Zinc ingot chip cutting machine cuts zinc ingots to chips, then granulator grinds them into particles or powder. Zinc powder can be used for dry batteries, metal coating, paints, etc. Our machine do rough grinding for industrial mass production, to get finer powder, you need to grind the particles for several times.

Introduction of zinc powder

Zinc powder, pure zinc is gray metal with metallic light. The raw material used in the manufacture of zinc powder is metallic zinc ingot with the grade ZN-4. 99.5% purity.

Application

(1) Steel anticorrosion Zinc powder is widely used in the field of anticorrosion. The anticorrosion of steel components is the most important use of zinc metal, and the coating methods include hot-dip plating, electroplating, thermal spraying, zinc-rich coatings, powder plating, etc., of which hot-dip plating is the main method. Zinc-rich coatings are mainly used for coating large steel components that are not suitable for hot-dip plating and electroplating, such as large outdoor steel structures (ocean engineering, bridges, pipelines, etc.), ships, containers, and so on.

(2)Chemical production Widely used in the production of sodium hydrosulfite (Na2S2O4), Lithopone, rongalite(CH3NaO3S), dye intermediates, etc., as a reducing agent, whose particle size is slightly coarser than that of paint zinc powder, and the average particle size of zinc powder for general chemical use is 6 ~ 9μm.

Difference between zinc dust and zinc powder

Zinc dust is essentially nothing else but minute physical particles of zinc (between 2.5µ to 9.0µ).  It can be used for a variety of purposes, most of them are those where zinc is used. Some of the purposes are paints, electrometallurgy, explosives, zinc dust distillation, etc. Zinc powder, also known as zinc granules, is a bluish-gray colored, pure metal powder with particle sizes above 9.0µ. It’s mainly used in galvanizing as an anti-corrosion substance in steel; in die casting of precision components; in making brass; in making paints; in medicine and cosmetics; and as micro nutrients for animals, plants and humans.
