Description
Technical Field
The utility model relates to a manganese zinc ferrite preparation field, concretely relates to ball mill that is used for high magnetic conductivity manganese zinc ferrite to prepare.
Background
The Mn-Zn ferrite is one of soft magnetic ferrites, belongs to a spinel structure, and is mostly prepared from oxides of Fe, Mn and Zn and salts thereof by adopting a ceramic process. It has a good initial permeability and is generally used in the frequency range of 1 kHz to 10 MHz. The Mn-Zn ferrite material with high magnetic conductivity is widely applied to anti-electromagnetic interference noise filters, broadband transformers, transmission systems of various communication transmission devices, lighting transformers and electronic ballasts in daily life. The research on the magnetic conductivity of manganese-zinc ferrite materials at home and abroad is very important, at present, raw materials are important factors influencing the performance of the ferrite and are directly related to various performances of the ferrite, wherein the purity, impurities and reaction activity of the raw materials have great influence on the performance of the ferrite materials. Under the same process conditions, an increase in the purity of the raw material, the reactivity, means an increase in the magnetic permeability. Specifically, the raw materials such as Fe2O2, MnO, ZnO and the like have large powder fineness or surface area and good reaction activity, and the manganese-zinc ferrite with good magnetic conductivity can be easily obtained under certain process conditions. However, fine raw material powders or raw material powders having different fineness are more likely to agglomerate, and are more difficult in terms of mixing uniformity and powder handling. Therefore, it is important for the pretreatment of the raw material. The prior pretreatment (fine grinding) for raw materials is mostly ball-milled by a ball mill, namely, the raw materials are crushed by rotating steel balls. However, the conventional ball mill cannot ensure the fineness of all the pulverized raw materials due to the structural problem, and the subsequent particles may be excessively pulverized due to the delivery speed even during the delivery process, so that the cost is higher by using other high-precision pulverizing equipment.
