Mill

FIELD: human vital needs satisfaction.

SUBSTANCE: mill (1) with the first grinding element (11) and the second grinding element (15), in which two grinding elements (11, 15) rotate relative to each other in such a way that coffee beans are ground by the grinding elements into coffee powder and with a pickup wheel (25), rotating with the first grinding element, the mentioned pickup wheel is used to move ground coffee powder along its border area from the grinding elements (11, 15) through an output channel (6-3). The border area of the pickup wheel (25) is made conoidal in the direction to the grinding elements (11, 15) with a concave profile, so that it forms an inner high edge (Ri) and an outer low edge (Ra), and the pickup wheel (25) contains lots of pickup blades (26) distributed in the border area peripherally.

EFFECT: increased reliability and efficiency of the device.

SUBSTANCE: device relates to the field of producing fine powders including nano-sized ones. The device contains a hollow perforated cone-shaped electric motor rotor wherein, the same as in the grinding bowl of a common mill, proceeds disintegration of a substance to produce a nano-sized powder. On the inside the rotor has teeth or spikes performing disintegration of larger substance globules and creating aggressive vortex flows that continue milling the substance to ever smaller particles. Grinding is additionally promoted by vibration of the rotor suspended on magnet bearings during its high-speed rotation; the magnet bearings proper are designed so that to enable correction of the rotor vertical and horizontal microvibrations in accordance with the preset algorithm. Grinding is performed due to simultaneous action of three factors: disintegrating effect of the rotor spikes, aggressive air or gas vortices, rotor microvibration in the longitudinal or crosswise direction. Grinding proceeds within two spaces simultaneously: inside the hollow rotor and in the space between the rotor and the stator. Thanks too the device design peculiarities grinding is performed into two substance fractions at once.

EFFECT: invention enables production of fine powder with dispersity less than 100 micron.
