Hydrojig for jigging separation of mineral raw materials

摘要

Hydrojig for jigging separation of mineral raw materials and similar jig feed, having a multi-chamber jig box, a jig-feed carrier, and air-inlet and -outlet tank, an air control device and at least one discharge device for jig-separated material. The discharge device is integrated into the jig-feed carrier. It has a discharge chute and, in the discharge chute, below the level of the jig-feed carrier, a control flap which can be swivelled about a horizontal axis and has the width of the discharge chute, by means of which control flap the cross-section of the discharge chute can be partially blocked. The discharge control flap is connected to an oil-hydraulic control device which has a weight-loaded float which is submerged in the jig-feed, and acts on the discharge control flap with an operating cylinder-piston arrangement. The discharge control flap is arranged in the discharge chute on the side facing away from the transport direction of the jig-feed on the jig-feed carrier and interacts with a counter-flap which is arranged on the opposite side of the discharge chute in the level region of the jig-feed carrier and can likewise be swivelled about a horizontal axis. Both the discharge control flap and the counter-flap are connected by means of in each case one actuating rod to a control lever which is on the one hand pivotable about a horizontal axis and on the other hand, connected to the operating cylinder-piston arrangement. <IMAGE>
