Case Study: MARTIN® XHD™ Vibrator Prevents Production Breaks

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 installed on the pug mill were not sized properly, which required them to operate at maximum output. This resulted in frequent motor failures and the failure of bearings.

Solution

MARTIN^® Vibration Systems replaced their existing electric vibrators with two XHD™ Series XHD-C12T vibrators 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 that the output became smooth with no plugging or build-up, which no longer required them to shut down production.
