Abstract: The present invention relates to a smart granular raw material conveyance system and a smart granular raw material conveyance method, wherein, when granular materials in powder form are conveyed along a conveyance line, the precisely metered granular materials are smoothly passed through a vertical pipe vertically installed in the conveyance line, and the granular materials are prevented from remaining or stagnating in the vertical pipe. The smart granular raw material conveyance system comprises at least one of: a first conveyance unit that conveys the granular materials in an amount corresponding to a first conveyance amount; a second conveyance unit that is spaced apart from the first conveyance unit and conveys the granular materials in an amount corresponding to a second conveyance amount equal to or different from the first amount; or a third conveyance unit that is spaced apart from the first conveyance unit and the second conveyance unit, and conveys the granular materials in an amount corresponding to a third conveyance amount equal to or less than the first amount or the second amount.

Abstract: The present invention relates to a powder material measuring rotary valve device for quantitatively measuring and sequentially discharging a powder material in the form of powder mechanically. The powder material measuring rotary valve device comprises: a hollow measuring housing having an open entrance to which a hopper is coupled and an open exit disposed opposite to the entrance; and a distribution module which is embedded in the measuring housing to be rotatable with reference to a first virtual axis perpendicular to a virtual line connecting the entrance and the exit, and delivers a powder material introduced into the entrance to the exit, wherein a predetermined fixed quantity of the powder material introduced into the entrance according to rotation of the distribution module is separately received in the distribution module and is then discharged through the exit in a first-in and first-out method.

Abstract: The present invention relates to a particle transfer system and a particle transfer method which allow preciously-weighed particles to smoothly pass through a vertically-provided vertical pipe of a transfer line when powder-type particles are transferred along the transfer line, and which prevent the particles from remaining or stagnating in the vertical pipe. To this end; the particle transfer system includes a particle transfer unit including at least one from among: a first transfer unit for transferring the particles in correspondence to first transfer information; a second transfer unit spaced from the first transfer unit to transfer the particles in correspondence to second transfer information, which is the same as or different from the first transfer information; and a third transfer unit spaced from the first transfer unit and the second transfer unit to transfer the particles in correspondence to third transfer information, which is the same as or smaller in amount than the first transfer information or the second transfer information.
