摘要： PURPOSE:To produce a fine-grain lightweight aggregate by providing a lifter for rolling a raw material in the softened zone on the surface of the granulating raw material, using the hardly abrading raw material and covering the raw material surface with a fusion preventive material in the calcination zone where the surface of the grain is softened. CONSTITUTION:The granulating raw material is crushed by a ball mill to the powder having =15% by regulating a caking agent and water. A line of lifters 3 is mounted at least in the raw material softening region A of the calcination zone in a rotary kiln 1 in every 1-1.5m length of the inner peripheral refractory wall, and the raw material 4 in the kiln 1 is uniformly heated by means of the lifter 3. A fusion preventive agent 5 is sprayed from a feed pipe 7 along with compressed air into the range from 1/3 of the length A on the upsrteam side to 1/3 on the downstream side with the upstream side of the region A as the center.

摘要： PROBLEM TO BE SOLVED: To simply regenerate and produce a high-quality coarse aggregate slight in attached cement paste, by grinding a concrete waste into a specific size, classifying the ground particles, recovering a coarse aggregate and a fine aggregate having specific particle diameters, respectively, abrading particles having particle diameters smaller than a specific particle diameter, redispersing the particles, screening particles having a specific particle diameter or larger than it by specific gravity and recovering particles having a prescribed specific gravity as the fine aggregate. SOLUTION: A concrete waste is ground into particles in the size of about 0.8-1.2 times as much as the maximum diameter of the aggregate contained in the waste by using, for example, a jaw crusher. The crushed material is classified, for example, by a vibrating screen and particles having >=5 mm particle diameter are recovered as a coarse aggregate and particles having 0.6 mm to =.15 mm particle diameter are selected by gravity by using a gravity classifier preferably set in a settling chamber and particles having >=2.3 specific gravity are recovered as the fine aggregate.

摘要： PROBLEM TO BE SOLVED: To utilize a large amt. of spent concrete fine powder without lowering the strength as a low-heat hydraulic material by using a spent concrete fine powder and a blast-furnace slag fine powder as the main components of the material, incorporating a cement fine powder and/or gypsum into the material to constitute the hydraulic material and specifying the fineness of the material. SOLUTION: The spent concrete fine powder obtained by processing a fine grain generated when spent concrete is regenerated and with the fineness controlled preferably to >=5000cm /g Blaine value and the blast-furnace slag fine powder with the fineness adjusted favorably to >=10000cm /g Blaine value are used as the main components of the material, and cement fine powder and/or gypsum are incorporated into the material to constitute a hydraulic material. In this case, the fineness of the hydraulic material is controlled to >=8500cm /g Blaine value. Further, 60-80wt.% spent concrete fine powder, 14-38% blast- furnace slag fine powder, 1-12% cement fine powder or 2-6% gypsum, expressed in terms of anhydrous gypsum, are preferably incorporated into the material.

摘要： PURPOSE:To reduce the pressure loss of the whole of a classifier to a large extent as compared with a conventional example by setting the length of a rotor blade in the radius direction of a rotor to predetermined times the difference between the radius of the outer periphery of the rotor blade and that of the exhaust port of a rotor chamber. CONSTITUTION:A vortex stream type air classifier is equipped with a rotor chamber RT having an inlet IN and an exhaust port 30, a plurality of rotor blades 6 provided to the inlet IN of the rotor chamber so as to leave an interval in the circumferential direction of a rotor 5 and the classifying chamber 7 provided to the outer periphery of the inelt IN of the rotor chamber. The length Bw in the radius direction of the rotor of each of the rotor blades 6 is set to 0.7-1.0 times the difference between the radius R1 of the outer periphery of each of the rotor blades and the radius Ro of the exhaust port of the rotor chamber. By this constitution, the fluid flowing in the inlet IN of the rotor chamber from the classifying chamber 7 passes through the rotor chamber in the contact state with the rotor blades 6 to be discharged out of the exahsut port 30 of the rotor chamber and, at this time, the fluid in the rotor chamber RT become a forcible vortex without forming a Burger's vortex.
