The applicant of the present application has developed a rotary crushing and mixing method for improving and effectively utilizing construction soil and the like, and a rotary crushing and mixing apparatus used in this method, and obtained a number of patents other than Patent Documents 1 to 7.

The rotary crushing and mixing method uses a rotary crushing and mixing apparatus equipped with a belt-type impact member member (hereinafter referred to as an impact member) rotating at a high speed in a cylindrical container, and is used for crushing a construction- This method has the effect of dispersing the material finely and homogeneously. In addition, if necessary, the properties and strength of the modified soil can be adjusted by mixing cement fireproofing such as burnt lime and slaked lime, cement fireproofing such as ordinary cement or blast furnace cement, or soil improvement material made of a polymer material.

This rotary crushing mixed method has a wider application range of gypsum than the conventional gypsum method, so that it is possible to homogeneously mix gypsum which was difficult to be improved by the conventional method. That is, the clay loose is finely loosened by the impact force of the belt-shaped impact member member rotating at a high speed, and the soft rock is finely crushed to be mixed, so that the soil can be produced with stable quality. As a result, up to now, the effective use of construction sites and the like, which have been disposed of over the long term, can be achieved, and the environmental load can be reduced, and the cost of the construction expense can be reduced.

In this way, the rotary crushing and mixing method can perform crushing and mixing at the same time with one mechanism, and it is suitable for the effective use of the construction earth because it adapts to a wide range of tofu constructions ranging from thick rock to soft rock.

Basically, the setting condition or the operating condition is automatically determined by inputting the target quality of the modified soil or the information of the raw soil material. The position and the number of the impact members are adjusted according to the setting conditions, and instructions are given about the operation control of the rotary crushing mixer and the peripheral equipment.

Table 1 shows the relationship between the target quality of the modified soil, the information of the raw soil material, and the setting conditions in a simplified manner. Items represent only typical items in terms of explanation and paper size. In practice, more efficient control can be performed as the number of items increases.
