人们一直致力于从理论上说明跳汰分选原理,提出了许多模型,例如,等降速理论,最小位能理论等等。这些模型都是基于平衡态对矿物运动的分析,事实上跳汰过程是一个动力学过程,所以基于上述原理是不可能正确地反映跳汰的运动特性,因而所提出的理论也不可靠。目前在跳汰机设计中,通常是靠经验选定冲程、冲次。在跳汰试验时,也是靠经验选定调试范围,通过化验跳汰产品确定最佳工作条件,这对新
People have been committed to theoretically explain the principle of jig sorting, put forward many models, for example, such as speed reduction theory, the theory of minimum energy and so on. These models are all based on the equilibrium analysis of the mineral movement. In fact, the jig process is a dynamic process. Therefore, based on the above principle, it is impossible to correctly reflect the kinematic characteristics of the jig. Therefore, the theory put forward is not reliable. Jig currently in the design, usually based on experience selected stroke, stroke. In the jig test, but also selected by the experience of debugging the scope of the test jig products to determine the best working conditions, which new
