PROBLEM TO BE SOLVED: To provide a material burning device and a material burning method capable of accurately controlling a material input amount from a preheating furnace to a rotating furnace. SOLUTION: A material cut out from a material storage layer 4 is supplied to a material storage distribution part 10 provided in the preheating furnace 9, and the material distributed by the material storage distribution part 10 is accumulated in a rotated hearth 11 for primary burning. The material primarily burned is dropped down to a discharge hole 16 by a plurality of pushers 17, and thus, the material is inputted in a rotary kiln 20 for secondary burning. At this time, the material of a target input amount to the rotary kiln 20 is cut out from the material storage layer 4. A material level in the material storage distribution part 10 is detected by an ultrasonic level measuring device 54, and control is performed so that the detected material level is kept in a predetermined range. Based on the level variation of the material level in the material storage distribution part 10, drive intervals of the pushers 17 are controlled so as to perform the quantitative control of the material input amount to the rotary kiln 20.
