when used in manual grinders, it means that you have to do a lot of extra work using your biceps. ceramic burrs are rarely used in electric grinders; the main reason is probably that they are more fragile than steel and could shatter when getting in contact with
a device with burrs can produce the extra-fine grind for espresso or turkish coffee, medium-fine grind for pour-over and siphon brewers, medium for a dip or moka pot, and coarse for cold brew and french press. you can choose a device with ceramic or steel burrs. both will stay intact longer than grinders with blades.
if the burr is made of steel, then it absorbs the heat faster moving it away from the coffee. so, steel burrs are more effective at moving heat away from the coffee during the grinding process compared to ceramic ones. the other source of heat comes from the heat already stored in the coffee grinder as a
