Technical Field

The invention belongs to the technical field of machinery, relates to a glass particle preparation device and an operation method thereof, and particularly relates to a special-shaped glass particle preparation device and an operation method thereof.

Background

When raw materials of glass beads with high refractive index are manufactured, a water quenching mode is generally adopted, namely molten glass liquid with low viscosity and high temperature is directly put into water, the glass liquid is cooled and solidified to form small glass particles, then the small glass particles are dried, and finally the small glass particles are crushed to obtain glass bead raw material powder with certain particle size distribution. However, the water quenching process generates a large amount of glass filaments with diameters less than 40um and glass flakes with thicknesses less than 40um, so that subsequent pulverization processing generates more ultrafine powder, and the yield and production efficiency are reduced. Meanwhile, as the molten glass is directly contacted with cooling water, the post-process processing can be carried out only by adding a drying process, and the production energy consumption is increased. In the design and construction of new materials, some special-shaped glass particles are often needed to meet certain optical performance requirements. However, these glass particles with special shapes are difficult to obtain by using a common method, and a device for preparing the glass particles with special shapes and an operation method thereof are urgently needed in the prior art.
