I have a motorized CL Mill and I'm trying to grind cornmeal with it.  I've replaced the auger to the corn and bean auger but I'm having a difficult time getting my grind right.  It seems as it it starts going fine but after a few min it sounds like a piece of corn gets hung up s0mewhere and it makes a loud whining noise.  I have to turn it off and open up the grind and then crank it ack down only for it to happen again in a ninute or two.  Any ideas as to what I'm doing wrong here?  Ihm I'm using popcorn as my grain.

Thanks!
