Material moisture content adjustment method

摘要: When making moisture content adjustment by adding liquid such as water to a raw material pulverulent including bentonite, uniform mixing of the with is given relatively simple facilities, large quantity materials attainable, and besides, having satisfactory performances impermeability obtainable through adjustment. Within tank ( 1 ) configured normal powder mixer kept at low temperatures, bentonite (A) fine granular ice (B) are stirred mixed. Stirring fellow adapted uniformly mix (B), enabling content-adjusted be obtained. A liquid-nitrogen gas bomb 21 ), for instance, connected causing inside temperatures nitrogen supplied from bomb, before putting prepared an inlet port 20 ).
