Filed: 1983-05-09
Abstract: PURPOSE:To inexpensively and efficiently dispose fly ash such as cinders produced in a coal power plant, by sintering unsintered fly ashes placed on sintered fly ashes. CONSTITUTION:After fly ashes, such as cinders produced in a coal power plant, ashes collected by a dust collector, are previously formed, the fly ashes placed on sintered fly ashes is sintered at, for example, 900-1,350 deg.C, or the fly ashes, not being formed, are placed on the sintered fly ashes as they are and are sintered.

Then by rotating in an opposite direction from the primary position, an ejection mechanism 20 ejects a second card 100B loaded within a second slot 2B. Consequently, even when an ejection error is generated in the middle of the ejecting operation of the card of one side 100, the pin 7 is made to recur to the primary position without giving influence to the card of the other side 100 which is not an ejecting object. In addition the ejection mechanism 20 is functioned mainly by a pressing movement plate 5, the output gear 6d with the pin 7 and a slot 2.
