SU1259011A1 - Arrangement for delivering ore and secondary crushing of oversize lumps - Google Patents

Description

one

The invention relates to the mining industry and can be used in the underground mining of mineral deposits.

The purpose of the invention is to reduce the cost of producing ore with pieces of standard sizes by reducing the volume of mine workings.

The drawing shows the proposed device.

The device includes delivery production 1 with ore 2 placed in it, feeder 3, screen 4, transport vessel 5, haulage production 6 with transported oversized ore pieces 7, delivery vehicles of oversize - roller table 8, hoist 9 with pusher on a monorail 10, screen 115 point of crushing non-dimensions 12 with an additional screen 13 and a bottom floor 14.

The device works as follows.

Although 4 into transport vessel 5, the nahrd is located on the haulage mine 6. When a large piece 7 is placed on the screen 4, it is separated from screen 4 by 5 by the live rolls 8 and is moved along it. along the haulage opening 6 above the transport vessel. To separate and move the oversize 7 over the roller table 8, a hoist 9 is installed with a roller on the monorail 10. The pusher is adapted to longitudinal movement over the roller table. Under the conveyor 8 is installed screen 1 to eliminate spillage.

The oversized pieces 7 are moved away from the loading point of the conditional ore to the crushing point 12 in the haulage and crushed at a rumble 13 by a bottom bed 14, installed above the transport vessel 5 and conjugated on the same level as the roll table. At this, the crushed material falls into the transport vessel 5, into which it is possible to load the conditioned ore 2.
