| A method and apparatus are provided to process collected sand. This method and apparatus allow the moisture content to be adjusted and the addition of a binder to be facilitated to renew the collected sand as casting sand for future use. Also, defective castings are prevented when they are made by a main mold using the renewed casting sand. The sand-collecting means can be compact. The method is performed and the apparatus is operated by separating a main mold of green sand, after casting is conducted, into parts unaffected and affected by the molten metal heat, adjusting the moisture content of the part unaffected by molten metal heat for use as facing sand in the next main mold making, and adding a binder and adjusting the moisture content of the part affected by the molten metal heat for use as back sand in making the next main mold. | ||||||
| 60 | Apparatus for heat treating a particulate material | US134529 | 1993-10-08 | US5382002A | 1995-01-17 | Marvin Evans; David H. Miller |
| An apparatus for heat treating particulate material containing a combustible contaminant. The particulate material is fed into the upstream end of a rotary drum and is conveyed toward the downstream end of the drum. A fixed first tubular member is disposed concentrically within the downstream end of the drum and includes a small diameter inlet section and a larger diameter outlet section. A fuel burner is located within the small diameter end of the first tubular member and combustion gases from the burner travel through the first tubular member to the larger diameter outlet section where the gases expand and are cooled. The gases are then discharged into the upstream end of the drum into contact with the particulate material to vaporize the combustible contaminants. A second tubular member is mounted in radially spaced relation between the first tubular member and the downstream end of the drum to provide inner and outer annular chambers. The vaporized contaminants pass through the inner annular chamber in heat transfer relation with the high temperature section of the first tubular member, thereby providing complete combustion of the contaminants, while the particulate material travels to the downstream end of the drum through the outer annular chamber where it is subjected to a lower temperature which will not adversely effect the particulate material. | ||||||
