Abstract:
The present invention relates to an industrial powder making device, including: a powder making cylinder body, spiked hammer arms, a front oblique hammer, vertical hammers, a hammer aim, a detachable rack, a detachable rack inner bulge, spiked blade arms, a front oblique blade, high-hardness wear-resistant alloy sheets, a blade arm, a rotating shaft, a rotating shaft groove, a clamping piece, a feeding port, a discharging port, bearings, a rotating power module, a liquid nitrogen storage tank, a pipeline, a valve, nitrogen input holes, a nitrogen output hole, a fine particle collection device and a disc bevel discharging control device. And an operating method is: crushing the ore by the spiked hammer arms, grinding the ore by the spiked blade arms, cooling with nitrogen, controlling equivalent input and output of the ore, and crushing and grinding the ore according to an established route, thereby realizing rapid powder making.

Claim (Index 5):
A powder making device, comprising a powder making cylinder body ( 1 ), spiked hammer arms ( 2 ), spiked blade arms ( 8 ), a rotating shaft ( 12 ), a rotating shaft groove ( 13 ), a clamping piece ( 14 ), a feeding port ( 15 ), a discharging port ( 16 ), bearings ( 17 ), a rotating power module ( 18 ), a liquid nitrogen storage tank ( 19 ), a pipeline ( 20 ), a valve ( 21 ), nitrogen input holes ( 22 ), a nitrogen output hole ( 23 ), a fine particle collection device ( 24 ) and a disc bevel discharging control device ( 25 ), wherein the powder making cylinder body ( 1 ) is cylindrical, and centers of an upper part and a lower part of the powder making cylinder body are fixed by the bearings ( 17 ) respectively; the rotating shaft ( 12 ) penetrates through the two bearings and is connected with the rotating power module ( 18 ), and the rotating shaft groove ( 13 ) is formed in the rotating shaft ( 12 ); the rotating power module ( 18 ) is installed outside the powder making cylinder body ( 1 ) and provides a rotating speed greater than  1000  revolutions per minute for the rotating shaft ( 12 ); the disc bevel discharging control device ( 25 ) has a shape of a funnel, a lower round hole has an adjustable size, and the rotating shaft ( 12 ) penetrates through the funnel-shaped lower round hole; the disc bevel discharging control device is installed in the powder making cylinder body ( 1 ), and the powder making cylinder body ( 1 ) is divided into an upper part and a lower part; the spiked blade arms ( 8 ) are composed of a front oblique blade ( 9 ), high-hardness wear-resistant alloy sheets ( 10 ), a blade arm ( 11 ), a detachable rack ( 6 ) and a detachable rack bulge ( 7 ); the front oblique blade ( 9 ) and the blade arm ( 11 ) are square; the front oblique blade ( 9 ) is a blade which is obliquely fixed to an outer end of the blade arm ( 11 ); the detachable rack ( 6 ) is fixed to an inner end of the blade arm ( 11 ); the blade arm ( 11 ) is narrow in exterior and wide in interior; the vertical hammers ( 4 ) are uniformly fixed in the middle of the blade arm ( 11 ), and a height of the hammer arm takes a height of the front oblique blade as the largest height and is sequentially decreased towards the center; the detachable rack ( 6 ) is annular, and an inner circle of the detachable rack is matched with the rotating shaft ( 12 ); the detachable rack inner bulge ( 7 ) is matched with the rotating shaft groove ( 13 ); the spiked blade arms ( 8 ) are superposed on the lower half part of the disc bevel discharging control device ( 25 ) of the rotating shaft ( 12 ) by virtue of the detachable rack ( 6 ), and the next spiked blade arm ( 8 ) is longer than an upper one; the clamping piece ( 14 ) is used for fixing the spiked blade arms ( 8 ) superposed on the rotating shaft ( 12 ); the blade arm ( 11 ) needs to rotate in the powder making cylinder body; a front side, an upper side and a lower side of a rotation direction of the blade arm are coated with high-hardness wear-resistant alloy sheets ( 10 ), and the front oblique blade ( 9 ) is also coated with the high-hardness wear-resistant alloy sheets ( 10 ) on three sides like the blade arm ( 11 ); the spiked hammer arms ( 2 ) are composed of a front oblique hammer ( 3 ), vertical hammers ( 4 ), a hammer arm ( 5 ), a detachable rack ( 6 ) and a detachable rack bulge ( 7 ); the front oblique hammer ( 3 ), the vertical hammers ( 4 ) and the hammer arm ( 5 ) are square; the front oblique hammer ( 3 ) is a hammer which is obliquely fixed to an outer end of the hammer arm ( 5 ); the detachable rack ( 6 ) is fixed to an inner end of the hammer arm ( 5 ); the hammer arm ( 5 ) is narrow in exterior and wide in interior; the vertical hammers ( 4 ) are uniformly fixed in the middle of the hammer arm ( 5 ), and a height of the hammer arm takes a height of the front oblique hammer ( 3 ) as the largest height and is sequentially decreased towards the center; the detachable rack ( 6 ) is annular, and an inner circle of the detachable rack is matched with the rotating shaft ( 12 ); the detachable rack inner bulge ( 7 ) is matched with the rotating shaft groove ( 13 ); the spiked hammer arms ( 2 ) are superposed on the upper half part of the disc bevel discharging control device ( 25 ) of the rotating shaft ( 12 ) by virtue of the detachable rack ( 6 ), and the next spiked hammer arm ( 2 ) is longer than an upper one; the clamping piece ( 14 ) is used for fixing the spiked hammer arms ( 2 ) superposed on the rotating shaft ( 12 ); the nitrogen input holes ( 22 ) are uniformly distributed in a bottom of the powder making cylinder body ( 1 ); the liquid nitrogen storage tank ( 19 ), the pipeline ( 20 ) and the valve ( 21 ) provide an appropriate amount of low-temperature nitrogen for the powder making cylinder body ( 1 ) by virtue of the nitrogen input holes ( 22 ); the nitrogen output hole ( 23 ) is formed in a top of an upper powder making cylinder body ( 1 ) and connected to the fine particle collection device ( 24 ); and the feeding port ( 5 ) and the discharging port ( 6 ) are respectively formed in an upper part and a lower part of the powder making cylinder body ( 1 ).
