A tobacco grinder allowing direct transfer of ground tobacco to a smoking implement to eliminate waste includes an upper cover, a middle cover, and a material receiving base. The upper cover is rotatably positioned at one end of the middle cover the material receiving base is detachably connected to the end of the middle cover. A space between the upper cover and the middle cover defines a grinding cavity. A filter hole is defined on the middle cover, and a discharge hole is defined on the material receiving base, forming an escape path for tobacco which has been ground into particles. A sealing member is detachably coupled to the discharge hole, thus the discharge hole can be closed or opened. The ground tobacco can be directly transferred as required into the electronic cigarette.

What is described is a new grinder, which serves to grind coffee beans and which is embodied as conical grinder. To improve the grinding process, the grinding cones and/or grinding ring encompass grinding surfaces that may define an angle of inclination, which may be in each case greater than 90? and smaller than 180?, relative to a tool reference plane.

An improved herb and spice grinder includes a top section with teeth, a grinding section with teeth, an annular spacer, and a base section, the annular spacer includes an upwardly-depending dividing wall and a plurality of doors hingedly coupled superjacent the dividing wall so as to enable each herb and/or spice to be separated prior to grinding. The herbs and/or spices are loaded into the grinding section. The top section is rotatably attached to the grinding section, and the annular section is rotatably attached between the grinding section and the base section in a stacked fashion.

What is described is a new grinder, which serves to grind coffee beans and which is embodied as disk grinder. To improve the grinding process, the first and/or second grinding disk, respectively, encompass grinding surfaces that may define an angle of inclination, which may be in each case greater than 90? and smaller than 180?, relative to a tool reference plane.

The present disclosure surrounds a flat burr grinder with increased ease of maintenance, adjustability, and/or precision as related to the grinding of media such as coffee beans. The apparatus described herein includes a grinding assembly which is optionally configured for disassembly at a location which corresponds to the location of the burrs to allow for easier maintenance and adjustability without affecting the gap between the burrs as last set by the user. An optionally interchangeable pre-breaker auger allows for adjustability of the particulate size of grinding material which is introduced to the burrs for grinding.

A grindstone corresponding to a rotatable grindstone or a stationary grindstone can be incorporated in a grinding device and is used for grinding raw materials. The grindstone includes a main body part and an outer circumferential ring part that can be detached from each other. The main body part has a coarse grinding part in which coarse grinding grooves corresponding to first coarse grinding grooves and second coarse grinding grooves for initially grinding the raw materials are formed. The outer circumferential ring part has a fine grinding part corresponding to a wall part in which fine grinding grooves for further grinding the raw materials ground by the coarse grinding part are formed. When the main body part and the outer circumferential ring part are assembled, the fine grinding part corresponding to the wall part is located at an outer circumference of the coarse grinding part.
