Description
Technical field
The utility model relates to a kind of being used to rock phosphate in powder is sieved the phosphorus ore multistage screening plant that rock phosphate in powder is divided into the ore of different grades.
Background technology
At present, the mining of the phosphorus ore enterprise down-hole of the domestic overwhelming majority all is to adopt richness to abandon poorly, to not adopting that the ore that does not reach economic taste is abandoned, so just inevitably causes ore dilution serious.In order effectively to have utilized national scarce resource, need exploit lean ore body holostrome, exploit the ore that comes out like this and be difficult to reach the chemical industry requirement, and for the lifting ore grade, inevitably need carry out sorting to the ore that extraction comes, sorting work of the prior art is generally all comparatively simple, can not split the next rock phosphate in powder of extraction to the actual conditions of the requirement of rock phosphate in powder grade and ore itself according to phosphorous chemical industry and sieve.
The utility model content
The purpose of this utility model provides a kind of phosphorus ore multistage screening plant, can not split the problem that the next rock phosphate in powder of extraction sieves to the actual conditions of the requirement of rock phosphate in powder grade and ore itself according to phosphorous chemical industry to solve in the prior art.
In order to realize above purpose, the utility model adopts following technical scheme: a kind of phosphorus ore multistage screening plant, comprise that import is used for the feed hopper that joins with the outlet of rock phosphate in powder conveying mechanism, the exit of feed hopper is provided with first horizontal screen, the sieve upper outlet of first horizontal screen links to each other with first belt conveyor by the water conservancy diversion track, the exit is provided with first slide valve under the sieve of first horizontal screen, the sieve upper outlet of first horizontal screen is connected with second horizontal screen in the below of first slide valve, the sieve upper outlet of second horizontal screen links to each other with second belt conveyor by the water conservancy diversion track, the exit is provided with second slide valve under the sieve of second horizontal screen, export in the below of second slide valve under the sieve of second horizontal screen and be connected with rotary screen, the coarse fodder outlet of rotary screen links to each other with second belt conveyor by the water conservancy diversion guide rail, and the fines outlet of rotary screen links to each other with the 3rd belt conveyor by the water conservancy diversion guide rail.
Described first horizontal screen is welded by the first track steel gap, and the upper end spacing between the two first adjacent track steel is greater than the lower end spacing.
Upper end spacing between first liang of adjacent track steel is 100mm.
Described second horizontal screen is welded by the second track steel gap, and the upper end spacing between the two second adjacent track steel is greater than the lower end spacing.
Upper end spacing between the two second adjacent track steel is 50mm.
The screen mesh size of described rotary screen is 10mm.
The compass screen surface of described first horizontal screen and the angle between the horizontal plane are 42 ~ 45 °.
The compass screen surface of described second horizontal screen and the angle between the horizontal plane are 45 ~ 51 °.
Three grades of screenings of employing of the present utility model can be split the next ore of extraction and be carried out sufficient sorting, farthest improve the grade of ore.In addition, the utility model is provided with first slide valve and second slide valve, can select the progression of sorting and the place to go that sorts out material according to the actual conditions of exploiting the ore that comes out, and can obtain meeting the ore that grade requires.
First and second horizontal screens of the present utility model are welded by track steel gap, and the upper end spacing between the two first adjacent track steel is greater than the lower end spacing, and the upper end spacing between the two second adjacent track steel is greater than the lower end spacing.Ore is easily piled up when coming down in torrents, and the upper gap of first and second horizontal screens is wider than underclearance, can avoid causing screen rate to descend because the ore accumulation causes the smitham passage, can be so that screen rate improves 10%-15%.In addition, the underclearance of first and second horizontal screens is slightly narrow, can prevent effectively that the granule barren rock that mixes in the oversize from entering sieve down by compass screen surface, avoids sneaking into of barren rock to cause ore dilution, falls end grade.
