A grinding system that includes a grinder attached to a grind size adjustment ring. Also, a potentiometer attached to the grind size adjustment ring, so as to provide a grind size measurement to a controller. The controller selects a grinding duration based upon the selected grind size measured by the potentiometer.

An apparatus (10) for micronizing an inorganic salt, having a receiving vessel (14) for receiving the salt (46) to be micronized in an interior of the receiving vessel (14); a grinding unit (22) for comminuting the salt (46) to be micronized located in the receiving vessel (14) and for forming micronized salt particles (54); an ascending pipe (24), which is connected fluidically to the receiving vessel (14) and serves to transport the micronized salt particles (54), wherein one end of the ascending pipe (24) has an outlet orifice (38) through which the micronized salt particles (54) can flow out of the apparatus (10); a fan (26) for generating an air stream (40); and a housing (12) with an air outlet (44) and an air duct (42) connecting the fan (26) to the air outlet (44), wherein the air duct (42) is separated by at least one wall from the interior of the receiving vessel (14), such that the air stream (40) generated by the fan (26) does not flow through the interior of the receiving vessel (14), and wherein the air outlet (44) at least partly surrounds the ascending pipe (24) in a region of the outlet orifice (38).

A coffee grinder-doser includes a grinder-doser body enclosing a grinding chamber which houses first and second mills configured and mutually positioned to grind coffee beans into powder. An external ring-nut which is gripped and rotated by an operator integrally connects to the first mill. A nut screw with a longitudinal axis, inside the grinding chamber, is engaged with an external thread of the ring-nut to translate the first mill along the longitudinal axis. The ring-nut includes a ring-nut body and indices defining the angular position thereof. The grinder-doser body includes a fixed reference for the indices. The ring-nut is associated with a graduated ring having the indices, and a cover at least partially removable to lock the graduated ring between the cover and the ring-nut. The cover is fixed to the ring-nut body by a partially removable couple for adjusting and locking the angular position of the graduated ring.

An electric motor operated kitchen appliance has a base unit having an electric motor and a preparation vessel, which can be connected to the base unit and into which a rotating element protrudes, which can be rotationally driven by means of the electric motor, wherein a grinding element, which, with a grinding area of a grinding vessel held on the preparation vessel, forms a grinder, can be connected to the rotating element. To advantageously further develop the kitchen appliance, the grinding element is connected to the rotating element via a coupling element having at least one elastic partial area.

The invention relates to a coffee grinder system comprising a coffee grinder, which contains a housing and a grinding mechanism arranged in the housing, and comprising a drive device for driving the grinding mechanism. The coffee grinder system is distinguished in that the coffee grinder is or can be movably and/or self-centeringly coupled to the drive device.

A coffee grinding machine including a first burr and a second burr. At least one of the first burr and the second burr is rotatable about an axis of rotation, the burrs being mutually cooperating to grind coffee. The machine includes a motor which rotates at least one of the burrs with respect to the other, wherein the axis of rotation of the motor does not coincide with the axis of rotation of the burrs so that the coffee which is ground by the grinders is directed to an output of a conveyor cone for use thereof.

A method and crushing device for coarse-grained material. The crushing device includes one first axially rotatable grinding mechanism and a second grinding mechanism which is fixed with respect to the first axially rotatable grinding mechanism. The second grinding mechanism accommodates the first axially rotatable grinding mechanism and is in operative connection with the first axially rotatable grinding mechanism for the purpose of crushing the coarse-grained material. The axially rotatable grinding mechanism has one transport channel for the respective material to be crushed. The transport channel includes a first section extending axially and a second section which adjoins the first section at an angle and passes through an outer lateral surface of the axially rotatable grinding mechanism.
