Road marking glass beads production equipment process flow

The process flow of Road Marking Glass Beads production equipment is as follows:

1. Raw material preparation: Broken glass or glass sand is usually used as the main raw material. These raw materials need to be screened and cleaned to remove impurities. Depending on product requirements, some flux, clarifier or other additives may need to be added to improve the performance of the glass beads.

2. Melting: The prepared glass raw materials and additives are placed in a high-temperature furnace for melting. The temperature of the furnace is usually above 900℃. During the melting process, the temperature and time need to be controlled to ensure that the glass is fully melted and reaches the required viscosity.

3. Molding: The molten glass liquid is sprayed into fine droplets through a special nozzle or centrifugal equipment. These droplets are cooled in the air and form spheres under the action of surface tension.

4. Cooling: The formed glass beads need to be cooled to solidify their shape. The cooling process usually uses air cooling or water cooling.

5. Screening and grading: The cooled glass beads need to be screened and graded to remove unqualified products and classify them according to size. Screening and grading usually use vibrating screens or airflow grading equipment.

6. Surface treatment (optional): Depending on the product requirements, the glass beads may need to be surface treated, such as coating or silanization, to improve their reflective properties or adhesion.

7. Packaging and storage: Qualified glass beads can be stored and transported after packaging.

During the production process, strict quality control of glass beads' size, roundness, refractive index, reflective properties and other indicators is required to ensure that the products meet the standard requirements.

The above is the basic process flow of road marking glass bead production equipment, which may be adjusted according to specific products and equipment in actual production.
