First, FIG. 1 is a concrete form of the first invention of this application. In this embodiment, several types of papermaking sludges having different water contents are mixed in the first step, and sawdust, etc. The additives are mixed and kneaded by using a mixer (1) or the like so as to obtain a homogeneous state. In this case, since sawdust is added to the papermaking sludge, even if the papermaking sludge itself is a fibrous material that is easily entangled, the papermaking sludge is separated without being entangled due to the interposition of sawdust. As a result, the kneaded product is easily formed into particles. As the sawdust, it is advisable to employ one that is produced secondarily from a factory that uses wood as a raw material, such as a sawmill. As the papermaking sludge, it is desirable to knead various materials having different water contents discharged from a paper manufacturing plant or the like to prepare a kneaded product having a water content of about 65%. Further, for stirring and kneading, iron balls or the like may be used to carry out stirring and kneading by utilizing the principle of a ball mill.

In this way, the granular kneaded material that is homogenized by stirring and kneading to adjust the water content has sawdust added, and therefore is further extruded through the extruder (2) in the next step and extruded through the extrusion port, and then the next step. In the process, it is put into a granulating machine (3) such as a tumbling type, an extrusion molding type or a crushing type, and tumbled, extruded or crushed to easily separate and solidify into particles. And
As a result, granular materials are efficiently formed. This granular material has a water content of about 30 to 40% and a size of about 1 to 10 mm.
