Description

one

The invention relates to the field case and can be used in the open development of useful mineral deposits.

The purpose of the invention is to increase the productivity of the conveyor lift and reduce the operating costs of servicing the crushing and transshipment point.

The drawing shows the crushing and transshipment point, a section along the axis of the inclined shaft elevator conveyor.

The device consists of a main 1 and an additional 2 bunkers, a crushing crane, a bilke 3, an inclined 4 and a horizontal-5 openings with conveyors of loading feeders 6, a well 7, an inclined shaft with a conveyor elevator 8.

The device works as follows.

Bunker 1 receives rock and unloads it directly or the feeder into the crusher. Crusher 3 crushes the rock and feeds it to the feeder 6, which transmits the crushed rock to end

-

Rolling elevator 8. In the case of stopping the conveyor elevator of the inclined shaft, the crushing device continues to work. The main bunker receives the rock and discharges it into the crusher. The crusher crushes the rock and feeds it to the feeder 6, which transfers this rock to the inclined production conveyor 4, loading the rock into an additional bunker 2. The flow of the crushed rock from the crusher to the one or the other feeder is produced by a flap. When the crusher stops, the reloading device can continue to work. In this case, the additional bunker ships the rock in it to the feeder, which transfers it to the horizontal production conveyor 5. In addition, the additional bunker can ship the rock to the conveyor lift parallel to the rock shipment by the crusher.
