PURPOSE: To heat and crush a material at low investment and running cost by forming a fluidized bed with a hot gas, introducing a raw material from above the fluidized bed, heating and crushing the material below the bed and discharging the crushed material.
CONSTITUTION: A vessel 10 includes the upper part of an inverted trunkated cone with the bottom opened above a horizontal roller mill 11. The mill 11 includes the cylindrical housing 12 and solid base 13 on a prince, and the upper end of the housing wall 12 is connected to the lower end of the conical part of the vessel 10 through a connecting ring 14, A taper crushing roller 15 is provided in the mill 11, and further the roller 15 cooperates with a rotary crushing table 17. Further, a burner tube 20 is extended from the lid 21 of the vessel 10, divided into two tubes at the lower part, allowed to bestride the pressure spring 16 midway and extended to the table 17. Subsequently, when the raw material is ignited by the burner and supplied, the raw material is fluidized by a gas from the burner tube 21, further self-fluidized by the steam generated from the burned raw material, crushed at the lower part and discharged from a weir 28.
