I am just back from a whirlwind trip through the heartland where I had the opportunity to visit a few plants and equipment makers installing and using vibrators. In the plants in particular, I came across a few instances of damaged and repaired equipment, such as cracked hopper walls that had to be re-welded. Too often, the vibrator gets a bad rap in these situations, where in reality, the damage is a function of not sizing or installing the vibrator correctly. In this post, I want to make three easy recommendations for industrial vibrator users to hopefully prevent future perception of industrial vibrators causing damage:
1) Call a professional for sizing help. While we do publish some sizing guidelines to help pick an appropriately sized vibrator for material load sizes and bin or hopper wall thickness, sizing and recommendation can be perfected more with more information. What if your hopper is a large dimension, but you only want to vibrate when it is almost empty for clean out? What if your bin wall isn’t thick enough to handle the vibrator appropriate to you material load? What if you have bolted instead of welded construction? All industrial vibrator manufacturers and their distributors or representatives will typically have very experienced and knowledgeable staff to help. We know that in today’s world, people want to Google search, find and answer and run with it. However, a five or ten minute call once you have gathered your first info can pay big dividends. We are here to talk and help. Contact us.
2) Read the installation manual. It will tell you how to attach important elements such as stiffener plates, mounting channels and bolts. Believe it or not, even something as simple as nuts and bolts have a huge affect on the performance and integrity of the vibrator.
3) If you don’t call us or read the manual, remember this one key item to installation: stitch weld the mounting channel and DO NOT weld the corners of the mounting channel to your bin or hopper wall. This is the number one cause of cracking that I have seen. The corners need a little give for the vibration. If they are welded down, you WILL see cracks form in your bin or hopper wall extending directly out from those mounting channel corners. That doesn’t help anyone…except maybe the manufacturers of the bins and hoppers.
Certainly, there are more elements that can help protect your equipment and ensure that the investment you make in industrial vibrators is as effective as possible. But, if you want the fast answer, please at least pay attention to these main points.
