After being dried in a drying oven (8), it is ignited in an ignition oven (9), and an air exhaust fan (IQ) sucks the atmosphere through the green pellets, thereby burning and cooling the green pellets. ) The pellets are discharged from the ore discharge section of the pallet group (3).In this conventional production method, the exhaust fan (to) is used to uniformly remove -40
Because a negative pressure of about 0-"Al is applied, too much air passes through the upper layer of the raw pellet at the initial stage of ignition, and the upper layer is not fired at a sufficient firing temperature, resulting in low-quality, low-strength On the other hand, after the upper layer of the green pellet has been sufficiently fired, the lower layer of the green pellet is preheated by the high heat of the upper layer, so it is not necessary to apply high negative pressure. However, this is not done and no attempt is made to shorten the firing time.

せることができるものである。Therefore, the present invention provides a method for producing artificial aggregate that solves these problems, and its features are as follows:
The green pellets are fed onto the feeding section of the endless pallet group that moves in one direction of the Dwight Lloyd type calciner, and after drying the green pellets in a drying oven, the green pellets are heated under a low negative pressure. After igniting the raw pellets in a furnace and allowing the upper layer of the raw pellets to burn sufficiently, high negative pressure is applied to the raw pellets (3). According to this method, the raw pellets are Not much air passes through the upper layer, and the upper part is fired at a sufficient firing temperature. Therefore, it is possible to produce high-quality artificial aggregate with high strength. Further, after the upper layer of the green pellet has been sufficiently baked, a high negative pressure is applied to the green pellet, so the baking cooling time can be shortened and productivity can be improved.

産性を向上させることができるものである。As described above, according to the method for producing artificial aggregate of the present invention, at the initial stage of ignition, the atmosphere does not pass through the T-layer portion of the green pellet much, and the upper layer portion is fired at a sufficient firing temperature. Therefore, it is possible to produce high-quality artificial aggregate with high strength. In addition, after the upper layer of the green pellet has been sufficiently burned, high negative pressure is applied to the green pellet, so the burning and cooling time can be shortened and productivity (5) can be improved. It is something.
