An industrial mixer that doesn’t turn will put a halt to your production process. If you’re having issues with your mixer’s output shaft not rotating, there are a few things you should check before calling in the experts.
Most of the time when an output shaft doesn’t turn, it’s because the mixer’s internal parts are broken. There are three main reasons this can happen. Let’s go over these common causes and how to troubleshoot them.
Did you find a loose or disconnected coupling? Whoops! This is a quick and easy fix. All you have to do is properly align the reducer and coupling, then tighten the coupling to spec. If this didn’t fix your problems, check the remaining causes below.
If your key is missing or sheared off in the input shaft, your output shaft will not turn. Simply replace the key and you should be good to go. Be sure to remove the pieces if the key sheared in half. If your output shaft still isn’t turning after replacing the key or tightening a loose coupling, you probably overloaded a reducer.
Check the rated capacity of your reducer(s). If you’re experiencing problems and overloaded a reducer, the damage is probably already done. At this point, you should replace any broken parts and be sure your reducer(s) fall within their rated capacity.
It is also important that you aren’t experiencing any overheating, excessive noise, vibration, or oil leakage from your mixer. These are all telltale signs there's something wrong with your industrial mixer. Check out our recent post about noise and industrial mixers. Get in the habit of conducting routine checkups on your mixing equipment to ensure everything is in good health.
