Embodiment 1
[0042] A method for processing MOX mixed particles, comprising the following steps:
[0043] (1): Ball milling treatment, the total time of ball milling treatment is 60min divided into 13 small cycles, firstly adopt the speed of 400rpm ball milling treatment for 1min, after standing for 5min, open the ball milling tank to check the state of the material, and stir the mixed material by manual stirring Processing: After stirring evenly, continue to use ball milling at 400rpm for 4 minutes, open the ball mill tank after standing for 5 minutes to check the material status, and use manual intervention to stir the mixed material; after that, the 11 small cycles are all at 400rpm, and the ball milling time is 5 minutes. Ball milling process for ball milling.
[0044] (2): Mixing treatment, add 0.05wt.% zinc stearate to the MOX mixed granules obtained in step 1 after sieving, mix them by hand and mix them visually evenly, then add them into a three-dimensional mixer at a speed of 25rp...
Embodiment 2
[0049] A method for processing MOX mixed particles, comprising the following steps:
[0050] (1): Ball milling treatment. The total time of ball milling treatment is 60 minutes and divided into 13 small cycles. First, ball milling treatment is carried out at a speed of 450 rpm for 1 minute. After standing for 5 minutes, the ball mill tank is opened to check the state of the material, and the mixed material is stirred by manual intervention. deal with. After stirring evenly, continue to use ball milling at 450rpm for 4 minutes. After standing for 5 minutes, open the ball mill tank to check the state of the material, and use manual intervention to stir the mixed material. Afterwards, the 11 small cycles all adopt the ball milling process with a rotating speed of 450rpm and a ball milling time of 5min for ball milling.
[0051] (2): Mixing treatment, adding 0.05wt.% zinc stearate to the MOX mixed granules obtained through step 1 after sieving and initially mixing, then adding to...
Embodiment 3
[0055] A method for processing MOX mixed particles, comprising the following steps:
[0056](1): Ball milling treatment. The total time of ball milling treatment is 60 minutes and divided into 13 small cycles. First, ball milling treatment is performed at a speed of 500 rpm for 1 minute. After standing for 5 minutes, the ball mill tank is opened to check the state of the material, and the mixed material is stirred by manual intervention. deal with. After stirring evenly, continue to use 500rpm ball milling for 4 minutes, open the ball milling tank after standing for 5 minutes to check the state of the material, and use manual intervention to stir the mixed material. Afterwards, the 11 small cycles all adopt the ball milling process with a rotating speed of 500rpm and a ball milling time of 5min for ball milling.
[0057] (2): Mixing treatment, after sieving the MOX mixed particles obtained in step 1, add 0.10wt.% zinc stearate for preliminary mixing and then add them to the t...
