Abstract
Description
Technical Field
[0001] This utility model relates to the field of epoxy zinc-rich primer production technology, specifically to a raw material grinding device for epoxy zinc-rich primer production. Background Technology
[0002] The main functions of epoxy zinc-rich primer include corrosion prevention, rust prevention, and surface protection of metals. It protects metals, especially steel structures and steel pipes, through electrochemical protection and chemical corrosion prevention mechanisms. The zinc powder in epoxy zinc-rich primer preferentially corrodes in corrosive environments, thus protecting metals such as iron from corrosion; this mechanism is called electrochemical protection. In addition, epoxy zinc-rich primer also has a shielding and corrosion-inhibiting effect, forming a dense coating that prevents harmful substances from penetrating the protected substrate. However, the production process of epoxy zinc-rich primer requires grinding the solid raw materials into powder, which necessitates specialized grinding equipment.
[0003] Most grinding devices for raw materials used in the production of epoxy zinc-rich primer currently utilize the extrusion between the grinding disc and the outer plate. A drive motor drives the grinding disc, and the grinding disc and the outer plate extrude each other to grind and crush the raw materials used in the production of epoxy zinc-rich primer.
[0004] Existing grinding devices for raw materials used in the production of epoxy zinc-rich primers have the following problems: some lack a screening mechanism, and even those equipped with screening rely on a vibrating motor and a screen, resulting in a small amplitude and insufficient separation of materials that meet the size requirements from those that do not. Furthermore, there is no dedicated material return mechanism to assist in the re-crushing of materials that do not meet the size requirements, which significantly impacts efficiency. Therefore, we propose a grinding device for raw materials used in the production of epoxy zinc-rich primers. Utility Model Content
