Patent number: 5935618Abstract: An apparatus for manufacturing molded materials solidified by sulfur includes an apparatus for bringing the water content of a solid raw material to be mixed with sulfur, such as slag and dust resulting from steel-making, to 3% by weight or below, an apparatus for heating and kneading the mixture of raw materials including molten sulfur at 119 to 159.degree. C., to cause the sulfur to penetrate into pore spaces on the solid raw material, thereby preparing a fluid kneaded mixture, and an apparatus for molding the mixture into a prescribed shape. Utilizing the apparatus, slag and dust resulting from steel-making, etc. is solidified with a melted sulfur thereby, enabling solidified and molded materials to be produced industrially, while preventing the generation of sulfurous acid gas. The materials' performance, such as physical strength and quality, are constant and high, and harmful heavy metals or the like will not ooze out of the materials.Type: GrantFiled: June 19, 1997Date of Patent: August 10, 1999Assignees: Ikari-Laboratory for Environmental Science Co., Ltd., Nishida Mining Co., Ltd., Tanaka Iron Works Co., Ltd.Inventors: Yoshikatsu Ikari, Chujiro Nishida, Katsuyoshi Toyofuku, Toshiyuki Kokubu
