Abstract: A grinder for grindable food materials such as salt and peppercorns. The grinder (10) has a body (11) which contains first and second grinder elements (15 and 17). The grinder elements have opposed grinding surfaces (16 and 18), between which grindable material can pass to be ground or milled when relative rotation therebetween occurs. This relative movement is caused by handle (13) driving shaft (14) connected to grinding element (15). An adjustment mechanism to adjust the distance between the grinding surfaces is included. The adjustment mechanism has a connector (30) which connects element (15) to the grinder body (22). Rotating the connector (30) by knob (35) causes the distance between the grinding surfaces (16 and 18) to be adjustably altered.
