Detailed Description

The following further describes the embodiments of the present invention with reference to the following examples and attached drawings 1.

The utility model provides a grinding and screening device for making metal powder, the power distribution box comprises a box body 1, arrange the feed inlet on box 1 in, grind structure and screening structure, it includes abrasive disc 2 to grind the structure, arrange grinding blade 3 and the first driving motor in abrasive disc 2 middle part in, be equipped with the grinding filter screen on the abrasive disc 2, abrasive disc 2 is connected through the transmission shaft with grinding blade 3, first driving motor arranges abrasive disc 2 bottom in and the output is connected with the transmission shaft, after first driving motor starts, just drive the operation of transmission shaft through the output, thereby drive the operation of grinding blade 3, grinding blade 3 carries out the fly-cutting grinding through high-speed operation to the metal block, when the metal particle that the cutting was ground out is less than the filter screen mesh aperture on abrasive disc 2, just drop to screening structure from abrasive disc 2, screening structure has included screening dish 4, the stirring roller, A second driving motor 12 and a first material collecting box 7, wherein the screening disc 4 is simultaneously provided with a screening filter screen, the mesh aperture of the screening filter screen is smaller than the mesh aperture of the grinding filter screen, in order to carry out secondary stirring and grinding on metal particles which can not be finely ground in the grinding structure through a stirring roller in the screening structure, the stirring roller is provided with two stirring rollers, namely a first stirring roller 5 and a second stirring roller 6, the second driving motor 12 is arranged outside the box body 1, the output end of the second driving motor 12 is connected with the stirring roller, the operation of the stirring roller is controlled through the driving motor, when the driving motor is started, the stirring roller can rotate at a high speed, so as to stir and grind the metal particles, when the ground metal particles are smaller than the mesh aperture of the filter screen of the screening disc 4, the metal particles fall into a first material collecting box arranged below the first driving motor, and the metal particles which can not fall into a second material collecting box 9 from a first material discharging pipeline 8, the second collection box 9 after collection can be ground again.
