苏联地质技术联合公司专业设计局研制的OMCK-2型跳汰机,用于重力分选粒度小于12毫米的岩矿石粒状试样和砂矿试样。跳汰机的工作原理是使矿粒混合物在素流水流中按比重分选。物料的分选是在水流方向变化的相互作用下发生的。重颗粒富集在跳太室的下层,轻颗粒在上层。跳汰机内安装了冲次和冲程调节装置,实现了不停机的平稳 The OMCK-2 Jig, developed by the Professional Design Bureau of the Soviet Union Geotechnical Engineering Company, is used for the grained samples of rock ores and sand samples for gravity separation of particle sizes less than 12 mm. The working principle of the jig is to make the mineral mixture by gravity sorting in the stream of prime water. The sorting of materials takes place under the influence of the changing direction of the water flow. Heavy particles enrichment in the lower jump too room, light particles in the upper. Jig installed stroke and stroke adjustment device, to achieve a smooth non-stop
