1000×1000下动型隔膜跳汰机是我局北选厂重选部分的主要设备之一,跳汰机入选粒度为-12+6毫米,由国外设计。本机最大弱点是冲程系数小和水冲程小,矿层难于松散,对于处理粗粒物料不大适宜。为此,对它进行了改进:第一步是减小筛面,将1000×1000毫米的筛面改为700×1000毫米,其目的是增加冲程系数;第二步是将原有的单一的筛下排矿,改为筛下筛上联合排矿,即在尾矿挡板上开一个 1000 × 1000 under diaphragm moving jig is one of the main equipment of the North electoral plant re-election part of the jig, jig selected particle size of -12 +6 mm, designed by foreign countries. The biggest weakness of this machine is the stroke coefficient is small and the water stroke is small, difficult to loose seam, for processing coarse material is not suitable. To this end, it has been improved: The first step is to reduce the screen surface, the 1000 × 1000 mm screen surface to 700 × 1000 mm, the purpose is to increase the stroke coefficient; the second step is to the original single Under the screen row of ore, replaced by sieve sieve joint drainage, that is, open a tailings baffle
