跳汰机是在非稳定水流中处理粗、中粒金属矿石的常用重选设备。它是利用偏心连杆带动橡胶隔膜(或活塞)往复运动造成的脉动水为松散手段,使矿粒群上下相对运动而分层。分层的结果是重矿粒富集在床层的下部做为精矿从下部排出,而上部轻矿粒做为尾矿经尾板(溢流堰)水平流动排出。跳汰机内上下运动脉动水的速度和加速度的变化(跳汰曲线)直接关系到跳汰机中床层的 Jig is a commonly used re-election equipment for processing coarse and medium-grain metal ores in unstable water. It is the use of eccentric rod-driven rubber diaphragm (or piston) caused by the reciprocating movement of pulsating water as a loose means, the mineral particles up and down the relative movement and stratification. As a result of the stratification, the heavy mineral particles are enriched in the lower part of the bed as a concentrate discharged from the lower part, while the upper part of the light mineral particles is discharged as tailings flowing horizontally through the tail plate (overflow weir). Jig up and down movement of pulsating water speed and acceleration changes (jig curves) directly related to the jig in the bed
