Case Study: Reduce Costs by Implementing A MARTIN® NTS™ Non-Impacting 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 the screen deck and supports, which in turn required costly rebuilds and repairs.

Situation

Their existing rotary electric vibrators were mounted on 4′ x 6′ screens, which were used to screen pyrites from the exhaust gases. They run at 3600 revolutions per minute and are mounted to an arm that 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 MARTIN® NTS™ Non-Impacting Vibrator (NTS-50/04) 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.
