Lithium battery ceramic separator powder preparation method and apparatus thereof

A dispersion-blending based particle size-improved lithium battery ceramic separator powder preparation method, comprising:

• transporting a first raw material to a sand mill assembly to obtain a first powder;
• and
• performing a complex grinding inspection operation on the first powder;
• wherein the complex grinding inspection operation comprises:
• 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;
• dispersing and mixing a second raw material and the second powder according to a dynamic mixing ratio to obtain a mixed material;
• and
• transporting the mixed material to the sand mill assembly to perform grinding on the mixed material;
• wherein the dynamic blending ratio is obtained by the following steps:
• acquiring a feeding rate of the second raw material;
• acquiring a discharge rate of the second powder;
• performing speed ratio processing on the feeding rate and the discharge rate to obtain a mixing flow rate ratio;
• inspecting whether the mixing flow rate ratio is less than or equal to a preset mixing flow rate ratio;
• and
• increasing the feeding rate of the second raw material and decreasing the discharge rate of the second powder when the mixing flow rate ratio is less than or equal to the preset mixing flow rate ratio.
