Topic: longevity of burr grinders (21 msgs / 474 lines)
1) From: Acorn54
just got the news on my solis 177 mulino. it had worn burrs from heavy use. 
comes as a shock as i only had it since december of last year and use it to 
grind 4 pots from a 4 cupper coffeemaker.  i roast my beans just into second 
crack and don't freeze them. just use fresh roasted beans. i'd like to know 
other people's experiences with their burr grinders. if you only can  get 9 
month''s use out of a burr grinder with moderate use then perhaps a whirly 
blade grinder is the way to go for auto drip brewing. -guy from long island

The good news should be it's under a year old. I would hope it be repaired
at no charge.(burrs replaced) The bad news is I don't believe it's the fault
of the burrs themselves. It's the design of the Solis grinder series.
Specifically the upper burr floats around too much causing excess metal to
metal contact. There's a detailed review on Coffeegeek I believe. (on the
Maestro as I recall, same collar design on Mulino & 166, same burrs.) I have
the same problem with my Maestro. I've resigned myself to replacing the
upper burr (thanks Jim and the DH tradition) limping  'till Christmas and a
grinder... probably Mazzer Mini but still investigating. This time the LAST
grinder purchase by our household!!!

I suspect that when you get it back with the new burrs, you will still 
find that it is not grinding evenly and producing dust and along with 
that bitter coffee.  The plastic base simply is not adequate to keep the 
burrs aligned through much use.  In fact, the burrs are probably dull 
because the base has allowed them to come into contact with each other 
and the new ones will do the same in a very short time.

Guy,
Don't underestimate the difference a good grind makes in a pot of drip 
coffee. If you were one of the people on the list that really doesn't care 
for drip, I suppose you could just smash the little buggers with a hammer and 
scoop them into the basket. But an even grind, no matter how fine or how 
course, is critical to proper extraction of coffee. The brewing or extraction 
method you use determines how fine or course you need to grind the beans to 
make that perfect cup.
I still use the first Zassenhaus I purchased 5 - 6 years ago for my weekend 
brews.
Just my CSA opinion on grinders,

Maybe getting the Super Jolly was a good idea for me.  It claims that the 
burrs are good for over 500 kg (1100 lbs) of grinding.  I figure that will 
last me about ten to twelve years at my present rate of 
consumption.  Replacing the burrs will be costy, but not nearly so much as 
a new grinder.  Plus, it is huge and people ask all kinds of questions 
about it, giving me the opportunity to provide them the best coffee most 
have ever tasted.

For the 'casual' user, the Solis grinder is OK.  The problem with it is longevity, as more and more people are waking up to that fact.  My 166 lasted about 6 months of light use, and then rapidly deteriorated.  Now I have a Rocky.
So - $125 = one Maestro that lasts about a year of solid use.
     $220 = one Rocky that will last about forever with new burrs every 5 years.
Do the math:  5 years of Solis = $625
              5 years of Rocky = ~$250
Hmmm, 2 year payback.   Therefore, one could justify a Mazzer Mini with another year of payback, and that doesn't include the better coffee you'll get the entire life of the Mazzer or Rocky.  Seems like a no-brainer to me.
It's a shame, too, as I really like the fit and finish, design, and quietness of the Solis 166 and Maestro.  I hate to rubbish them, but I have to 'warn' people of their shortcomings.  It's throwing money away.  
Shoot, get a Krups Gusto or Saeco Maestro or Idea espresso machine and buy the Rocky or Mazzer.  So what your espresso machine is 1/4 the cost or less.  You'll have far better espresso than a Rocky, Wega, Reneka, etc. with a Solis grinder.

The price I've seen for replacement burrs on the Rocky is $40.00 so the 
10 year costs would by $1,250 for ten years of Solis and $260 for ten 
years of Rocky.

That's assuming everyone's Maestro wears out at the same rate. In fairness
to Solis, I've been using mine since for nearly 10 months nearly everyday
with no problems, save the annoying static. I'm probably grinding 1.5 pounds
of coffee per week. I don't see any signs of failure either. Still getting a
very even grind for espresso and drip.

Sounds like you might have passed a pebble through
that thing. Even frozen beans should shave and
fracture properly through a burr grinder. I've used a
Braun burr grinder for the better part of two years
passing nearly 800 auto-drip pots and probably 100-200
loads of espresso through and it is still going
strong, just takes a little longer.  I believe the
Braun has flat burrs. I recently relegated it to our
camper and replaced with a DeLonghi with conical
burrs. We've probably run at least 30-50 drip loads
through the DeLonghi + around 25 espresso loads of 4
double shots each and no problems.
If you talk to a professional roaster worth his/her
weight, and look at their setup, it will include a
de-stoner or it might be called a stone vacuum.  This
machine is where the cooled beans are first
transferred and it is designed to suck up the roasted
beans (which are lower in density than pebbles which
are prevalent in dry-processed coffees and present in
some wet-processed ones) into another handling area
and leave the stones behind.  The stones if not
removed will destroy a burr grinder upon contact and
while it will grind after that, it will do such a
terrible job that you'll know that something is wrong.
 A set of titanium burrs in a professional machine
will cost around $300-500 and stones in your roasts
will ruin your reputation as a roaster, not to mention
replacing your customers burrs to keep in good
standing.
I haven't personally gotten any stones in coffee from
Sweet Maria's but I have from other suppliers, and
although small, I roast in small enough batches to
look over the cooling beans and see them if they are
present.  I also weigh each batch and roast a given
volume so that if I see a noticeable difference in the
weight per given volume I do a quick scan to see if
there are stones present before roasting.
I'm not sure if this is the situation with your
grinder, but it is certainly a possibility given your
symptoms.

Nope, it is saying we have heard reports on a sufficient number to say 
that an average for the Solis basic design grinder of one year is 
generous.
In addition, I have taken one completely apart.  When I looked at the 
structure that is there to hold the burrs very close to each other and 
considered the stresses the structure has to hold up to, it is obvious 
that it cannot last. The burrs will sooner or later  come into contact 
with each other during normal use resulting in dulling and powered 
coffee.

Yes, I certainly won't argue that fact.  The burr 'teeth' on the Solis are so small that any damage to them would be very apparent and cause a lot of dust.

Better grinder first. You'll most likely get a better brew roasting in a
frying pan and grinding with a Rocky than roasting in an Alps and grinding

I wonder if Tom uses a vacuum de stoner before repackaging green beans to
sell?  I think I remember him talking about all the really strange stuff he's
gotten out of shipments over the years.

And to balance that out, mine wore out in about three months grinding about
0.5 pounds of coffee per week.  It still grinds, but now it has a lot of

I think the vacuum de-stoner only works with the less dense roasted

I don't go through near the coffee of some members, but I *have* gotten a
total of two stones so far.  I remember that one was in some Ethiopian
Hararr Longberry - I think that's the little flat one.  The other one was
about the size and shape of a small coffee bean - it was just different
enough that I spotted it.  I *think* that was in some monsooned Sumatran.
Enjoy!

well i got my solis mulino back with the new burrs installed. runs like new.
i doubt i grinded up any stones. i get my beans from tom at sweet marias and 
that's all i used.
i just think the use i  put it through (about 4x per day for my kitchenaid 
ultra compact 4 cupper) was what did it. i think these grinders are designed
