The laboratory basket Grinder consists of a frame, a rotating shaft, a pump blade, a grinding disc dispersion disc and a grinding basket filled with beads. In the working state, the grinding basket is stationary. The rotating shaft is equipped with a pump blade, a grinding disc and a dispersing disc. The dispersing disc rotates at a high speed, which generates negative pressure and strong suction force between the bottom of the grinding basket and the dispersing disc. The material in the basket is sucked out. At the same time, the pump blade installed on the upper part of the grinding basket pumps the base material to be ground into the grinding basket. The high-speed rotation of the dispersing disc below the grinding basket pre-disperses the grinding base material. The grinding disc and grinding beads are The grinding basket is pushed to grind the base material. The screen at the bottom of the basket separates the particles from the base material. The pump blades and dispersion discs in the grinding basket ensure smooth flow, so the desired grinding effect can be obtained in a short time. .
