| titleOfInvention | Preparation device and preparation method of radioactive uranium ore standard substance |
| abstract | The invention belongs to the technical field of standard substance preparation, and particularly relates to a preparation device and a preparation method of a radioactive uranium ore standard substance. The device comprises an electric control cabinet, a feeding tank, an electric conveying system, a material throwing box, a ball mill, a material discharging box and a working motor: throw the material jar and be used for holding the standard substance candidate sample after the coarse crushing, automatically controlled cabinet control electric conveyor system will throw the material jar and move to the nested ball mill top in throwing the workbin inside, and standard substance candidate sample is shifted to the ball mill by throwing the material jar, and the work motor provides power supply for the ball mill, goes out the workbin and connects and be used for holding the standard substance that the preparation was accomplished in throwing the workbin lower part. The method comprises the steps of drying, coarse crushing, feeding, grinding and mixing, throwing, unloading and the like. The method has the characteristics of automation, no pollution, no dust damage to workers, low cost and high grinding efficiency, and the prepared standard substance can accurately represent the natural characteristics of the substance. |
