Device for crushing and grinding uranium ores through assistance of 915MHz pulse microwave irradiation and control method

The invention relates to a device for crushing and grinding uranium ores through assistance of 915MHz pulse microwave irradiation and a control method. The device comprises five main parts of: a 915MHz microwave source generator, a microwave circulator, a water load, wave guide tubes and a microwave resonant heating cavity. After the uranium ores are irradiated by high-power pulse microwave emitted by the device, the mechanical strength of the uranium ores is reduced, the dissociation degree of the uranium ores is increased, and the crushing and the grinding of the uranium ores and the leaching of uranium minerals are facilitated. Compared with traditional continuous microwave irradiation, the pulse microwave irradiation is lower in consumption and better in assistance of the crushing and grinding effect, and can effectively prevent high-temperature sintering.
