摘要： PROBLEM TO BE SOLVED: To solve the problem where a coarse aggregate cannot be blended with an unshaped refractory in an industrial scale since a continuous-type kneading mixer for blending the coarse aggregate with the unshaped refractory has not been considered at all. SOLUTION: A continuous-type kneading mixer 3 is equipped with conveyance kneading, dispersion mixing, and ejection parts 7, 8, and 9. At the conveyance kneading part 7, the unshaped refractory is carried while being kneaded for changing into sol. At the dispersion mixing part 8, in the unshaped refractory being changed into the sol, a turning flow generation blade 19 that has an external diameter for forming space where the coarse aggregate can be turned around a rotary shaft 11, and a conveyance kneading member 13 that carries the unshaped refractory being changed into the sol where the coarse aggregate is dispersed for blending are fitted onto the outer- periphery surface of the rotary shaft 11, at the same time, a fall-throwing device 16 of the coarse aggregate is provided, and the coarse aggregate is nearly uniformly dispersed to the unshaped refractory being changed into the sol for mixing. At the ejection part 9, the unshaped refractory being changed into the sol where the coarse aggregate is dispersed for mixing is allowed to fall into a mold for throwing via a slanting surface 9a.
