Tips, advice and money saving ideas on how to keep your wood and greenwaste reycling equipment running longer and minimize downtime.

Horizontal Grinder Hammermill

In this post we will describe how to change the hammers in your pin & plate style hammermill for your tub grinder or horizontal grinder. We will also provide time and money saving tips to help you get the job done quickly and efficiently as possible. 


Tub Grinder – PTO (Dry Clutch) Maintenance and Operation Tips


(Warning) improper adjustment of the mechanical PTO (clutch) can cause catastrophic failure of the PTO the first time you feed material to the grinder.  Before operating the PTO on your tub grinder, be sure you’ve read and understand your manufacturer’s operations manual.

b2ap3_thumbnail_seattlemetalobject.jpgAs many of you may have seen in the news the past week, ( Metal Object Crashes Through Roof ) tub grinders do pose a risk when not operated and maintained properly.

We can see in the photo how damaged the tip is. Normal operation of a grinder with minimal contaminants ( Common Contaminants ) would not cause bolts to break free and eject the hammer tip in such a way.

Stay ahead of repairs and maintenance on your Tub or Horizontal Grinder!  Repairs are expensive, but downtime and can be extremely costly; especially when the material starts to pile up and your grinder is still down.   Our advice is to keep an inventory of common wear parts that will keep you running.  Here is a brief list of the most common items we recommend you keep on hand to help minimize downtime.
