摘要： PROBLEM TO BE SOLVED: To produce a high-quality inexpensive coal ash granulated material by combining industrial wastes each having a low rate of utilization. SOLUTION: Electric furnace reduction slag is added to coal ash by 10-100% of the mass of the coal ash and a mixture is prepared in a mixer 1, sent to a mixing-kneading machine 3 through a stock hopper 2, kneaded with water and granulated with a granulator 5 to produce the objective coal ash granulated material. Strength is exhibited by comminuting the electric furnace reduction slag to a particle diameter equal to that of the coal ash before addition to the coat ash, and the production of the coal ash granulated material is facilitated by adding 1-5% bentonite based on the amount of the coal ash to the mixture.

摘要： PROBLEM TO BE SOLVED: To obtain a method for crystallizing waste and harmful matters, which increases applications of waste and harmful matters by controlling so that a melt treated matter is crystallized in a desired state in a melt treatment of waste and harmful matters. SOLUTION: In this crystallization method, 0.1-10 mass % of alumina powder is mixed with waste and harmful matter. The mixture is heated up to a melting point higher at least by 200 deg.C than a melt flow point, after the melting, the mixture is held in a temperature range lower by 100 deg.C than the softening point, or lower by 150-200 deg.C than the softening point at least for one hour. By this process, crystallization of the melt treated matters of waste and harmful matters is controlled, while the viscosity is being lowered, the homogenization of the whole matter is attained to promote the crystallization, accordingly an appropriate classification is made in the production as aggregates and special stones for the waste and harmful matters.

摘要： PROBLEM TO BE SOLVED: To improve the productivity in manufacturing artificial lightweight aggregate by preventing cohesion of aggregate particles themselves, that of aggregate particles to the shell surface of rotary kiln, and preventing interruption of firing by rough surface formed by adhesion of aggregate particles to the shell surface, which are caused by the presence of fine particles of raw aggregate. SOLUTION: The method uses a rotary kiln 2 to manufacture artificial lightweight aggregate, which contains drying, sintering, and bloating processes of raw aggregate and additionally a process to remove fine particles of raw aggregate from the kiln 2 before they reach the bloating temperature. Removing of fine particles is preferably implemented in a range where aggregate shows a dropping strength of >=85% of that of sintered aggregate or a crushing strength of >=10 kgf. Fine particles are removable to outside from the kiln by using a heat-resistant screen at the middle of kiln 2 or at connecting positions of a plurality of rotary kilns 11, 12, 13.
