  • MOUNT MEMBER, STRUCTURAL OBJECT MOUNT, METHOD FOR INSTALLING THE MOUNT, AND SOLAR PHOTOVOLTAIC SYSTEM USING THE MOUNT
    Publication number: 20130125959
    Abstract: A mount member (6) includes a beam (14), two arms (12, 13) for connecting the beam (14) to a strut for supporting the beam (14) and a pair of arm coupling members (26). The pair of arm coupling members (26) couples respective outer ends of the two arms (12, 13) with the beam (14). Each of the arm coupling members (26) is movable between a first state in which the beam (14) and the two arms (12, 13) are overlapped and aligned in a longitudinal direction thereof with the two arms (12, 13) being in line with each other, and a second state in which mutually facing ends of the two arms (12, 13) are spaced apart from the beam (14) relative to the first state.

  • Method of operating non-ferrous smelting plant
    Patent number: 7776133
    Abstract: In the operation, a flux mainly composed of silica ore and a non-ferrous metal-ore raw-material are charged into a smelting furnace via a conveying system. In order to increase the production amount of the metal, the flux is conveyed and treated through a first system, in which the flux is crushed in a ball mill and dried in the bail mill, and the crushed and dried flux is conveyed directly before the smelting furnace. The non-ferrous metal ore is treated and conveyed through a second system, in which it is dried with a drier and then conveyed directly before the smelting furnace. In the drier of copper concentrate, the flux is not dried at all.

    Abstract: In the operation, a flux mainly composed of silica ore and a non-ferrous metal-ore raw-material are charged into a smelting furnace via a conveying system. In order to increase the production amount of the metal, the flux is conveyed and treated through a first system, in which the flux is crushed in a ball mill and dried in the ball mill while hot air is blown into the ball mill, and the crushed and dried flux is conveyed directly before the smelting furnace. In the drier of copper concentrate, the flux is not dried at all.
