Description
Technical field
The preparation method and the production unit thereof of the premix raw material of a kind of permanent ferrite prefiring material of the present invention belong to production raw material production field, particularly the feedstock production process of wet production permanent ferrite prefiring material.
Background technology
When preparing the premix raw material of permanent ferrite prefiring material; Its key is to control the homogeneity of premix raw material granularity and the accuracy of batch mixing composition, if granularity heterogeneity, the batch mixing composition ratio of the premix raw material of preparation are inaccurate, pre-burning material sintering temperature is different in the time of will causing subsequent production; Therefore cause a large amount of waste products; Even the inadequate thermal sintering of pre-burning material after the adjustment sintering temperature, sintering temperature and influences the quality of its derived product the most at last also with difference when follow-up making magnetic device.The primary raw materials iron oxide red of said this premix raw material is the acid washing iron red recovered material that comes from metallurgy industry.Therefore, the core of guaranteeing to produce the grade quality of permanent ferrite prefiring material is to improve grade quality, the homogeneity of premix raw material granularity and the accuracy of batch mixing composition of its premix raw material.But existing production can not meet the demands.At present, the preparation method of the premix raw material of permanent ferrite prefiring material summarizes has following two kinds:
One, ball milling mechanism material
The industry generally adopts ball milling mechanism material method, uses the ball mill abrasive material, adopts the multimachine running for satisfying to produce, and ball mill quantity is many; Every table grinder batching needs to open and close the ball mill door, after release mesh, from the ball mill blanking, to stirring hold-up vessel; This method is batch production, expects loading and unloading and grinds length consuming time for every jar, and fully by MC; Labor strength is big, and mechanical floor space is big, the easy contaminate environment of slip.More than batch, in batches little, each batch quality, grade are disperseed, though sampling Detection often, the quality and the grade of the material that grinds are inconsistent, are difficult to meet the demands.
Two, ball mill, sand mill are united the system material
Adopt ball milling, sand milling to unite the system material, the input and output material mode that ball mill is opened and closed door changes batch mixing in advance into, gets into ball mill through pipeline again; And increase follow-up sand mill auxiliary abrasive; Improve production efficiency though this method solves than ball milling mechanism material, improved the homogeneity of batch mixing, but still be batch production; Still exist mechanical floor space big, the still easy contaminate environment of slip.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of premix raw material of permanent ferrite prefiring material; Produce preparation to realize premix raw material continuity; Improve the accuracy of premix raw material granularity homogeneity and batch mixing composition, and, the production efficiency that system is expected improved; Reduce labor strength, improve operating environment.
The present invention realizes through following technical scheme:
The preparation method of the premix raw material of permanent ferrite prefiring material of the present invention; At first; Adopt surge pump to send into tube mill pro rata premix coarse fodder and water blended coarse fodder slurry; This coarse fodder slurry through the continuous mixed grinding of steel ball, becomes the fine-grained premix raw material of even standard in tube mill, it is sent in the smart control jar of large vol again; And vertical circulation stirring of in jar, carrying through pump power, the horizontal stirring of paddle wheel and the side stirring of the vertical fin of tank skin, the premix raw material is carried out homogenizing handle; Then this premix raw material is carried out composition detection, and after doing the accurate adjustment of composition according to detected result, satisfying preparation, to become composition accurate, the premix raw material of the permanent ferrite prefiring material that granularity is consistent.
The preparing method's of the premix raw material of permanent ferrite prefiring material tube grinds material equipment according to the present invention, comprises the pit type mixer, tube mill; Stock chest; Large vol essence control jar and pump are communicated with through pipeline between this pit type mixer, tube mill, stock chest, the smart control jar of large vol, and slip is by pump delivery; Characteristics are that the smart control jar of large vol has the vertical recycle pump of slip and pipeline, paddle wheel, and tank skin is provided with vertical fin.
The preparing method's of the premix raw material of permanent ferrite prefiring material the technology according to the present invention may further comprise the steps:
1, premix coarse fodder and water blended coarse fodder slurry is levigate through mixing continuously in tube mill, becomes the fine granularity premix raw material of even standard;
2, the fine granularity premix raw material of above-mentioned even standard circulates vertically through pump power in the smart control of large vol jar that stirrings, large stretch of impeller laterally stir and the side of the vertical fin of tank skin stirs, and fine granularity premix raw material is carried out the homogenizing processing;
3, the premix raw material of handling through above-mentioned steps 2 homogenizing is carried out composition detection, and, composition is precisely adjusted according to detected result.
The inventive method already provides a kind of successive working method for this; Make the industry take off fully pendulum Traditional use ball mill intermittence extensive style working method, in the inventive method and device scheme, adopted the smart control of large vol jar to design; Its tank skin vertically is provided with fin; In jar big blade stirring wheel and pump power circulating line are set, premix raw material slip obtains the homogenizing processing that sufficient mechanical type stirs, stirs in this jar, then carry out composition detection and meticulous adjustment again; Therefore guaranteed that the granularity of the former slip product of premix and the height one of composition make peace precisely, for the grade quality of raising downstream magnet product has been established solid foundation; In addition, the present invention has significantly improved production efficiency, greatly reduces operator's labour intensity, and has reduced production cost, has improved operating environment.
