The invention relates to the technical field of the loose specific weight of MnZn ferrite powder, in particular to a process control method for improving the loose specific weight of the MnZn ferrite powder, the production cost is controlled by selecting iron oxide red with the loose specific weight of 0.45 g/cm < 3 > min as a raw material, the solid content of slurry formed after a presintering stage is controlled by controlling the temperature of an inlet in a spray tower, therefore, the loose charge ratio of the powder is controlled, and the loose charge ratio of the powder is increased on the premise that the using amount of a dispersing agent is not increased.
本发明涉及MnZn铁氧体粉料松装比技术领域，具体为MnZn铁氧体粉料提高粉料松装比的工艺管控方法，通过选择松装比为0.45g/cm3min的铁红为原料来控制生产成本，通过控制喷雾塔内部进口温度，来控制预烧阶段后形成的料浆的固含量，从而对粉料的松装比进行控制，实现分散剂用量不增加前提下提高粉料松装比。
