摘要： Provided is a conveyor such that, after stopping or restricting supply of granular material to a downstream device, it is possible to restart normal operation of conveying the granular material without delay. This conveyor includes: a casing having a conveying path of a granular material therein and having a discharge port for discharging the granular material to a downstream device; a plurality of conveying units accommodated in the casing and configured to convey the granular material to the discharge port by circulating along the conveying path; an opening/closing mechanism that opens and closes the discharge port; and a control unit that controls operation of the plurality of conveying units and the opening/closing mechanism. When restricting supply of the granular material to the downstream device, the control unit controls the opening/closing mechanism to close the discharge port, and continues to circulate the plurality of conveying units, thereby continuing to move the granular material along the conveying path.

摘要： Provided is a water-absorbing resin that exhibits excellent absorption performance and a high permeation rate with respect to liquids to be absorbed, and that effectively reduces liquid leakages, even in an absorbent body using a large amount of the water-absorbing resin. The water-absorbing resin is formed from a polymer of a water-soluble ethylenically unsaturated monomer, and when a cross-sectional image of the water-absorbing resin obtained by X-ray computer tomography is observed, the ratio (cavity area ratio) as calculated by formula (I) of the area of cavity portions in the cross-sectional image is 2-10%. The liquid flow rate index as calculated by formula (II) when a physiological saline liquid column flow rate test is performed on the water-absorbent resin having a particle diameter of 250 to 500 μm at 37° C. is 5-20. (I) Cavity area ratio [%]={total cross-sectional area (B) of cavity portions in the water-absorbing resin/(total cross-sectional area (A) of resin portions in the water-absorbing resin+total cross-sectional area (B) of cavity portions in the water-absorbing resin)×100} (II) Liquid flow rate index={liquid flow rate (CPR2) during 10 second period between 50 seconds and 60 seconds after initiation of liquid flow/liquid flow rate (CPR1) during 10 second period after initiation of liquid flow}×100
