摘要： PROBLEM TO BE SOLVED: To provide a producing method of a particulate compd. by which the particulate compd. having a uniform particle size can be obtd. by the reaction of two or more kinds of compds. and the particle size can be easily controlled. SOLUTION: Two kinds of compds. which react with each other by heating while producing a gas, for example, a silicon-contg. compd. and a carbon-contg. compd. are reacted by calcining them in an inert atmosphere to produce the particulate objective compd., preferably silicon carbide. In this process, the amt. of the gas produced during calcination is detected and the calcination temp. is raised or decreased according to the detected amt. to control the particle size of the particles of the objective compd. Preferably, the average particle size of particulate silicon carbide obtd. by the reaction of the silicon-contg. compd. and the carbon-contg. compd. ranges from 0.1 μm to 10 μm, and the ratio (D90O/D10) of the diameter at 90% accumulation (D90) to the diameter at 10% accumulation (D10) calculated from the grain size distribution is

摘要： PROBLEM TO BE SOLVED: To continuously prepare a molecular sieve and to control both the particle size and the particle size distribution. SOLUTION: The molecular sieve expressed by the experimental formula: rR2O: (SixAlyPz) (R represents at least one of a template agent, each of 'r', 'x', 'y' and 'z' represents respectively the molar ratio of R, Si, Al and P), in inorganic base is continuously synthesized by continuously adding reactive supply sources of desired components with a structural indicator in a continuous crystallization reactor to reversely mix between stages or to adjust the number of the stages to control the particle size. As a preferable method for controlling the particle size distribution, the product is divided into two flows, each flow is fed in a wet pulverizing device operated in respective different intensities and after that, mixed with each other to obtain a distribution having at least two modes.

摘要： PROBLEM TO BE SOLVED: To stably obtain coarse ammonium sulfate crystal by catching the existing quantity or the existing ratio of a crystal having a certain particle diameter to exist in the crystallization kettle and to flow-in an outer circulating line and controlling the value thereof. SOLUTION: An existing quantity or an existing ratio of a crystal (primary nucleus, secondary nucleus and fine crystal) having the particle diameter to exist in a crystallization kettle and to flow in a outer circulating line is obtained by a measured result of the particle size by a particle diameter distribution measuring device or the like provided in the kettle. Alternatively, the quantity or the ratio is obtained by the result of measuring the particle diameter distribution or the slurry concentration by a particle diameter distribution measuring device or a slurry concentration detector provided in the outer circulating line. In such a case, when the existing quantity or the existing ratio of the crystal is increased, only the excess fine crystals are eliminated by intermittently or continuously supplying water in the outer circulating line. Further, the existing quantity or the existing ratio of the crystals in the kettle is controlled by changing the stirring speed of a stirrer provided in the kettle and when the quantity of the secondary nuclei or the fine crystals is increased, the stirring speed is reduced.

摘要： PROBLEM TO BE SOLVED: To produce a granulated matter having a specified particle size distribution with a high accuracy by irradiating a granulated matter under growth in the process of manufacturing the granulated matter with a light beam, sampling diffracted/ scattered light so as to calculate particle size distribution at this moment and comparing the particle size distribution with a target value so as to control growth factors of particles according to result of comparison. SOLUTION: When a granulated matter is produced, in the first place a powder material is placed on a fluidized bed 6 and heated air is fed into the fluidized bed 2 through a feed port 2h so as to fluidize the powder material on the fluidized bed 6 for mixing the powder material. A bonding medium solution is sprayed from a nozzle means 7 so as to flocculate and dry the powder material for growth of particles. During this process a laser beam is irradiated by a measurement cell of a sample measuring device 3 at a predetermined interval and diffracted/scattered light from particles is detected by a photodetector and measurement data is analyzed so as to calculate particle size distribution data. The particle size distribution data is compared with target data and particle growth factors such as temperature of heated air, wind volume, spray amount and the like are controlled on the basis of result of comparison.
