摘要： PURPOSE:To obtain a ceramic foam and to utilize waste as resources by forming a massive glass by melting the waste such as municipal waste or sludge, cooling, solidifying and next, feeding the massive glass into a high temp. furnace, thereby firing and foaming the glass. CONSTITUTION:The glass is formed by melting the waste such as municipal waste or sludge, cooling and solidifying it. A particulate having adequate particle diameter is formed by pulverizing the glass and is granulated to form a granular body having an adequate particle diameter after a molding material and a firing-foaming material are added into the particulate. Next, the granular body is fired and foamed by feeding it into the high temp. furnace. Excellent foaming property is attained by applying a coating material such as clay on the surface of the coarse pulverized granular body.

摘要： PURPOSE:To obtain raw material glass useful as a ceramic raw material at a low cost by adding a regulating material to a waste such as municipal waste or sewage sludge, subjecting the resultant mixture to the melting treatment, then cooling the melt, forming low-melting glass and pulverizing the prepared glass to a suitable particle size. CONSTITUTION:A regulating material is added to a waste such as municipal waste, sewage sludge, fly ash, mine pulverized waste, river deposit or lake and marsh sludge. Phosphoric acid, boric acid, silicic acid, aluminic acid and ores, oxides, compounds of the acids, etc., are used as the regulating material. The waste is then preferably subjected to the melting treatment in a reducing atmosphere to produce a regulated molten stag, which is subsequently cooled and solidified to form low-melting glass having prescribed performances. The resultant low-melting glass is further pulverized to a suitable particle size to produce raw material glass as a ceramic raw material. Since the resultant raw material glass has a low melting point, a forming base material can be sintered at the low temperature when the raw material glass is mixed in the forming base material. Thereby, a low-temperature ceramic sintered compact having both low water absorptivity and shrinkage factor can be obtained.

摘要： PURPOSE:To make urban waste refuse incineration ash harmless so as not to generate environmental pollution and to inexpensively obtain a ceramic raw material by melting urban waste refuse incineration ash under heating and grinding slag obtained by cooling the molten ash. CONSTITUTION:Urban waste refuse incineration ash is melted under heating and the molten ash is cooled to form slag which is, in turn, ground to obtain a material capable of being utilized as glaze for pottery or a ceramic raw material. For example, slag obtained by cooling molten urban waste refuse incineration ash heated to 1450 deg.C is finely ground and 5-10% of bentonite is added to the ground slag to adjust the moisture thereof to 6% and this slag is subjected to press molding so as to have a predetermined size and the molded one is dried and subsequently fired at 1000 deg.C to obtain a cream color ceramic plate reduced in contraction and moisture absorption. As the urban waste refuse incineration ash, one mixed with waste such as sewerage sludge can be used.

摘要： PROBLEM TO BE SOLVED: To provide a system for manufacturing sand capable of recovering a useful metal from a crushed slug of waste melting slug maked from a shredder dust and an industrial waste as a material and obtaining a crushed slag suitable for construction aggregate and ceramics material. SOLUTION: The crushed slag 111 is formed by crushing/treating a water crushed slag 111 in a slag crusher 114. Metal particles having an excellent ductility such as aluminum are formed to a thin piece having a large diameter by rolling treatment. The thin piece of aluminum is separated/recovered by a classification by a sieve 113. The crushed slag after the sieving 113 is subjected to a specific gravity separation treatment by a specific gravity separation device 115 to separately recover other metal particles 116. The crushed slag of the remaining slag particles is recovered as a product sand 118. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To improve separation efficiency by a method in which a mixture agitated by the rotation of a cylinder is separated into an upper part and a lower part correspondingly to the difference in specific gravity a substance of larger specific gravity is released from an opening on the front side by a spiral projected stripe, and a substance of smaller specific gravity is released from an opening on the rear side along the inclination in the bottom surface of the cylinder. SOLUTION: While a cylinder 10 is rotated in the fixed direction X by driving a motor 5, a mixture (a) comprising at least two components having different values of specific gravity is supplied into a hopper 32 to be charged from a charge pipe 33 into the front part 11 of the cylinder 10, the mixture (a) is agitated, a substance of larger specific gravity is separated to a lower layer, and a substance of smaller specific gravity is separated to an upper layer. The substance of larger specific gravity is passed between an outer pipe 15 and an inner pipe 28 from an opening 13 on the front side by a screw conveyer by the rotation of a spiral projected stripe 20 and dropped from the discharge cylinder 27 of a housing 25 into a tank 30. The substance of smaller specific gravity is conveyed by a screw conveyer by the rotation of another spiral projected stripe 21 and dropped from an opening 14 on the rear side into another tank 31.
