The present invention, when gypsum particles derived from waste gypsum boards are calcined using a hot-air rotary calcinator, makes the calcined gypsum particles have a reduced gypsum dihydrate content. Gypsum particles obtained by crushing waste gypsum boards and made of gypsum dihydrate are calcined. The gypsum particles are supplied to a cylindrical rotating tank, and the gypsum particles are stirred by the rotation of the tank. Hot air is supplied to a pipe positioned at the axial-direction center of the tank and provided with a plurality of nozzles, and is blown from the nozzles into the gypsum particles, thereby converting the gypsum dihydrate in the gypsum particles into gypsum hemihydrate and/or III-form anhydrous gypsum. The peripheral speed of the inner wall of the rotating tank is in the range of 2-10 m/min.

The present invention prevents powder/granular material from falling from a gap between a bucket and a casing-side discharge port of a conveyor when powder/granular material of low specific gravity is conveyed by a vertical circulation bucket conveyor. The vertical circulation bucket conveyor, in which a plurality of buckets are fixed to a chain and vertically circulated, conveys the powder and granular material vertically between a loading port and a discharge port provided in a casing of the bucket conveyor. A plate projecting from the discharge port toward the buckets is detachably attached to at least the discharge port so that the buckets intermittently come into contact with the plate. As a result, the gap between the discharge port and the buckets is reduced, and the powder/granular material accumulated on the plate is swept off toward the discharge port by the impact caused by the contact between the buckets and the plate.

The present invention improves the resistivity value of a polysilicon rod precipitated at an early stage of a growth period while preventing collapse of the polysilicon rod at the early stage of the growth period. This method for producing a polysilicon rod (S1) involves supplying a raw material gas (G1) containing a chlorosilane to a silicon core wire erected in the inside of a reaction furnace (10) and obtained by performing electrical-heating, thereby precipitating polysilicon to the surface of the silicon core wire and growing the same into a polysilicon rod (S1) having a diameter of 80 mm or more. The raw material gas (G1) is introduced into the reaction furnace (10) in a manner that the number of gas exchange representing the introduction amount of the raw material gas (G1) into the reaction furnace (10) with respect to the volume of the reaction furnace (10), in a growth start period (T1) of the polysilicon rod (S1) until one hour passes from the start of precipitation of the polysilicon to the surface of the silicon core wire, is not less than 8 times but less than 35 times.
