Abstract
A kind of stainless steel slag iron selection technique.Stainless steel slag is through after sieving fragmentation, and jigging machine is supplied with on quantitative and even ground, realizes that by jigging machine slag iron separates, abrasive grit inflow concentrate pond, and tailings dewaters by spiral classifier, and water is recycling through the clarification back.This technology can guarantee that the granulated iron rate of recovery is more than 98% in the slag, and the dregginess that reclaims granulated iron is less than 5%.
Description
Affiliated technical field:
The present invention relates to environmental protection and resources conservation comprehensive utilization technique that a kind of stainless steel slag reclaims the slag iron process.
Background technology:
General containing metal 15-23% in the stainless steel slag, the characteristics of stainless steel slag are: 200 be, 400 be that stainless steel is magnetic, 300 is that stainless steel does not have magnetic.Because stainless above characteristics, general slag is handled the processing that the magnetic separation process that adopts obviously is not suitable for stainless steel slag, and the production efficiency of the ball milling-shaking table technology that adopts usually at present is lower, obviously do not satisfy extensive steel mill slag handle.
The present invention can realize the efficient separation of stainless steel slag iron.
Summary of the invention:
Low in order to overcome existing stainless steel slag treatment process treatment effeciency, low and the impure shortcoming of regenerant of the rate of recovery, the invention provides a kind of improved jigging iron separation technique, this technology can guarantee that the granulated iron rate of recovery is more than 98% in the slag, and the dregginess that reclaims granulated iron is less than 5%.
The technical solution adopted for the present invention to solve the technical problems is:
Slag is through supercooling, after the fragmentation through rod mill in small, broken bits after, jigging machine is supplied with on quantitative and even ground, realizes that by jigging machine slag iron separates, abrasive grit flows into the concentrate pond, slag is through the spiral classifier dehydration, water recycles after through clarification.
The epigranular of feed and delivery rate evenly are the necessary conditions of jigging machine operate as normal, the problem that the design has solved high-recovery and reclaimed metal purity.
The invention has the beneficial effects as follows:
The stainless steel slag that can realize high-recovery and recovery granulated iron purity selects iron.
Description of drawings:
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the system flow chart of stainless steel slag jigging iron separation technique.
A101 feed bin among the figure, A102 oscillating feeder, A103 belt conveyor, A103/1 belt conveyor, A103/2 are expected hole, A104 jaw crusher, the A105 belt conveyor, A106 jaw crusher, A107 belt conveyor, the A108 feed bin, A108/1 oscillating feeder, A109 belt conveyor, the A110 oscillating feeder, A111 rod mill, A112 vibratory sieve, the A113 belt conveyor, A113/1 expects hole, A114 spiral classifier, A115 feed bin, the A116 oscillating feeder, A117 2 tunnel sub-material chutes, A118/1,2 other dynamic formula jigging machines, A119 spiral classifier, A119/1 are expected the hole.
The specific embodiment:
In Fig. 1, loading machine is the A101 feed bin of packing into through the slag that tentatively smashes, and bar screen is established at A101 feed bin top, and lumpiness is slid down greater than the slag of 300mm and needed with reinstalling feed bin after the drop crushing, and bulk metal is also here directly selected, and does not enter follow-up flow process;
Lumpiness enters feed bin less than the slag of 300mm, carry the A103 belt conveyor equably by the A102 oscillating feeder, set up on this belt feeder and manually select the iron platform, lumpiness metal bigger or slag iron separation is manually selected thus, be delivered to A103/2 material hole through the A103/1 belt conveyor, no longer enter subsequent handling.Slag is delivered to the A104 jaw crusher through the A103 belt conveyor and carries out primary fragmentation to 80mm, be delivered to the A106 jaw crusher by the A105 belt conveyor then and carry out second-time breakage to 30mm, be delivered to the A108 feed bin through the A107 belt conveyor then and carry out intermediate storage, then by the A108/1 oscillating feeder, the A109 belt conveyor, the A110 oscillating feeder is given the A111 rod mill equably, slag particle degree after the process rod milling is less than 0.7mm, behind the A112 vibratory sieve, the piece iron of selecting is transported to A113/1 material hole through the A113 belt conveyor, other granularity is transported to the A115 feed bin less than the slag of 0.7mm by the A114 spiral classifier, give A118/1 through the A116 oscillating feeder equably through A117 2 tunnel sub-material chutes again, 2 other dynamic formula jigging machine feeds, the concentrate that jigging is selected enters A118/3 concentrate pond, and the tailings behind the jigging enters A119/1 material hole after by A119 spiral classifier drainage.
Water is through clarification back reusable edible in the system.
