Description

Technical Field

[0001] This utility model relates to the field of capacitor material grinding technology, specifically to an ultrafine grinding machine for capacitor materials. Background Technology

[0002] The dielectric properties, specific surface area, and particle size distribution of capacitor materials (such as barium titanate, alumina, and conductive carbon black) directly affect the energy storage density and charge / discharge efficiency of capacitors. Particle size influence: When the particle size of the dielectric material is ≤1μm, it can reduce grain boundary defects and improve the breakdown field strength (e.g., the dielectric constant of BaTiO3 nanoparticles can be up to 3 times that of ordinary powders). Uniformity requirements: A D50 deviation of >5% in the powder will lead to an increase in porosity after sintering, which will reduce the voltage withstand performance of the capacitor (experimental data: for every 1% increase in porosity, the ESR increases by about 8%).

[0003] Existing grinding machines are inconvenient to use because of the feeding location, and collecting materials after grinding is also inconvenient. In addition, the grinding efficiency is low. Utility Model Content

At this point, the capacitor material will enter between the upper and lower grinding discs. Releasing the horizontal plate moves the guide rod and conical plate upwards, resetting and sealing the feed pipe. Then, releasing the pressure plate causes the lower grinding disc to reset.

If it is necessary to remove the ground capacitor material, remove the baffle inside the collection tray and then scrape the capacitor material out of the collection tray, thus achieving the effect of convenient removal of capacitor material.
