Ore mining and crushing integrated efficient-mining device and method

Abstract

The invention discloses an ore mining and crushing integrated efficient-mining device and method. The ore mining and crushing integrated efficient-mining device comprises a mining device, wherein themining device comprises a chassis and walking mechanisms; the walking mechanisms are correspondingly arranged on the front and rear sides of the chassis; a rock collecting mechanism, an ore layer crushing mechanism, a first jaw crusher and a second jaw crusher are sequentially arranged at the top of the chassis from left to right; the ore layer crushing mechanism is used for crushing a dense ore layer into loose rocks; a pressing mechanism used for pressing ore is arranged above the crushing zone of the first jaw crusher; a hydraulic cylinder and a first screw conveyor are arranged below the chassis; the outlet end of the first screw conveyor extends into the feeding port of the first jaw crusher; the inlet end of the second screw conveyor communicates with the discharging port of the first jaw crusher; and the outlet end of the second screw conveyor extends into the feeding port of the second jaw crusher. The ore mining and crushing integrated efficient-mining device and method have the beneficial effects that the ore mining efficiency is improved; the rock crushing efficiency is improved; the crushed ore particle size uniformity is improved; and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of ore mining and crushing, in particular to a high-efficiency mining equipment and method integrating ore mining and crushing. Background technique [0002] Ore refers to stones that contain certain valuable minerals mined from mines. Stones can be used in metal mines, metallurgical industry, chemical industry, construction industry, iron (public) ) Road construction units, cement industry and sand and gravel industry and other engineering fields. The ore is divided into buried layer ore and bare layer ore. The buried layer ore is buried in the mountain body, while the bare layer ore is exposed on the ground surface. Since the bare layer ore is exposed outside, it is more convenient to mine. The existing working steps of mining the bare layer ore are as follows: firstly, the surface of the bare layer ore is broken by the vibratory crushing device of the mining equipment, so that the stones in the bare laye...

Problems solved by technology

[0003] However, although the present mining and crushing methods can process small-sized ores, there are still the following defects: 1, the stones in the bare ore layer are agglomerated into cakes, and there is only one crushing device in the mining equipment, which causes the workman to need multiple times Operate the crushing device so that the impact drill pipe on it impacts the cake-shaped stones several times, and only after the impact can the loose stones be obtained, which can facilitate the smooth crushing of the subsequent jaw crusher, which undoubtedly reduces the ore mining. efficiency

2. The evacuated stones need to be transported to the designated crushing area by transport vehicle, and the transportation distance in the middle is long, which will undoubtedly delay the crushing time and also reduce the mining efficiency of ore

3. After the workers shovel the stones into the jaw crusher, a large number of stones are piled up between the two crushing rollers, and the flow speed of the stones is slow, resulting in a long waiting time before the piled stones are broken. , which undoubtedly reduces the crushing efficiency of stones

4. The hardness of the stone is relatively high, and the loss of the two crushing rollers in the jaw crusher is large, thereby reducing the service life of the crushing roller, and most of the surface of some stones is arc-shaped, which makes it difficult for the stone to into the crushing area between the two crushing rollers, further reducing the crushing efficiency of the stones

5. The jaw crusher can only crush the stone once, resulting in the crushed small-sized ore still contains large-sized ore, so there is a defect of uneven crushing
