You might be able to get hold of a Weber Spice grinder set:
This set is a screw on grinder and three jars, the grinder mechanism is ceramic (lifetime guarantee) and can grind from very coarse to very fine.
It comes with three jars you can fill with different spice mixes and swap over onto the grinder mechanism.
And it comes in different colours.
