PURPOSE:To fully develop characteristics inherent to a fine powder in use by improving workability during transport and storage, by preliminarily solidifying the fine powder for industrial use so as to reduce the volume thereof by pressing said fine powder before breaking up the same at the time of use. CONSTITUTION:In storing and transporting a fine powder material, said powder material is solidified so as to reduce the volume thereof by pressing the same by using a proper press molding apparatus. Or, a molding aid and a breaking-up aid are added to the fine powder to solidify the same under pressure so as to reduce the volume thereof. This molded body is broken up by using a general pulverizing machine at the time of utilization. By this method, transport and storage become convenient and the problem of environmental pollution by dust can be eliminated.
