I have run a fair amount of coffee through the grinder since finishing the instant rice, but just to be sure I just took the inner burr out... no signs of any rice particles. I wiped both burrs down as best I could with a paper towel.

Here is a video of me grinding. (I have tried with and without RDT, no difference in grinding). This was actually a pretty quick one @ 160 revolutions:

1) Do you use RDT? With my 2013 model, I need now around 20- turns for 16 gr. However, if i add too much water (I add drops, don't spray which is actually better, I think ) or if the water is predominantly on the first beans going in the grinder, I need very, very many turns more......
2) Maybe the burrs are a bit 'slippery'? Lower the inner burr, use a dry tough (tooth)brush on both burrs to get them really clean and then grind the beans without RDT. Of course you will get a lot of static, it is just to see if you have to turn less, 200 is crazy.

Ah! Just seen your vid. The burrs are not grabbing the beans well: too slippery! Try the brush, even though the burrs might look clean, there might be residue from rice or oily beans that you cannot see.

I bought mine new about nine months ago, I've since put about 40-50 pounds through the it. I grind 15g doses for espresso and it takes me about 25 revolutions. Take so pictures of your burrs, do they seem damaged at all??

It takes me 20 to 25 turns for 18 grams.

How long does it take you to pull shot? Curious to know how good your grind size is.

Perhaps run a few doses of Grindz through. Then hit the burrs with canned air or an air compressor if you have one.

I wouldn't under any circumstances used canned air to clean out a grinder. Most of them have bitterants added to them.

Good to know, thanks Tom!

I would turn the grinder over, take out the rotating burr (one allen screw) inspect and thoroughly clean and check for any thing that may be the cause of your problem. My theory is moisture caused by RDT.

When I saw the video it looked like the ground coffee was not coming out evenly. It seemed to take practically no physical force to turn the handle. Something is very very seriously wrong here. I have always run a few grams of Irish oatmeal through mine from time to time. It is very absorbant and cleans things very well. It looks to me like the burrs are highly faulty. There should be a fairly even distribution of ground particles along with the fine particles that result from some shattering. The relatively low speed of the Hg-1 results in a very good distribution of particle sizes.

I still say, put a sheet of paper under the burrs with the "spout" off so the coffee falls straight down and see if the particles form an even circle. This is important! Perhaps it is grossly misaligned.
