A device for grinding spices such as salt, pepper, cinnamon, etc. has a grinder rotor which has a removable keeper member which facilitates the ready removal of the rotor for cleaning or replacement. The grinder elements are made of ceramic material such as alumina silicate which eliminates the possibility of corrosion or rusting as with metal parts. The mill provides dual grinding action by utilizing separate grinding elements to provide either coarse grinding or fine grinding, as may be desired. For coarse grinding, the condiment only passes through the coarse grinding element while for fine grinding, the condiment first passes through the coarse grinding element and then passes through the fine grinding element.

A mill cutting structure is differently configured in three zones. Those zones are the center, the outer edge and in between. At the center has highly wear resistant material that has good temperature bond strength and high impact resistance. The outer periphery can have a material that is highly resistant to wear and impact. In between can be inserts such as used in the Metal Muncher® mills using sintered carbide shapes that resist tracking and create a chipping rather than a grinding action. The shapes should have high edge retention capability and shapes such as a double sided pyramid can be used. The wear patterns of prior designs are addressed to allow longer and faster milling of the fish.

A method and apparatus to pulverize materials directs solid materials through a generally horizontal chamber. A rotating center element that directs the material along the chamber by basic thrust using projections such as tines, paddles, knives or blades to develop motion and resulting kinetic energy of the material. The material is directed along the axis from the material inlet toward the material outlet and reverses flow at the end of the chamber to recycle back toward the material inlet causing particles of material to collide and fracture. The rotating speed of the center element can be adjusted to affect the grinding rates and particle size distribution. The rotating center element can also be fixtured to optimize material size reduction, differences in material density and the horizontal chamber can be tilted in a declined or inclined plane to affect the grinding rates and size reduction. This method of grinding and pulverizing can accommodate material feed stocks that have as much as 10% moisture since the grinding action creates heat and can drive off the moisture from the material.
