I understand. What kind of mills are you running? CPM, Sprout? I worked in feed mills for about 10 years plus my Dad retired from purina so i have been around them for awhile too but i have been out of that line of work for about 10 years now. I have never ran any wood/type pellet. but have run a bunch of other stuff but strictly from a maintenance standpoint never formulation. We just had to fix the things when they got a little crazy with urea or some of that binder crap. Well good luck. If you need any parts let me know. I also run a little millwright service spectializing in small plant support. I can get some decent deals on rolls and such.
