れるのである。 When the classification container 1 etc. is rotated via the pulley 6 and a suspension such as slurry is injected into the classification chamber 8 through the injection path 11, the suspension is transferred to the rotating plate 1.
A suitable number of swirling blades 15 attached to the classification chamber 8 create a swirling flow, and the coarse powder in the suspension is subjected to centrifugal force, separated and concentrated toward the inner wall of the classification chamber 8, and flows down to the first collection. While being collected through the port 7, the fine powder is separated and concentrated in the central part of the classification chamber 8, ascends, and is collected through the second collection port 13 and the collection path 14 in sequence.

要はない。 Note that the reason why the lower half 1a of the container 1 is shaped into a funnel shape is to prevent the deterioration of classification accuracy without reducing the swirling flow velocity, and it is not necessarily necessary to make the lower half 1a into a funnel shape.

旋回用羽根１５は懸濁液に旋回流を起させるも
のであれば配置位置、形状は問わない。 The arrangement position and shape of the swirling vanes 15 do not matter as long as they cause a swirling flow in the suspension.
