Problem:
A local chemical plant handles small catalytic pellets that are wet when they are fed onto the belt and run through a furnace where they are dried out. After being dried out, the pellets become hard and brittle and break during handling which cause build up of debris causing the belt to mistrack.
Situation:
After the pellets are dried out they become hard and brittle and break during handling. The problem occurs when these pellets break, the fines and dust fall between the weave on the wire belt and build up causing the belt to mistrack.
Solution:
From tapping on the underside of the belt and noticing how easily the build falls loose, Martin Vibration Systems recommended mounting a NTK-5 Oscillator under the belt to provide the tapping action. The NTK-5 was mounted in such a way that the tapping affect would be transmitted along the belt’s entire width.

Problem:
A maintenance manager of a mushroom farm in Illinois approached us with a problem with their slicing mechanism. The operation produces in excess of 24 million pounds of mushrooms per year. These are the white and brown “button” mushrooms you can find in any supermarket. They are packaged both whole and sliced.
Situation:
Their slicing operation was causing problems because the mushrooms are sliced into thin strips by an automatic machine and there was no way to separate the very small pieces from the usable slices. They needed to find a way to separate the strips from the undersized parts.
Solution:
The finished product is essentially a screening unit made of Teflon-coated stainless steel with 5/8″ diameter perforations. The screen, powered by an NTK-40 with a two-pound weight attached is mounted on fiberglass springs and sits about 40″ off the floor on an epoxy-painted steel base. A stainless steel can placed underneath catches the undersize pieces.

Problem:
An Indiana chewing tobacco manufacturer was having quality and quantity problems with a particular product, ground tobacco contained in a small paper pouch, commonly referred to as chew or snuff.
Situation:
The problem was that as the automated machinery dropped the desired 20 pouches into a small cylindrical plastic can, the pouches would lay on the edge of the can. when the lid was put on, the pouches would be squashed, half in and half out of the container. This would obviously cause a rejected can. In addition, the pouches would get clogged in the machinery prior to dropping into the can. This would result in one can having perhaps 16 pouches while another might have 24 pouches.
Solution:
Martin Vibration Systems recommended mounting an NTK-8AL Oscillator under each loading point. This small vibrator moves and compacts the pouches properly in the can. At the same time it keeps the pouches flowing freely down the loading tube. An estimated 40% rejection rate has now been reduced to less than 5%, and the cans have the proper number of pouches in them.

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.

Problem:
An Illinois ice cream manufacturer was having difficulties keeping sugar flowing down a feeding chute. The product would bridge and cling to the sides of the chute, creating inconsistency in the product blend.
Situation:
Their existing chute did not blend product consistently and would cling to its side. This created a problem with their product blending and the cleaning and maintenance of the chute was costly.
Solution:
Martin Vibration Systems first unit installed on the chute was our P-1.25 Piston Vibrator. However, because of noise and air consumption, the NTK-1 Aluminum Oscillator was used in its place. All flow problems have been eliminated with this application.

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 was 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.

Problem:
A Wisconsin Confectionery required equipment to separate and spread individual pieces of candy on the processing belt to prepare the candies for coating.
Situation:
This company had difficulty separating their small, dry chocolate and other flavored candy evenly for coating application. As a result, they were experiencing a high amount of waste from the clumping of the candy during this process.
Solution:
MARTIN® NTK® Oscillators (NTK 18al) were installed to the shaking-zone frame creating vibration with low noise between 60 to 70 dBa and no oil mist discharge. The Oscillators provide their line with instant start/stop capability, and the lubrication-free and wash down safe equipment has really improved their confectionery packaging processes significantly with low waste.
