When the area of the jigging chamber is large and the stroke coefficient is relatively small, if the supplemental water is insufficient or uneven, it may cause minerals on the bed harden. (3) If the mineral contains a lot of heavy sand, it will be more difficult to separate, which may result in a decrease efficiency of the jig machine.
