PURPOSE:To perform cast-in and exhaust of masses in a short time by supporting a tallet with four barrel pots so as to be capable of tilting round a horizontal shaft, driving two sets of link mechanisms simultaneously by an elevating/sinking plate on the center shaft of said tallet, and providing possibility of simultaneous opening and closing of lids of the pots. CONSTITUTION:A tallet 4 is held vertical and an elevating/sinking mechanism 31 built in its center shaft 8 is operated to lift an elevating/sinking plate 33, and a long link 22 and a short link 24 of two sets of link mechanisms 29 are rotated outwards. This opens a coupling plate 19 as in an arc to both sides as shown by an imaginatory line, and four caps 17 and four lids 18 mounted on said plate are opened simultaneously. This enables easy cast-in of masses. When grinding is finished, the tallet 4 is rotated round a horizontal shaft 2 so that it faces down, and the elevating/sinking mechanism 31 is actuated to open at the same time as the four lids 18, and now the masses in the barrel pots are exhausted to a stocker situated below. |
