LITHIUM BATTERY CERAMIC SEPARATOR POWDER PREPARATION METHOD AND APPARATUS THEREOF

The disclosure provides a dispersion-blending based particle size-improved lithium battery ceramic separator powder preparation method and an apparatus thereof. The aforementioned dispersion-blending based particle size-improved lithium battery ceramic separator powder preparation method includes transporting a first raw material to a sand mill assembly to obtain a first powder; performing a complex grinding inspection operation on the first powder. The complex grinding inspection operation includes: inspecting the first powder to obtain a first particle size parameter; determining whether the first particle size parameter is greater than a preset particle size parameter; transporting the first powder to a powder buffer tank to form a second powder, if the first particle size parameter is greater than the preset particle size parameter, and dispersing and mixing a second raw material and the second powder according to a dynamic blending ratio to have the second powder enter the sand mill assembly together with the second raw material for grinding, so that the raw material of the previous process can be ground timely, and the material obtained through grinding the raw material can enter the equipment of the next process, thereby reducing the impact of repeated grinding of powder on the rhythm and efficiency of the production line.
