Description

It is a kind of energy conservation Rare Earth Mine drying, roasting integral type rotary system
Technical field
The present invention relates to rare-earth smeltings to separate production system technical field, relates particularly to a kind of energy saving Rare Earth Mine baking Dry, roasting integral type rotary system.
Background technique
Rare earth refer to lanthanum (La) in the periodic table of chemical element, cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), Europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu), scandium (Sc) and yttrium (Y) 17 kinds of elements.The rare earth mineral deposit generally useful constituent all containing there are many, wherein rare earth, niobium, iron etc. are main synthetical recovery object. Many large-scale niobium deposits, iron ore-deposit, phosphorus deposit and nepheline mineral deposit are also rare earth mineral deposit simultaneously in the world.
Ore dressing processing must generally be carried out to rare-earth original ore to be used further to smelt separation, since rare earth rawore is mostly rare earth fluorine carbonic acid Salt can not carry out the rare earth element for directly leaching the inside, in addition, rare-earth original ore humidity is big, containing 10~15% moisture, usually Rare-earth smelting separation before need to rawore carry out calcination process, be translated by pyrolytic as rare earth oxide, fluorine oxygen Change rare earth, rare earth fluoride rare earth compound is leached again, while releasing carbon dioxide and vapor.
Currently, the roasting of rare earths material is usually first rotary kiln, dries, roasts again again later, existing more in rare-earth trade Platform multilevel rotary kiln roasting technique continuous use aspect is more in the presence of incoherent situation is connected, and exists in artificial in most cases The case where turning, since rare-earth original ore humidity is larger, majority is fed by the way of artificial spade material when charging, through too low After temperature drying, then by manually pack collect after by manually putting into an other rotary kiln carry out high-temperature roasting, descendant is completed in roasting Work carries out weighing pack.First by the way of the charging of artificial spade material and intermediate, end rewinding pack, worker's workload It is larger, while during manual operation, if worker's safety device wearing is irregular, it is easy to cause silicosis et al. to operator Body health problem;Secondly as material residence time in rotary kiln is short, causes to consume energy when roasting high, furthermore also result in roasting Uneven, the unstable quality of ore bed time afterwards;Again, since Rare-Earth Magnetic is floated, mine ore particle granularity is big, and after roasting, artificial turn is expected With fugitive dust is easy to produce during pack, cause mineral aggregate loss big.
Summary of the invention
For above-mentioned worker's larger workload, there are operational risks, and the defect being hazardous to the human body, mesh of the invention Be to provide a kind of energy saving Rare Earth Mine drying, roasting integral type rotary system, the present invention passes through integral type rotary system Setting completes drying, roasting and cooling in same rotary kiln, which greatly reduces manual operation, operation wind Danger and the injury to human body, high degree of automation consume energy low, energy saving.
