Technical Field

[0002] Corundum powder is a kind of abrasive, the main component of which is aluminum oxide. According to the color and raw materials, corundum powder can be divided into white corundum powder and brown corundum powder. White corundum powder is white in color, has high hardness, good insulation and wear resistance, and is often used in superfine grinding and polishing in the crystal and electronics industries, as well as in the production of advanced refractory materials. Brown corundum powder is light brown in color, has high hardness and strength, and has the characteristics of impact resistance, high temperature resistance, oxidation resistance, corrosion resistance, low creep, etc. It is often used in free grinding, polishing, sandblasting and other fields, and can also be used to manufacture resin cutting discs and angle grinders. Due to its excellent high temperature properties and mechanical strength, corundum is widely used in many industrial fields such as metallurgy, machinery, chemical industry, electronics, aviation and national defense.

The curved partition plate 524 is used to block the flowing corundum micropowder particles guided by the curved stirring plate 522 and the guide groove 523 to avoid local accumulation, so that all particles have the opportunity to contact the ultrasonic energy, accelerating the corundum micropowder. The particles are crushed, and the liquid medium is contacted with the second guide ramp 65 and the curved impact plate 64 in the flowing state to guide the material to flow and impact along the slope, so that the liquid medium and the corundum micro-powder particles are close to the transducer 22, and the first guide ramp 63 and the second guide ramp 65 are distributed on the side of the energy output area of ​​the transducer 22 to assist in guiding the ultrasonic impact liquid medium, and through the rotation of the rotating shaft 512, the connecting shaft 531 and the fixed rod 532 are driven to rotate, so that the material collection folding plate 533 is rotated, and the corundum micro-powder particles are driven to flow, so as to avoid the occurrence of lower layer deposition, and the corundum micro-powder particles are dammed by the blocking groove 534 and the diverter groove 535. The particles are subdivided and diverted, and the blocking of the material collecting folding plate 533 is combined to enable the lower transducer 22 to exert impact force on the corundum micro-powder particles, thereby accelerating the crushing efficiency of the corundum micro-powder. The baffle 536 and the inclined partition 537 are used to block and limit the material, adjust the flow direction of the corundum micro-powder, force the corundum micro-powder to approach the transducer 22, and improve the crushing particle size of the corundum micro-powder particles. Combined with the continuous application of the cavitation effect, the corundum micro-powder particles are continuously refined and evenly distributed in the liquid medium to achieve the required particle size and distribution state. After the crushing is completed, the electromagnetic valves at 4 places of the discharge pipe are opened to guide the corundum micro-powder and the liquid medium out for subsequent processing.
