Any reason to NOT use these in a Mini E? (Aside from the reasons given for using stock Mazzer SJ burrs in the Mini E.)

18.8 g coffee dose? omg xD

Good question. Only consideration I can think of is whether the motor is powerful enough for it not to stall (the mini e motor is less powerful than SJ)
If you do a search, there were initial reports of a few experiencing stalling in the SJ after installing the duranium burrs (hasn't happened to me and I haven't heard the issue in recent posts)

Would be interested to hear from someone who has installed them in a mini-e

The fact that Mazzer put SJ burrs into the Mini-E gives an indication that the 250 W motor is good enough (SJ has 350 W) to run SJ burrs. I've only used Redbird through my SJ, and there was no detectable difference between the Duranium and stock burrs.

While I respect and believe those posts that found issues, I wonder if there was some other issue in play. And, since my OP, the Duraniums remain the best upgrade I've ever done and transformed the SJ in a hella grinder. If it were me, I'd do it, the worst case is to send them back or sell them on the Buy/Sell forum.

As referenced in below, I don't believe the burrs in the Mini-E are SJ Burrs (i.e. Mazzer does not put SJ burrs in the Mini-e)

Difference between Mazzer Mini E burrs and Super Jolly burrs?

The burrs from espressocare are not titanium alloy or titanium nitride coated. They're just steel burrs.

I ordered a set a couple of weeks ago for $65. When they came they looked and hefted suspiciously like steel. I weighed them and they were a gram or so heavier than the originals. They were also attracted to a magnet, and they said "Food Friendly" on them, like these for $29 from eBay: http://www.ebay.com/itm/Mazzer-Super-Jo ... Sw2ENW7xdl.

I emailed Stefano about this. His first response was that they were titanium, as specified by the Italian manufacturer. His second response was that he called the manufacturer and learned they were indeed just the Food Friendly steel burrs (18NiCrMo5 to be specific). He has adjusted his listing (though the price remains at $65): http://espressocare.com/products/item/b ... -dura-mill.

I returned them for a refund.

About a month ago I ordered a set of these Duranium burrs for my Super Jolly after reading this thread. I installed them and ran a bit over 20lbs of stale coffee I had to season them. I dialed in some espresso beans that I am very familiar with. The only difference I noticed was the grind speed. It was significantly faster than the original burrs. Other than that the flavor was exactly the same. Grind quality(clumps) was exactly the same, but this could be due to the anti-static screen since I have the E version of the Super Jolly. Are they worth it? Sure. I still have them installed in mine. For only a few extra bucks over the original burrs you get an increase in grinding speed and from what I understand they should last longer as well. Other than that I wouldn't expect a difference in the cup. Non at all.

For those that are interested, I have three grades of SJ burrs available. Gas carburized, D2 tool steel, and D2 plus TiN. Same geometry for all three but slightly different than the SJ oem.

New burrs make a difference.

I have no idea how many shots were on my "church lady" SJ but the burr set in it was a little dull.

After over a month of daily use, the grind weight/time is still as consistent as it was the first day,

New burrs rock, regardless of what they are made of and how they are fasted.

Regarding the question of using the burrs in a Mazzer Mini, I installed them a few days ago and have had no issues.

My grinder is an timer version which I upgraded with the Super Jolly carriers and a doserless chute

- upper burr carrier: http://tinyurl.com/z7xotrk

- doserless chute http://tinyurl.com/hqnw7pr
- backing plate http://tinyurl.com/zzzkd8u
- doser screen http://tinyurl.com/gv49x7q

I also wanted a timer, so I bought the Auber http://tinyurl.com/zd788sb

I've only had it for a few days and I've not fully formed an opinion but can state the following

I've had no issues with jamming except when I pulse the grinder very quickly and this is not a material issue.

I did have a minor alignment issue. When seating the burrs in the carrier there is some lateral movement presumably to support alignment. The play is the same as the stock burrs. The dry eraser alignment technique helped clear this up http://tinyurl.com/z9mfxfe

Removing the lower burr carrier is hard. I levered it up via a screw driver, but the using 3 long screws would have been much smarter. I'm lucky that I didn't hurt anything. http://tinyurl.com/hxg9wc7

The doserless chute works well and is very easy to install. The backing plate is designed for the Electronic. The Timer grinder is missing the appropriate screw holes which are easily drilled. I found the dozer screen clogged and created clumps. Removing it is much better.

Clumping is better than the original burrs and now a minor issue. It will be interesting if this improves further with more use. Static causes grinds to stick to the funnel which a gentle tap clears up nicely. It's much faster with 17g taking about 7.5 seconds.

As for taste, it's different. Chocolate and wine notes are more pronounced, less bright, but a bit harsher. I've only run 2-3 pounds so it's too early to truly comment.

The timer is fun. A bit large and looks like one of my high school radio shack projects but still recommended.

Given all of this, should I have just sold the mini and bought a mini-e or SJ? yeah probably.......
