摘要： PROBLEM TO BE SOLVED: To efficiently separate the granule free from a pollutant and large in particle size while adding water from the granule subjected to granulating treatment and to which the pollutant is stuck. SOLUTION: The granule to which a pollutant is stuck is subjected to crushing/deflocculating treatment by the primary granulating machine 21 and the secondary granulating machine 23 provided with a cylindrical rotary drum having plural outer blades on the inner peripheral surface and a rotor having plural inner blades on the outer peripheral surface and eccentrically mounted at the inside of the rotary drum. Thereafter, the granule having large particle size and free from a pollutant is separated from the granulated granule by using a negative pressure type liq. cyclone 51 provided with a spigot nozzle composed of an elastic body mounted to a material discharge pipe provided at the bottom part of the cylindrical main body.

摘要： PROBLEM TO BE SOLVED: To scale down an ash melting equipment and to reduce the treating cost by reducing the volume of the incineration ash to be melted and solidified and to simplify the equipment for reducing the volume of the incineration ash. SOLUTION: A fitting force is exerted on a granular body in the incineration ash by using two milling devices 30 and 50 to finely granulate the granular body. The fine grain containing a large amount of a harmful material such as heavy metal and dioxin is separated from the finely granulated granular body in process water, then the unburned coarse grain and unburned fine grain in the ash are respectively made harmless and extracted by using vibrating screens 40 and 60, a dehydrated cake is formed from a slurry containing the fine grain of the remaining harmful material, and the dehydrated cake is dried in a drying furnace 81, charged into a melting furnace 82, melted and solidified.

SOLUTION: Two finely granulating apparatuses 20, 40 are installed and the width of a groove of an inner blade of the secondarily granulating apparatus 40 is made narrower than that of a groove of an inner blade of the primarily granulating apparatus 20. Further, the rotor diameter of the secondarily granulating apparatus 40 is made wider than that of primarily granulating apparatus 20 to carry out pulverization of a treatment material mainly in the primarily granulating apparatus 20 and deflocculation in the secondarily granulating apparatus 40.

摘要： PROBLEM TO BE SOLVED: To miniaturize the scale of ash melting facilities and lower the treatment cost by efficiently decreasing the volume of incinerator ashes to be melted and solidified. SOLUTION: After ultra small incombustible substances with a prescribed particle size in which a large quantity of harmful substances such as heavy metals and dioxins are contained are previously separated, the incinerator ashes from which the ultra small incombustible substances are separated are abraded and pulverized and granules in the incinerator ashes are finely granulated and at the same time the superfine particles containing a large quantity of harmful substances such as heavy metals and dioxins are separated in water and then coarse incombustible substances and finely granular non-combustible substances in the incinerator ashes are respectively detoxicated and extracted. The resulting slurry of the remaining ultra fine particles of the harmful substances are dewatered to produce a dewatered cake and then the dewatered cake and the ultra small incombustible substances are melted and solidified together.
