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.

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:

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.
