What equipment is used to process minerals into pigments

Minerals are the monomers of natural elements and their compounds formed in various geological actions, which are the basic units of rocks and ores. Natural mineral pigments are made from natural ores through beneficiation, crushing, grinding, grading and refining. What equipment is used to process minerals into pigments?

Hematite pigment production process: choose hematite ore with grade above 56% and red color, use hammer crusher to crush the raw ore to 2-3mm first, then grind it to 200 mesh by ore mill to account for 60% of the total, and then carry out shaking table beneficiation, and then finely grind the selected concentrates to 1250 mesh, and then dry and crumble the pigment as iron red pigment (Fe2O3). This method is also applicable to the following common mineral pigments:

1. red mineral pigment: cinnabar, hematite (iron oxide red Fe2O3) is the main.

2. Yellow mineral pigment: earth yellow (i.e. limonite, yellow, brown, brown-black to reddish brown), andromeda, orpiment, gold.

3. Blue natural mineral pigment: lapis lazuli, containing pyrite, hardness is 5.0 to 5.5, the color is medium to deep slightly greenish blue to violet blue; stone green, a kind of blue copper ore, hardness is 3.5 to 4.

4. green natural mineral pigments: malachite, one of the copper ore, the color of emerald green, grass green, dark green. Turquoise, dark and light, green and blue, similar to the cool "mint green".

5. Other mineral pigments: white pigment titanium dioxide, zinc barium white; black pigment carbon black, iron black (Fe3O4); yellow pigment lead chromium yellow (PrCrO4), etc.; body pigment calcium carbonate, talc and so on.

Mineral pigments have been widely used in filling and coloring of fine arts, paints, cosmetic production and industrial manufactured products. As a high-quality mining equipment manufacturer for more than 30 years, we produce Raymond mill, European mill, suspension mill, ball mill, hammer mill and other mineral grinding and crushing equipments, which are able to process all kinds of mineral ores such as iron ore, copper ore, titanium dioxide, calcium carbonate, talcum powder and so on, and customize the equipment configuration plan suitable for the user according to the user's actual situation.
