The invention discloses a preparation device of ultra-low AI
silicon micro-
powder. The preparation device comprises a
drying kettle, a
chassis and a feeding frame; the
drying kettle is fixedly installed on one side of the top of the
chassis through a supporting rod; two sets of
grinding discs are installed in the
drying kettle; a
grinding chamber is welded to the top of the drying kettle; two setsof
grinding rollers extending into the grinding chamber are fixedly installed on the back face of the grinding chamber through a transmission frame; a feeding frame is movably and fixedly installed at the top of the
chassis through a supporting frame; and one side of the feeding frame is connected with the grinding chamber through a connecting
pipe. According to the preparation device of the ultra-low AI
silicon micro-
powder provided by the invention, two groups of grinding discs are mounted to quickly
grind silicon, the working efficiency of the device is improved, the grinding effect of thedevice can be improved through simultaneous grinding of the two sets of grinding discs, feeding of the device can be facilitated through the mounting of the feeding frame, the feeding efficiency of the device is improved, the working efficiency of the device is improved, manual feeding of workers is not needed, and the
workload of the workers is reduced.
