches wide and the belt is 46 & 1/2 inches inside the edges, our cleaner also helps train the belt. Our customer is very pleased with the results of this innovative Martin solution to a material handling problem.

Case Study: Chute Build Up – NTS 54/02 Vibrator

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.

Case Study: Rotary Electric Vibrator Solution

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.

Case Study: Filling Tank Trucks – NTS 50/40 with a VAC-MOUNT™ 20

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.

Case Study: Air Consumption Reduced With NTS 50/04 Linear Vibrator

Problem

An Arkansas gypsum plant manager became concerned about air consumption. They saw that they would need to reduce the load on the plant air system or be forced to upgrade to a larger compressor.

Situation

The plant, for many years had used a VIBROLLER^® UCVR 6-.5 Vibrator installed underneath the mixer belt to vibrate and form the gypsum slurry. This roller vibrator did a good job of consolidating the material, and so periodically as needed, the plant would just replace a worn-out vibrator with a new one.

Solution

To demonstrate, the NTS 50/04 Linear Vibrator was placed on a VAC-MOUNT™ Portable Mount. At 60 psi, the NTS 50/04 Vibrator is rated at 10 cfm–less than half of the VIBROLLER^® Vibrator’s 21 cfm air consumption.

With the VAC-MOUNT™ Portable Vibrator applied temporarily underneath the mixer belt, the plant could see its effective vibration. As a result, they bought an NTS 50/04 and permanently installed it to replace the roller vibrator.

The NTS 50/40 did better job of consolidation, with quieter operations. And most importantly, they are using less air, reducing energy consumption, and avoiding the purchase of a larger air compressor.

Case Study: Sticky Situation Resolved With An NTS Vibrator

Problem

A Michigan packaging company was having problems getting wood chips to discharge from storage bins.

Situation

Customer was having problems getting wood chips to discharge from a storage container into a screw conveyor. Due to excess moisture and extremely cold temperatures during the winter, the wood chips were bridging. They were using two men with sledge hammers to regain flow.

Solution

Martin Vaibration Systems mounted two NTS 50/04 and two NTS 50/02vinrators in different locations. The low air consumption, non-impacting and quiet features of these NTS Vibrators were benefits the customer really liked.

Case Study: Successful Lime Compaction Using NTS 50/04

Problem

A lime processing plant in Brazil was having a problem load lime into tank trucks. The lime was not filling the tank completely therefore wasting a lot of space.

Situation

To fill the trucks, they drove them around the factory three times for material compaction. They realized that this process of stopping to fill the trucks, driving them around and then fill again was not the most efficient method.

Solution

To improve the loading process, Martin Do Brazil installed one NTS 50/04 with a VAC-MOUNT™ 20 on the trucks.

Now this customer fills the tank trucks in a third of the time it previously took and without the trucks “racing” around. They used to fill each truck with 26 tons of material, and now they fill them with 27 tons of material. Cimento Itau is very impressed with this improvement.

Case Study: NTS 50/10 Solves Material Flow Problem

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.

Case Study: Non-Impacting Vibrator Eliminates Limestone Buildup

Problem

A Michigan manufacturer was experiencing a buildup of limestone fines on the bottom slope section of their screens. This buildup caused the bottom screen to blind which would then cause the next screen to blind, and so on until every screen deck was blinded to the top.

Situation

If the conveyor feeding the screen was not shut down in time tons of material would spill and overflow. Then production would come to a halt. They would have to hammer out the buildup, which would take hours and therefore costs would be passed on to the consumer.

Solution

Our solution was to mount a non-impacting vibrator to the sloped section of the screen to remove the fines. The NTS 54/02 with VAC 20 Mount was assembled to test. We let the unit run for one hour. The results no fines build up, no blinding of the screens and no loss of production.

Case Study: NTS Vibrators Loosen Wood Bridges

Problem

A manufacturer in Midland, MI uses a wood-burning powerhouse for their plant. The problems they were having was the wood was forming bridges inside their five feeders.

Situation

They tried using vibrators to shake the wood bridges loose but only had minimal success. Operators had to take time to loosen the bridges.

Solution

Our solution was to mount several NTS 50/04 vibrators. The vibrators wereset up a timer system to supply air every minute for 15 seconds to each vibrator. This has solved their bridging problem. Therefore, wood gets to their belts and the operators are free to work in other areas of the plant.

Case Study: Automotive Plant Has Issues With Buildup

Problem

An automotive assembly plant in Detroit, Michigan utilizes their own coal- fired utility. The company has experienced build up on a number of chutes in their fuel-handling system. As a result, air lances and shovels must be used daily to clean the build-up to avoid ongoing problems. Unfortunately, dealing with this issue meant that operators had less time to focus on other areas of the plant. Additionally, fly ash hoppers were bridging. The vibrators being used were not effective in providing enough vibration or were simply malfunctioning altogether.

Situation

Martin Vibration Systems did two things. First, we sold the plant an NTS 54/02 on a VAC 20 MOUNT. Second, we recommended NTS Vibrators with FRL units. The company purchased an NTS 50/01 and an NTS 54/02.

Solution

The portable unit has resolved the issue of buildup, which effectively allows the operators more time to spend in other areas of the plant. Additionally, the new NTS units will be evaluated to determine which offers superior performance. The best of the two will be selected for their 23 ash hoppers.
