Choosing the Right Tub Grinder

This is a brief introduction to tub grinders and some of the factors you should be considering when planning to purchase a new or used tub grinder.

Tub grinders have been around for roughly 30 years and are aptly named for the large round tub or infeed.  Tub grinders rely on gravity and tub rotation to feed material into the hammermill at the bottom of the tub which performs the grinding function. 

One of the first choices that buyers face is whether to buy a new vs. used grinder. If profit is a concern to you, then read on. Like cars, grinders depreciate rapidly in the first few years and many buyers realize too late that they have lost as much value on their new grinder as they made operating it. I believe that Grey Livingston said it best – “Driving a brand new car feels like driving around in an open billfold with the dollars flapping by your ears as they fly out the window.”
