My idea is to exchange here all we know about grinding from our own experience and from other sources, including Internet.

I own Gaggia MDF. The instructions for this grinder say that the proper grind range from grains that look like sand to grains slightly coarser than flour. But I think that these guidelines are too vague. I simply use 5 or 6 setting to make grinding which I like. So whatever grinder you have, read the instructions, but play around to find the proper grind.

I tried different grinds. I found two that work very good on me in taste. They are produced in Italy ? Maestoso and Benevenuto. Both are not very fine grinded but they seem to work very good with the pavoni because the taste is perfect.

\r\n\r\nGood idea. Useful. Actually I like gathering all kinds of tips about making coffee and I have a lot of info. Sometimes I don't remember the source of this info. \r\n\r\nThis is what I have about grinding:\r\n\r\nWhen you make espresso, grinding and tamping from go together hand-in-hand. The idea is that the packing of the coffee grinds provides resistance for the heated water. This resistance causes the water to flow slowly through the grinds and extracting the components of "espresso" at the coffee-water interface. This extraction pressure causes the gases to pass into solution, and this way the elusive crema is formed, a sign of a good pull.

Some info about flat plate burrs & conical burrs - which is better\r\n\r\nBoth style of burrs are used in home and commercial grinders. They produce a consistent grind worthy of any high end or home espresso machine. \r\n\r\nThe conical burrs are usually used on the very low-speed gear reduction grinders. The flat plate burrs are used on all qualities of grinders, from the low priced high-speed grinders all the way up to the low-speed direct drive commercial grade grinders.

For me grinding is such individual process, almost like a ceremony and after you learn the main rules you can try and investigate

Read this page. This is about grinding\r\n\r\nhttp://www.mme.tcd.ie/~jbadger/grindingpage.html

The best way is to read the instructions manual for your grinder carefully and do exactly what they say.
