Mill

A mill comprising at least the following elements:

• a plastic rotating part having an inner surface provided with first anchoring elements, and first support means emerging from an inner central portion of the plastic rotating part;
• a high-hardness rotating part, provided with second support means, which rest on the first support means and are complementary thereto to prevent rotation of one of the rotating parts with respect to the other;
• a high-hardness stationary gear having an outer surface provided with first locking means, and a central cavity;
• a plastic stationary part having an outer surface provided with second anchoring elements along which the first anchoring elements of the plastic rotating part pass;
• the plastic stationary part being provided with second locking means, which rest on the first locking means of the high-hardness stationary gear and are complementary to the first locking means to prevent the rotation of one of the parts with respect to the other;
• wherein
• the high-hardness rotating part has a plurality of teeth on an outer surface and the high-hardness stationary gear has a plurality of teeth on an inner surface, such that when the mill is assembled, a clearance remains between the high-hardness rotating part and the high-hardness stationary gear.
