2 x 72 belt grinder I just finished. Nothing fancy, design partially robbed from the interweb. I didn't do a build thread due to the simplicity. All in all it was pretty simple to make.
The KBDA-29(1p) VFD on there at the moment will soon be replaced with a KBCA-29(1p) due to the digital controller not working properly with the 3510 RPM motor I have. It runs fine at 60Hz and above but shudders from 40Hz to 55Hz. KB is sending me the Hybrid version which is not digital but will work with this motor. KB's tech support is second to none.
The platten assembly (except arm) is off the shelf. The cost is such that it was not worth making my own.
Specs:
3hp 3 phase 3510 rpm inverter duty motor.
Soon to be KBCA-29(1p) VFD
4" drive wheel
Speed range - 1850 to 5500 SFM (30Hz to 90Hz)
D-style platted from Origin Blade Maker (OBM)
Small wheel head & set of wheels from OBM (not shown)
Main frame is 2" square steel tube with .188" wall
Platten arm is 1.5" square steel tube with .250" wall
Base is a sheet of 1/4" steel with a 2" x 1/4" steel angle sub base.
Weight appox 150 lbs.
The amount of material these can remove quickly is amazing. It does it fast and with minimal heat. The radius's on the parts here were all done in about 5 minutes total. 3/4" hot rolled steel with an 80 grit ceramic belt to rough and 120 grit to finish.
Last thing to do is build a dust/spark collection system.
Thanks for looking.
