In general, the feeding concentration of coarse and fine-grained minerals is 20% – 30% and 15% – 25% respectively. When the rushing rapid occurs on the surface of the shaking table bed, the ore concentration can be appropriately increased. If there is a sand pile, the ore concentration needs to be reduced. 5.
