(2) In the ball milling process, firstly, the technological parameters of the slurry discharged from the slurry outlet of the ball mill are measured and controlled, and then the further detailed measurement and control are determined according to different applications of the slurry, so that when the slurry is transferred to different places, the technological parameters of the slurry can be kept stable, the accurate operation of the subsequent process is facilitated, the slurry can be timely and accurately adjusted or returned to the previous step for making up, each link is refined and strictly controlled, the condition of waste slurry is reduced, and the control is convenient;
(3) in the spray drying process, the technological parameters of the powder or the micro powder are measured and controlled at the discharge conveyer belt under the tower, if the technological parameters can not meet the preset requirements, the technological parameters of spraying can be directly measured and controlled, the detection of the technological parameters of the slurry does not need to be repeated again, the repeated detection is avoided, the labor cost is saved, the method is simple and orderly, and the method is more favorable for accurately controlling the preparation of the blank material;

further explaining, a particle wrapping process is further included between the step (4) and the storage process, and before the particles are sent into the storage bin, powder or micro powder is adopted to produce the wrapped particles, and the moisture and the wrapping effect of the wrapped particles are detected in a sampling and plate beating mode.
