The mixing machine adopts a double-drum mixing method. First, the abrasive and the liquid are mixed in the upper drum, the resin powder and other various auxiliary materials are mixed in the lower drum,then the mixed abrasive is slowly poured into the lower pot and mixing again (lower drum no stop). Each mixing drum has a separately mixing device (including mixing knife, flying knife and scraper). The mixing knife rotates and the drum rotates with frequency conversion speed regulation, which strengthens the mixing effect and improves the quality and efficiency of the mixing.
