Abstract
The present invention relates to a kind of manufacture method of manganese-zinc ferrite magnetic, belong to the manufacturing process area of manganese-zinc ferrite magnetic, raw material is carried out raw material ball milling after dispensing, dispensing, raw material after ball milling is subjected to press filtration, dried again after press filtration is complete, carry out carrying out second of ball milling after the completion of pre-burning, pre-burning after drying, husky mill is carried out after second of ball milling is complete again, sprayed after the completion of sand mill, it is ensured that on the premise of uniformity and stability, reduce production cost.
Description
Technical field
The present invention relates to a kind of manufacture method of manganese-zinc ferrite magnetic, belong to the manufacturing process neck of manganese-zinc ferrite magnetic
Domain.
Background technology
The production of manganese-zinc ferrite magnetic is nothing more than two kinds of techniques, and one is dry process, and two be wet processing.Most enterprises
Always using traditional wet method spray art twice, the uniformity and stability of the technique have incomparable excellent of other techniques
Point, but its production cost is high, 15-20% about higher than dry process；And the production cost of dry process is low, but the powder one of production
Cause property and stability, in the case where technology controlling and process level is consistent, magnetic particle capability does not reach the level of wet processing, and wet method is twice
Spray art flour mill flow is dispensing, ball milling, once sand milling, spraying, pre-burning, secondary ball milling, sand milling, secondary spraying.Once spray
Mist is commonly called as red spray, and it is pure water drying will to be added in the red slurry of wet mixing that it, which is acted on, obtains powder, intermediate demand addition adhesive
PVA.It is result in into the raising of production cost.
The content of the invention
Present invention aims at provide a kind of manufacture method of manganese-zinc ferrite magnetic, it is ensured that before uniformity and stability
Put, reduce production cost.
The manufacture method of manganese-zinc ferrite magnetic of the present invention, raw material is carried out by raw material ball milling after dispensing, dispensing,
Raw material after ball milling is subjected to press filtration, is dried again after press filtration is complete, carries out carrying out second after the completion of pre-burning, pre-burning after drying
Secondary ball milling, is sanded again after second of ball milling is complete, is sprayed after the completion of sand milling.
Raw material slurry after the manufacture method of described manganese-zinc ferrite magnetic, ball milling is pumped into filter press using slurry
It is interior, the moisture in slurry is dropped off by filter press press filtration.
Conveyer, filter press press filtration are set below the manufacture method of described manganese-zinc ferrite magnetic, filter press discharging opening
Later, raw material is dropped on conveyer into pie, is transported in rotary kiln and is dried by conveyer.
The present invention is had an advantageous effect in that compared with prior art：
The manufacture method of described manganese-zinc ferrite magnetic, in terms of technological process, press filtration spray art removes three process
Outside press filtration and the drying of the 4th procedure and twice spray art are different, both other processes are consistent, but only once sprayed
Mist is operated, and is entirely different compared with spray art twice from integrated artistic principle, and need not be in spraying
When use binder PVA, reduce production cost, be in order that magnetic is viscous and granulating, so as in spray drying due to adding PVA
When, reduce environmental pollution and waste of material that resulting dust is caused.Therefore press filtration drying is employed, it is just dry without spraying
It is dry.
Embodiment
Embodiments of the invention are described further below：
The manufacture method of manganese-zinc ferrite magnetic, by iron oxide 50-55mol%, manganese oxide 33-38mol%, zinc oxide 7-
12mol% is carried out raw material ball milling after dispensing, dispensing as raw material, and the raw material after ball milling is carried out into press filtration, entered again after press filtration is complete
Row drying, carries out carrying out second of ball milling after the completion of pre-burning, pre-burning after drying, carries out husky mill after second of ball milling is complete again, husky
Sprayed after the completion of mill.
Raw material slurry after the manufacture method of described manganese-zinc ferrite magnetic, ball milling uses 150ZIBL-35 type Pulp pumps
It is pumped into XYAGF6/1000-UK type filter presses, opens filter press and fall most of moisture content pressure.
The manufacture method of described manganese-zinc ferrite magnetic, filter press compaction pressure is 20MPa, and filter pressure is 6Kg/
cm2, raw material is pressed into pie, and revolution kiln drying is transported to through filter press lower belt, and drying temperature is 450 DEG C, and one ton of material dries
The dry time is 40min.
3 successive batches of manufacture method of manganese-zinc ferrite magnetic described herein are taken, numbering is respectively：A1, A2,
A3.The secondary spray art of traditional wet method：Normal production batch is taken at random, and lot number is：B679-1, B679-2.
Wherein by semi-quantitative analysis data display, technical scheme is miscellaneous in finished product compared to secondary spray art
Matter Cl-Content is reduced to 600-700PPM by about 1200PPM.
