CLIRIK is a manufacturer of calcite grinding equipment. Calcite of different fineness can be used in different fields. The
HGM micro powder grinding mill, YGM raymond roller mill, CLUM ultra fine vertical mill and other equipment independently developed and produced by CLIRIK can be applied to the grinding process of calcite, and can produce calcite powder of 50-3000 mesh. In addition to grinding calcite, it can also be used to grind other ores with a Mohs hardness below 7 (like diatomite, talc, limestone, barite, quartz, etc.). It has been widely used in the industry and has a good reputation. Do you have a need for ore grinding? What are your requirements for the fineness of the finished powder?

Calcite is one of the most common natural calcium carbonate minerals, which is widely distributed around the world. Here is an introduction to the classification of calcium carbonate and which downstream application industries it is applicable to?
Heavy calcium carbonate
It is a powder product obtained by mechanical grinding of natural calcite, marble and other ores with calcium carbonate. The bulk density is generally 0.8-1.3g/cm3, and the whiteness is 89%-93%. According to the average particle size, it can be divided into:
Coarse ground calcium carbonate >3μm
Finely ground calcium carbonate 1-3μm
Superfine calcium carbonate 0.5-1μm
Light calcium carbonate
The precipitated calcium carbonate powder product obtained by the chemical reaction has a bulk density of 0.5-0.7g/cm3 and a whiteness of 92%-95%. According to the average particle size, it can be divided into:
Granular calcium carbonate >5μm
Micronized calcium carbonate 1-5μm
Fine calcium carbonate 0.1-1μm
Superfine calcium carbonate 20-100nm
Superfine calcium carbonate <20nm
Nano calcium carbonate
Superfine light calcium carbonate and ultrafine light calcium carbonate are collectively called nanometer calcium carbonate (1-100nm).
Active calcium carbonate: Calcium carbonate obtains active calcium carbonate by surface modification. The most significant difference from inactive calcium is its hydrophobicity.
What type of calcium carbonate do different industries need?
1. PVC wallpaper: 1250 mesh active heavy calcium
2. Silicone glue: superfine heavy calcium (about 2800 mesh)
3. Steelmaking: very thick stone (5-10mm)
4. ABS material: filling masterbatch (above 600 mesh, 400 mesh at the low end is also possible, depending on whether the raw material is waste or other), light calcium, heavy calcium, nano calcium can also be added
5. PP: Filling masterbatch
6. Calendering film: (powder) 2500 mesh heavy calcium/1250 mesh light calcium, the production line uses relatively coarse 325-800 mesh (granule) 400-800 mesh filling masterbatch
7. PVC edge strip: 1250 mesh heavy calcium
8. PVC leather: heavy calcium
9. PU leather: light calcium
10. Plastic bucket: PE filled masterbatch
11. Putty powder: 325 mesh light calcium (the last kind) / 800 mesh heavy calcium
12. Washing powder: 1250 mesh light calcium
13. Carpet: active light calcium + active heavy calcium (800 mesh or 1250 mesh)
14. Rubber wastewater treatment: hydrated lime
15. Stationery industry: 1500 mesh light calcium/2500 heavy calcium
16. Surgical gloves: 2500 mesh light calcium
17. Coated paper: 1500 mesh light calcium
18. Toothpaste grade: 325-600 mesh heavy calcium
19. Cable: 2500 mesh heavy calcium/nano calcium
20. Tires: light calcium (go back to do surface treatment by yourself), talcum powder (1000-1250 mesh), white carbon black (main raw material)
21. Artificial marble: 80-90 mesh
22. Coating, white paint: light calcium/heavy calcium above 1000 mesh, light calcium above 2500 mesh has better water absorption and faster drying, coating nano-calcium
23. Compound fertilizer: light calcium/heavy calcium (can be added together)
24. Soil pH adjustment: calcium carbonate (increase alkalinity), quicklime (increase acidity)
25. Resin: 2500 mesh light calcium, 1250 mesh active light calcium, adhesive nano calcium
26. PVC pipe: 1250 mesh light calcium/heavy calcium
27. PVC board: 1250 mesh active light calcium, better 2200 mesh, activation degree is about 80
28. Potting glue: 1500 mesh/2500 mesh heavy calcium
29. Rubber shoe materials, EVA shoes: 800/1250/2500 mesh heavy calcium
30. Epoxy resin: 600-1250 mesh heavy calcium (not demanding), 1250 mesh active light calcium
31. Papermaking: 400-1500 mesh light calcium/heavy calcium
32. Glass, photovoltaic glass: 200 mesh heavy calcium
33. Latex paint: heavy calcium/light calcium, few people use nano calcium, but also 6602 wet treatment of nano calcium
34. PVC rubber particles: 1250/2500 mesh heavy calcium, or 6603 nanometer calcium
