Zinc powder pigments have two particle structures: spherical and flaky. Flaky zinc powder has greater hiding power. Zinc powder is chemically active. In air at room temperature and under normal conditions, a thin, dense film of basic zinc carbonate forms on its surface, preventing further oxidation. This gives it considerable corrosion resistance in the atmosphere, but it is not resistant to acidic and basic salts. It is soluble in inorganic acids, bases, and acetic acid, but insoluble in water. Zinc powder burns in pure oxygen, emitting white light, but is difficult to burn in normal air, so it is not considered a flammable solid.
Zinc ore grinding requires a reliable Raymond mill. This mill maintains a feed particle size below 2 cm and an adjustable discharge size between 50-600 mesh. Normal production typically requires a zinc ore powder fineness of 100-200 mesh, making it easy and simple to grind zinc ore using a Raymond mill. There are many Raymond mill models available, and you can choose the one that best suits your production needs. Large equipment isn't essential; you can choose a suitable Raymond mill based on your terrain, power supply, financial resources, and production capacity.
