我厂用两台自制的 L128振动落砂机并联进行大型铸件的落砂。为了不使型砂把落砂机栅格孔堵塞,并使大部分砂团能顺利通过栅格孔经集砂斗落到回砂胶带上,栅格尺寸为80×80mm,比目前标准设备略大一些。集砂斗固定在落砂机的座框上,凭借集砂斗和回砂胶带之间的高度来控制出砂量。为了使落下来的披 I plant with two self-made L128 Vibration Falling Machine parallel large-scale casting sand. In order to prevent the sand from falling off the lattice grid of the sand making machine and enabling the majority of the gravel to pass the lattice hole to the graphene strip through the grid hole, the grid size is 80 × 80mm, which is slightly larger than that of the current standard equipment some. The set sand bucket is fixed on the seat frame of the dropout machine, and the amount of sand is controlled by the height between the set sand bucket and the return sand belt. To make the falling Phi
