Description
Technical Field
The method relates to a method for judging a dry ball milling end point, in particular to a method for judging a dry ball milling end point of nuclear-grade oxide powder.
Background
When the materials are crushed by the dry ball milling, the materials are crushed and refined to a certain critical granularity under the influence of the crushing performance, the agglomeration capacity, the equipment structure and the performance of the materials, namely the materials are not refined after the ball milling is finished, most of energy generated by the ball milling is converted into internal energy, the temperature of the materials is increased, and the phenomena of hardening and even welding into large particles occur. The phenomenon is more obvious in the ball milling process for preparing MOX fuel due to the high moisture absorption and high viscosity of uranium and plutonium metal oxides. After the ball milling end point is reached, the ball milling time is too long, the mixed MOX powder is seriously hardened, uranium and plutonium metal oxides are easily insufficiently refined and unevenly mixed, the screening is difficult, and the subsequent pellet preparation process and the qualification rate and the performance of products are directly influenced. Therefore, in order to ensure the quality of the MOX powder ball milling process, the ball milling end point needs to be determined in time, and the hardening of materials due to ineffective ball milling is avoided.
At present, an end point determination method is still lacked for dry ball milling, particularly dry ball milling of nuclear-grade oxide powder, and a proper auxiliary determination means and technology are also not available.

The technical scheme of the invention is as follows: a method for judging a dry ball milling end point is characterized by comprising the following steps: the method comprises the following steps:
s1, arranging a temperature measuring contact A on the side surface of the ball milling tank, arranging a temperature measuring contact B on the bottom surface of the ball milling tank, wherein the temperature measuring contact A and the temperature measuring contact B are both connected with a temperature display, and the temperature display realizes the alarm function;
s2, when the environment temperature is 15-30 ℃, if the temperature measuring contact A and the temperature measuring contact B reach the end point alarm temperature at the same time, the temperature display starts to alarm;
and S3, observing the heating rate of the tank body when the temperature display gives an alarm, and if the heating rate is more than 1.5/min, indicating that the ball milling end point is reached.
