Description

Crushing device for ore outside surface

Technical Field

The utility model relates to an ore processing technology field, concretely relates to a breaker for ore deposit outside table.

Background

The boundary grade is a technical and economic parameter which has great influence on the overall economic benefit of the mine. China mines always adopt 'double-index' boundary grades. Namely the "geological boundary grade" and the "minimum industrial grade". The concept of in-table (blocks with a grade above the minimum industrial grade) and out-table (blocks with a grade between the geological boundary grade and the minimum industrial grade) is thus created.

In the correlation technique, breaker has adopted a plurality of crushing rollers from top to bottom to smash the ore, when first order is smashed, adopts the screen cloth of putting to one side to screen, and the ore that does not go into the sieve continues to pass through the second grade and smashes, then merges with the part that the first order was smashed and had gone into the sieve, accomplishes the multi-stage reduction of ore. However, this technique has the following drawbacks: (1) The inlet of the ore directly faces the extrusion part of the crushing roller, and broken stones are easy to splash to cause accidents; (2) The sieving is carried out by adopting a standing sieve below the first-stage crushing, the ore is easy to block at the position, and the ore which is not sieved is easy to block in the process of sliding down from the sieve to the second-stage crushing.

Detailed Description

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

Examples

As shown in fig. 1, a crushing apparatus for a topsides includes a casing 10, a first roller mill assembly 20, a vibrating screen 30, and a second roller mill assembly 40. The housing 10 comprises an inner chamber 11, an ore inlet bin 12 at the top, and an ore outlet 13 at the bottom. The bottom of the inner cavity 11 is obliquely arranged and is gathered at the ore outlet 13. For example, the bottom of the inner cavity 11 may be tapered (pyramid or cone) and the ore outlet 13 may be located at the bottom center of the housing 10, so that the crushed ore is not piled up and output smoothly. The ore entry bin 12 comprises a first end 121 and a second end 122 facing away from each other, the first end 121 facing upwards and towards the environment, the second end 122 facing downwards and towards the crushing area of the first roller mill assembly 20, the first end 121 and the second end 122 communicating without a straight passage between them. Here, not having a straight passage means that the crushed stone cannot splash in a straight path from the second end 122 to the first end 121. The first roller mill assembly 20 is mounted in the internal chamber 11. The vibrating screen 30 is installed in the inner cavity 11 and is obliquely arranged, the vibrating screen 30 comprises a screening part 31 and a solid part 32 which are connected, the overall height of the screening part 31 is higher than that of the solid part 32, and the screening part 31 is arranged below the discharging area of the first roller mill assembly 20. The second roller mill assembly 40 is mounted in the internal cavity 11 with its extrusion area below the discharge level of the solid portion 32. Here, the first roller mill assembly 20 or the second roller mill assembly 40 is a conventional prior art, and two rotating roller shafts are adopted to squeeze ore between the two roller shafts, so as to achieve the effect of crushing stone, which is not described herein again. Here, the crushing area refers to the area where the roller mill assembly crushes ore, i.e. the area entering between the two rollers from above, and the discharge area refers to the area where the crushed stone of the roller mill assembly is discharged after the crushing is completed, i.e. the area where the ore comes out from below the two rollers.

The working principle of the technical scheme is as follows:

the utility model discloses a breaker for ore outside table includes casing 10, first roll mill subassembly 20, shale shaker 30 and second roll mill subassembly 40, through set up the ore on casing 10 and get into storehouse 12, when carrying out the rubble through the extrusion region of first roll mill subassembly 20, the rubble can not directly splash away through first end 121, avoids causing the incident; in addition, through setting up shale shaker 30 for the ore that smashes through first roller mill subassembly 20 is changeed and is sieved, reduces the condition of jam, also makes the in-process that the ore that does not sieve slide to second roller mill subassembly 40 more smooth and easy because of the vibration of shale shaker 30 simultaneously.

In further embodiments, both the first end 121 and the second end 122 are oriented vertically and coaxially.

In another embodiment, the first end 121 and the second end 122 are communicated with each other through two symmetrical bending channels, and a diversion plate 123 is disposed on the ore inlet bin 12 right below the first end 121 to divert the material to the two bending channels. Through this setting, further reduce the rubble and splash the possibility to the external world, shunt the material that gets into simultaneously for the material gets into from the both sides in the extrusion region of first roller mill subassembly 20, and is more even, gets into the central authorities in extrusion region better, reduces the possibility that the ore roll-off extrudees the region.

In further embodiments, a cushion 124 is applied to the inner wall of the ore entry bin 12 above and to either side of the second end 122. Through this setting, when the rubble splashes appear in the extrusion region of first roller mill subassembly 20, blotter 124 can effectively cushion, avoids the rubble directly to beat on the bulkhead, promotes life. For example, the cushion 124 may be a rubber pad.

In other embodiments, the shaker 30 is a linear drive shaker or a cam drive shaker. Here, the cam type vibrating screen means that the vibrating screen 30 is vibrated by the eccentric motion of the cam.
