Specific embodiment
Invention is further described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, a kind of electrolytic manganese residues resource utilization dedicated system, including sequentially connected manganese slag pretreatment dress
Set, the broken molding machine of manganese ground-slag and burning processing system, the manganese slag pretreatment unit includes sequentially connected spiral washery slag
Machine 1, roller classifying screen 2 and manganese slag filter press 3, the discharge port of the spiral washery slag machine 1 and the feed inlet of the roller classifying screen 2

Working principle of the present invention is as follows:
Firstly, carrying out the cleaning of manganese slag by spiral washery slag machine, sieving and grading then is carried out to manganese slag using roller classifying screen, then will
Manganese slag after classification carries out filters pressing operation, that is, completes the pretreatment of manganese slag, will complete pretreated manganese slag and lime or basic species
Material carries out ingredient, passes through the first conveyer after the completion of ingredient and is delivered to dusting machine, carries out crushing operation, then by smashed manganese slag
Mix is carried out with lime, the material after mix is delivered to nodulizer by second conveyor and is formed, that is, realizes to manganese slag
Recycling molding prepares lightweight aggregate, material importing rotary kiln is then carried out burning processing by third conveyer, realization prepares swollen
Change lightweight aggregate, finished product is finally subjected to depositing dust desulfurization process and tail while burning processing by the discharge port output of rotary kiln
The effect that the nitrogen oxides in exhaust gas is carried out to degradation treatment is realized in gas disposal.
Using the above structure due to the present invention, the waste residues such as manganese slag by the prerinse of manganese slag pretreatment unit, classification and
Filters pressing forms the net slag of unified specification, then crushes by ingredient and is shaped to lightweight aggregate and carry out burning processing, while to production
Such as nitrogen oxides of exhaust gas in the process is handled, and the whole production line system being recycled to manganese slag is realized, and is improved
Manganese slag waste water treatment efficiency, operating cost is low, realizes sustainable development.
