Abstract
The invention discloses a grading method for fine machining of soda feldspar. The soda feldspar is graded by improved spiral classification equipment after being grinded into powder by a rod mill; substandard soda feldspar powder is returned to the rod mill to regrind; the standard soda feldspar powder enters a desliming bucket via a slurry pump; the deslimed product enters an internal circulation system; and a product containing an impurity finally enters the internal circulation system. By adopting the method, the soda feldspar is graded. Thus, the grading method is large in handling capacity and good in material stripping condition; the yield can be increased by about 30%; the granularity is controlled in balance; and the whiteness of grain flour is improved and is stable.
Description
Technical field:
Patent of the present invention relates to the accurately machined stage division of a kind of albite.
Background technology:
At present in the albite fine-processing technique, hierarchical processing method, generally be mineral products to be ground by the slag stock pump with rod mill pump into the hindered settling device, the rod mill that returns that requires greater than raw meal particle size grinds again, and the desliming bucket that enters that meets grinding particle size breaks away from impurity elimination; Because the hindered settling device is closed type operation, and industrial water, worker's operant level are required very high, cause this hierarchical approaches treating capacity little, granularity control is unbalanced, and material is peeled off in bad order, and the fine powder whiteness is inadequate.
Summary of the invention:
The object of the invention provides the accurately machined stage division of a kind of albite;
Patent of the present invention is to adopt following technical scheme to realize the purpose of its invention: the accurately machined stage division of a kind of albite, after it adopts the rod mill grinds by albite, (patent No. is the screw classifying equipment after improving: 201320379380.5, denomination of invention is: mica separate type screw classifying unit mahine) carry out classification, albite in powder not up to standard is returned rod mill to be refaced, albite in powder up to standard enters the desliming bucket through the slag stock pump, product introduction internal circulation system after the desliming, the impure last person.
Owing to having adopted above-mentioned technical method, the present invention has realized its goal of the invention preferably, adopts the present invention that albite is carried out classification and processes, treating capacity is large, can improve output 30% left and right sides granularity control balanced, material is peeled off all right, improves preferably refined flour whiteness and stable.
The specific embodiment:
Be described further below in conjunction with summary of the invention:
Embodiment 1:
By invention as can be known, the accurately machined stage division of a kind of albite, after it adopts the rod mill grinds by albite, (patent No. is the screw classifying equipment after improving: 201320379380.5, denomination of invention is: mica separate type screw classifying unit mahine) carry out classification, albite in powder not up to standard is returned rod mill to be refaced, albite in powder up to standard enters the desliming bucket through the slag stock pump, product introduction internal circulation system after the desliming, the impure last person.
Screw classifying equipment after the present invention improves, rod milling discharging opening place's slurry box in the former design and the displacement of supporting slag stock pump are installed, to carry out classification in the newly-increased spiral classifier precipitation zone of rod milling discharging opening ore pulp chute introducing, after material is classified, meet the grinding particle size requirement through the spiral classifier downflow weir to the mica filter screen, mica in the material is taken off, and the ore pulp that has taken off mica directly is delivered to the desliming bucket through the slag stock pump and carries out the desliming impurity elimination; Large granular materials is delivered to the rod milling of sand return chute by screw spindle after the classification of spiral classifier precipitation zone, again grind.
Claims (1)
