Description
Technical field
The present invention relates to the dry-type magnetic extractor that the branch iron ore is used a kind of raw iron ores after fragmentation, raw iron ores transport after particularly a kind of fragmentation and the magnetic of dry-type magnetic extractor system.
Background technology
Iron ore is the raw material of ironmaking, contains a certain amount of gangue in the raw iron ores of mine extraction, and grade is lower, before with raw iron ores ironmaking, will carry out ore dressing processing to raw iron ores, is used further to ironmaking after the grade of raising iron ore.Ore dressing comprises dry separation and wet separation; Dry separation is the preliminary ore dressing processing that the raw iron ores after the fragmentation is carried out; Raw iron ores is iron ore after the dry separation of tentatively isolating some gangues after the dry separation and tentatively being upgrade, and then iron ore after the dry separation is carried out wet separation processing.The processing of wet separation at present is to use wet magnetic separation mostly; Iron ore is levigate after in wet magnetic separation, will using ball mill dry separation; Then with wet magnetic separator to levigate dry separation after iron ore carry out wet magnetic separation, obtain iron ore after the wet separation of the required higher grade of ironmaking.In the wet magnetic separation process, relate to levigate iron ore, the consumption of energy and equipment is very big during levigate iron ore; If the iron ore grade is low more after the dry separation, the mine tailing amount that produces after the wet separation is big more, and the tip that mine tailing takies is just big more; If it is the iron ore grade is low more after the dry separation, also big more to the freight volume of iron ore after the dry separation.So improve the dry separation efficient of raw iron ores, obtain the expense that iron ore both can have been saved ball milling after the higher dry separation of grade, can reduce again the freight volume of ore and the tip of mine tailing, the reduction beneficiation cost there is very big effect.Raw iron ores after the fragmentation is carried out dry separation processing will use dry-type magnetic extractor.Dry-type magnetic extractor is similar to ribbon conveyer; Support roller before dry-type magnetic extractor organic frame, the front end of frame have, the rear end of frame has the back to support roller; Be connected with conveyer belt between the back and front supporting roller; There is separated ore deposit plate the front lower place of conveyer belt, at a distance from the front portion of ore deposit plate the gangue storehouse is arranged, iron ore storehouse after there is dry separation at the rear portion of ore deposit plate.In the prior art; The magnetic system of dry-type magnetic extractor is in the preceding support roller on frame; Preceding support roller is the roller of non-magnetic conductor material, and the magnetic system on the frame, in the preceding support roller is that the magnetic along preceding semi-circumferential is in preceding support roller, and the device of the preceding semi-circumference magnetic in edge system is commonly referred to as magnetic pulley on the roller and frame for the non-magnetizer material, in the roller; The conveyer belt rear portion is a feed entrance point, and the conveyer belt front portion is a discharging opening.During use; Be laid in the raw iron ores after the fragmentation on the conveyer belt equably from feed entrance point; Raw iron ores after the fragmentation is fixed bed and on conveyer belt, travels forward, and when the raw iron ores after the fragmentation left magnetic pulley, the raw iron ores after the fragmentation on the fixed bed was in the magnetic field range of magnetic pulley; Magnetic field affacts the iron ore in the raw iron ores after the fragmentation on the fixed bed; Iron ore is inhaled attached on the conveyer belt because of the magnetic force that receives edge preceding semi-circumferential magnetic system more tightly, and gangue does not receive the effect of magnetic force, and dishing out along magnetic pulley tangential direction forward gets into the gangue storehouse; Iron ore is attached to the circular motion that continues on the conveyer belt along magnetic pulley because of receiving along the magneticaction of preceding semi-circumferential magnetic system, up to leave dish out downwards along the magnetic field of preceding semi-circumferential magnetic system get into dry separation after the iron ore storehouse.This dry-type magnetic extractor is when being fixed bed and on conveyer belt, travelling forward at the raw iron ores after the fragmentation; The iron ore on upper strata possibly dished out along tangential direction forward by the buffer action of lower floor's gangue; Get into the gangue storehouse, the gangue of lower floor possibly wrapped up in and dished out along downward direction and get into iron ore storehouse after the dry separation, the tiny iron filings particle in the raw iron ores after the fragmentation by holding under the arm of upper strata iron ore; In the motion of fixed bed; Be easy to held under the arm to wrap up in by gangue bring the gangue storehouse into, it is unclear to cause iron ore to separate with gangue, and the grade of iron ore is not very high after the dry separation.
Summary of the invention
