Description
Technical field
The invention belongs to iron ore fine grinding technical field, particularly a kind of iron ore by dry method fine grinding system.
Background technology
The fine grinding of iron ore is indispensable step in Mining Market, and existing iron ore fine grinding method is divided into wet method and does
Method, wet method iron ore fine grinding need to consume a large amount of water, very not environmentally；Existing dry method iron ore fine grinding method is will be after crushing
Iron ore passes through roll-in, is screened after roll-in by V-type powder concentrator, and the coarse granule after screening is sent into ball mill and is ground,
Fine powder is screened again by powder concentrator, and the coarse granule after ball mill grinding is generally no longer screened, obtained iron ore powder
Grain size difference is larger, disunity, and needs to use at least two powder concentrators during fine grinding, and energy consumption is larger.
Invention content
Goal of the invention：The deficiency that the purpose of the present invention is be directed in current technology provides a kind of iron ore by dry method fine grinding system,
Technique is compacter, carries out material particular diameter classification using a powder concentrator, adjusting process flow makes all materials by selecting powder
Machine filters out finished product after being classified, improve final product quality；
Technical solution：A kind of iron ore by dry method fine grinding system, the equipment used include including raw material storage, raw material conveyer belt, raw material
Whirlwind recovery cylinder after elevator, current stabilization storehouse, roll squeezer, ball mill, mill, elevator, powder concentrator, cycle after exhaust blower, mill after mill

Machine outlet connection ball mill inlet, elevator after ball mill outlet connection is ground, ball crusher air outlet connect whirlwind recovery cylinder after mill,
Whirlwind recovery cylinder is connected with exhaust blower after mill after mill, and whirlwind recovery cylinder exports elevator after connection mill after mill, and elevator goes out after mill
Mouth connection powder concentrator entrance, powder concentrator coarse powder outlet connection ball mill inlet, the outlet of powder concentrator fine powder connects warehouse for finished product, powder concentrator
Air outlet connects whirlwind recovery cylinder, whirlwind recovery cylinder outlet connection warehouse for finished product by circulating fan, and whirlwind recovery cylinder is connected with row
Wind turbine；
Advantageous effect：The present invention provides a kind of iron ore by dry method fine grinding system, and the material of roll-in is sent directly into ball mill carries out
Grinding, whirlwind recovery cylinder and exhaust blower after mill, are taken out of thinner iron ores particle by big wind-force after connection is ground after ball mill,
Using whirlwind recycling machine recycling after mill powder concentrator is sent into be screened, thicker iron ores particle and agglomerate then stay in the ball mill into
Row grinding, the material after grinding are sent into centrifugation powder concentrator and are screened, and thin powder recovery to warehouse for finished product, coarse powder then sends ball back to after screening
Grinding machine is regrind；The iron ore by dry method fine grinding system need to only use a powder concentrator to carry out material particular diameter classification, reduce
Number of devices, substantially reduces equipment cost, and all finished products are to obtain powder after being screened by cyclone cluster, final product quality is big
It is big to improve；Finished product recycling is carried out using whirlwind recovery cylinder in the iron ore by dry method fine grinding system, greatly reduces windage in system,
Wind turbine energy consumption is reduced, while whirlwind recovery cylinder maintenance cost is well below bagroom.
