本文介绍了一种新型多功能跳汰机,可供试验用,电可作为小型生产用的选矿设备。一机多能,具有各种跳汰曲线的凸轮,跳汰室可以为梯形或矩形,精矿排出可筛上及筛下,适宜作对比用,对比其中的某一种结构参数,其他结构参数保持不变,比用两种不同规格及结构的跳汰机进行对比的结果更为可靠。多功能跳汰机采用凸轮箱传动,可根据选矿工艺及理论得出的跳汰曲线设计凸轮,从而得到所需要的任何形式的跳汰曲线。凸轮机构为偏心式,转动不同相位角后,跳汰机的位移值(冲程)及位移曲线形状均可改变。文中介绍了位移曲线变化情况以及速度、加速度图形。
This article describes a new multi-purpose jig that is ready for testing and can be used as a beneficiation plant for small-scale production. A machine can be more, with a variety of jogging curve of the cams, jigging room can be trapezoidal or rectangular, concentrate discharge can be sieved and sieve, suitable for comparison, comparing one of the structural parameters, the other structural parameters Remain unchanged, more reliable than using two jig machines of different specifications and configurations. The multi-purpose jig is driven by the cam box, and the cams can be designed according to the beneficiation technology and the theoretical jig curves so as to obtain any required jig curves. Cam mechanism is eccentric, the rotation of different phase angle, the jig displacement (stroke) and the shape of the displacement curve can be changed. The paper introduces the change of displacement curve as well as the velocity and acceleration graph.
