METHOD OF REGULATING WATER CONTENT OF MATERIAL

WIPO Patent Application WO/2006/104227

A1

A method of water content regulation by adding a liquid such as water to a raw material such as a powder material, e.g., bentonite. By the method, a liquid such as water can be evenly mixed with the raw material with a relatively simple equipment. The water content of the raw material used in a large amount can be easily regulated. Due to the even water content regulation, a material having satisfactory water-barrier performance, etc. can be obtained. In a stirring tank (1) which is an ordinary powder mixer kept at a low temperature, powdery bentonite (A) is mixed with finely particulate ice (B) by stirring. Namely, the two powders are mixed together by stirring. Thus, the powdery bentonite (A) is evenly mixed with the finely particulate ice (B) to obtain bentonite regulated so as to have an even water content. The stirring tank (1) is connected to, e.g., a liquid-nitrogen bomb (21) and the inside of the stirring tank is kept at a low temperature with the nitrogen gas supplied from the bomb. The finely particulate ice (B) prepared beforehand is introduced through an introduction opening (20).
