☆The jig bed is smooth in pulsation and uniform in distribu-tion due to use of beneath-the screen-plate air chamber.

☆A simple and reliable jigging operation is ensured for use of a common air valve for a multiple of compartments.

☆The length of star-wheel extractor is much reduced as a result of the arrangement of extractor at jig'slower part.This has led to effective elimination of jamming-up of re-jects and loss of clean coal.

☆Under screen water is supplied uniformly along screen plate's entire length，making it possible for the jig bed to pulsate in a steady manner.

☆Use of sophisticated PLC and touch-screen open-loop control system，and the control of parameters is much fa-cil it ated because of the possibility to modify screen data in visual manner and make interference-free A I switch-over.

☆Design of jigging process can be made for users by our professional design personnel free of charge.
