摘要： PROBLEM TO BE SOLVED: To set a precise classifying point corresponding to the values of characteristic physical properties of a raw material powder and efficiently obtain a classified powder product in a sharp distribution of particle size by whirling and streaming high pressure air and making a Coanda diameter of a Coanda block changeable corresponding to the values of the physical properties of the raw material powder. SOLUTION: High pressure air which becomes a whirling current by leading air out of a leading path 43 is introduced into a raw material supplying nozzle 16 from a high pressure air supplying nozzle 41 and a raw material powder is carried in the raw material supplying nozzle 16 together with the whirling current having high dispersing function and introduced into a classifying region 30. A Coanda ribbon 26 is so installed as to make the powder particles which are led in the vertical direction successively from a lower part of the raw material supplying nozzle 16 draw a long elliptical arc. Since the Coanda ribbon 26 is formed like a kind of a ribbon, it is easy to move the Coanda ribbon 26. Consequently, the Coanda diameter of a Coanda block can be changed optionally, so that the optimum curving current corresponding to the values of characteristic physical properties of a raw material powder of, for example, a toner can be obtained.

摘要： PURPOSE:To effectively classify sand produced by a sand producing device into the desired particle size and also to make the equipment compact and inexpensive. CONSTITUTION:A sand producing part 1 which has a feeding chute 4 on one side of the upper part and whose almost lower semicircular part is constituted of a grate 5 set at a desired clearance and whose upper semicircular part is constituted of a repulsion plate 6 to form a crushing chamber 7 and in which a hammer 11 rotating at high speed is arranged in the crushing chamber 7 with the rotation locus of its maximum outer diameter being close to the repulsion plate 6, a classifying hopper 2 which is arranged below the grate 5 and in which sand grain falling and discharged from the great clearance of the sand producing part 1 is pneumatically classified during the falling to separate and remove fine particles and the sand grain within the prescribed particle size is taken out from below, and a filter dust collecting part 3 in which the fine particles separated and removed by the hopper 2 are carried on an air stream to suck and collect them in a filter chamber 17 and are filtered and separated there and are recovered in a fine powder recovery hopper 18 are combined to constitute a sand producing device.

摘要： PURPOSE:To make foreign matter mixed in a material to be pneumatically screened fall by gravity to effectively remove it by feeding the material to be pneumatically screened into a fluidized bed chamber and fluidizing the material to be pneumatically screened by compressed air introduced from an air blasting chamber through a filter. CONSTITUTION:A material to be pneumatically screened 30 is fed from a feeding port 14 for the material 30 into a fluidized bed chamber 12. Inside the fluidized bed chamber 12, by compressed air introduced from an air blasting chamber 11 through a filter 20, the material to be pneumatically screened 30 is fluidized. In this way, mixed foreign matter 31 contained in the material to be pneumatically screened 30 is freely transferred and is made to fall by gravity to deposit it on the filter 20. At this time, in case the mixed foreign matter 31 is magnetic body metal powder, it is attracted and collected by a magnet 22 during the falling. And inside the fluidized bed chamber 12, the movement of the material to be pneumatically screened 30 and the foreign matter 31 is obstructed by a partition plate 21. As a result, the material to be pneumatically screened 30 or the like is not immediately discharged from a discharge port 15 for the material 30 and stays in the screen for a fixed time.

摘要： PURPOSE:To make it possible to select unpolished rice from waste rice in an optimal condition with the adjustment of a wind power through the naked eye over the discernment of a floating state of waste rice and the shaking state of unpolished rice by making the wind power variable selecting between the adjustment of the number of rotations of a wind mill and the adjustment of a suction port in a wind tunnel. CONSTITUTION:A selection device to select unpolished rice from waste rice is composed of a wind mill 3 housed in a fixed case 1, and further, a wind tunnel 2, a shaking frame 12, a selection net 18, an elevator 31 to supply waste rice and a shaking mechanism to shake back and forth the selection net 18 in a right/left skew vertical direction. In addition, the selection net 18 is nearly square and consists of a lateral direction on a feed side 19 and a discharge side 20, and a horizontal direction on a shake-up side and a shake-down side. The feed side 19 is higher gradient than the discharge side 20 and the shake-up side is higher gradient than the shake-down side. The discharge side 20, equipped with a divider, forms an unpolished rice delivery port on the shake-up side, a waste rice delivery port on the shake-up side and an intermediate rice delivery port on an intermediate part. In this way, the wind power of the wind mill 3 is made variable by adjusting either the number of rotations 3 of the wind mill or the suction port 4 of the wind tunnel 2.

摘要： PURPOSE:To classify a material to be classified into a coarse powder and a fine powder by blowing up the material to be classified falling from a feeder toward an air exhaust port by a dispersing rotor to disperse the same, and allowing the coarse powder to fall to discharge the same from a coarse powder discharge port while discharging the fine powder from the air exhaust port along with an air stream. CONSTITUTION:The material to be classified supplied by a rotary feeder 3 is in a flocculated state but falls almost vertically as shown by an arrow A to be blown up toward an air exhaust port 6 by a dispersing rotor 4 to be dispersed. The fine powder in the material to be classified dispersed by the dispersing rotor 4 is carried to a fine powder classifying chamber 5 by an air stream, as shown by an arrow C, and discharged from the air exhaust port 6 along with the air stream. The coarse powder in the material to be classified falls almost vertically against the air stream under its own wt., as shown by an arrow D, to be discharged from a coarse powder discharge port 62.
