Abstract
The utility model discloses a can automatic sand return overflowball mill of material, mill discharge gate department are equipped with the pulp screen that is used for sieving the sand return material, still include one be used for carrying the sand return material take baffle shirt rim band conveyer, band conveyer is fixed in mill one side by the support, and the band conveyer afterbody is located the pulp screen below, and the head is located mill inlet pipe top, is equipped with the flash pipe that accesss to band conveyer material loading section on the pulp screen, and band conveyer head discharge hopper lower extreme has the overflow pipe that accesss to the mill inlet pipe. The utility model discloses the sand return material that can make mill production bring forms closed circuit state, and the raising the output is carried matter energy saving and consumption reduction and has been brought the convenience for equipment, can reduce intensity of labour.
Description
Technical field
The utility model relates to the ball mill that ore grinding is used, specifically overflowing of a kind of sand return material automaticallyFlow pattern ball mill.
Background technology
Overflowball mill is a kind of ore pulp product kind equipment of producing, and broken ore particle is mixed by waterBecome ore pulp, overflow to pulp tank, whole process can produce larger particles material, is below referred to as sand returnMaterial. Its sand return material amount generally can increase and significantly increase with inventory. Under normal circumstances, sand return material isBe transported to mill feeding mouth by artificial go-cart cleaning.
Taking rock phosphate in powder as example, the lower (3.1g/cm of its true specific gravity3), while normally production, require concentration to reach70% (producing most economical), according to normal volume comparison, when ball mill inventory is 70t/h, ore pulpProduction can produce the sand return amount of 5t/h. Relying in such cases artificial go-cart cleaning sand return material, averageCleaning in every 10 minutes once, has increased labour intensity and correlative charges in the middle of invisible, and for operatorMember is autonomous, and cleaning consciousness is had relatively high expectations, and if there is not clearing up in time phenomenon, can result in blockage, seriousTime burst overflow pipe accident, affect system driving rate.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of sand return material is automatically providedOverflowball mill, can improve grinding machine production efficiency, reduces staff's labour intensity.
For achieving the above object, the utility model has adopted following technical scheme: grinding machine discharging opening place establishesThere is the pulp screen for sieving sand return material; Also comprise a band dividing plate shirt rim skin for delivery of sand return materialBand conveyer, described belt conveyor is fixed on grinding machine one side by support, and belt conveyor tail is positioned atPulp screen below, head is positioned at mill feeding pipe top, and pulp screen is provided with and leads on belt conveyorThe flash pipe of material end, there is the overflow pipe that leads to mill feeding pipe belt conveyer head discharge funnel lower end.
To the steady material loading of belt conveyor, the material loading section of belt conveyor tail is horizontally disposed for convenience.
The beneficial effects of the utility model are: by the band dividing plate of carrying sand return material is set outward at grinding machineShirt rim belt conveyor, can automatically collect sand return material and carry and return to grinding machine grinding, makes grinding machine rawThe sand return material that product brings forms closed circuit state, gives equipment increasing yield and improving quality the energy-saving and cost-reducing convenience of having brought.Taking phosphorus ore as example, be that under the prerequisite of-100 order >=70%, ball mill output can be carried in slurry fineness indexHigh by 20%, can also reduce ore grinding and cross crushing phenomenon simultaneously, impel final products granularity more even, fullFoot procedure is produced. In addition, sand return material does not need manually to transport, and can reduce labour intensity.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is carried out clearly and completelyDescribe.
As shown in Figure 1, grinding machine 1 discharging opening 12 places are provided with the pulp screen 3 for sieving sand return material; WithBe fixed on grinding machine 1 one sides, skin in the band dividing plate shirt rim belt conveyor 2 of carrying sand return material by support 6Band conveyer afterbody is positioned at pulp screen 3 belows, and head is positioned at mill feeding pipe 11 tops, pulp screen 3Be provided with the flash pipe 5 that leads to belt conveyor tail material loading section 23, belt conveyer head 21 unloadsThere is the overflow pipe 4 that leads to mill feeding pipe 11 funnel 24 lower ends.
Belt conveyor is selected the shirt rim belt conveyor with dividing plate, can reduce ore pulp at lifting processIn Guo Lou Fa spill.
To belt conveyor material loading reposefully, the material loading section 23 of belt conveyor tail 22 is for convenienceHorizontally disposed.
Its operation principle is as follows: the ore pulp that screening machine 3 overflows grinding machine discharging opening 11 sieves, thinGranule materials is flow in pulp tank by the tremie pipe 31 of bottom, and coarse granule material flow to skin through flash pipe 5With the material loading section 23 of conveyer 2, then be promoted to grinding machine 1 feed end top, warp through belt conveyor 2In the feed pipe 11 of the grinding machine that discharge funnel 24 and flash pipe 4 flow to certainly, thereby return to grinding machine 1 weightNew grinding, produces thereby realize grinding machine the sand return material closed cycle bringing.
