Method and apparatus for producing lightweight solidified material, pipe-type mixer apparatus, apparatus for producing solidifying material, and gravity adjusting apparatus

摘要

The invention provides a technique which is effective for reusing a hydrated fluid waste product or the like. A fluid raw material containing a water content and a solid content is changed to a lightweight solidifying material while being carried to a destination place, by adding or removing the water content by a gravity adjusting apparatus ( 1 ) so as to adjust gravity, next adding and mixing a solidifying material by means of a first pipe-type mixer ( 4 ), and next adding and mixing a lightening material by means of a second pipe-type mixer ( 5 ).
