What equipment is needed to grind limestone into ultrafine powder of 3,000 mesh?

What equipment is suitable for grinding limestone into ultrafine powder of 3,000 mesh? 3000 mesh is considered an ultra-fine powder in terms of particle size. It is difficult to achieve this fineness with an ordinary mill. Limestone grinding ultrafine powder 3000 mesh equipment is recommended to continue reading below.

Limestone is a common non-metallic mineral with widely distributed resources and abundant reserves, especially in the south. It is the main rock structure mineral. The main component of limestone is calcium carbonate. Calcium powder can be made by directly crushing and grinding limestone. However, limestone raw ore generally has more impurities and low calcium content, so the whiteness is average. There are very few raw ores that are particularly white. Most of them are Slightly bluish gray. This kind of medium and low-grade limestone is not recommended for grinding into ultra-fine powder. It is suitable for grinding into coarse powder. The market competitiveness of ultra-fine powder is also weak. If it is high-quality limestone, you can consider grinding it into ultra-fine powder, but it is rarely ground as fine as 3000 mesh, usually 400/600/800 mesh. The raw ore for producing 3000 mesh ultra-fine calcium powder is mainly high-grade calcite or marble, which requires high whiteness and high calcium content. Only in this way can the calcium powder products produced have competitive advantages and can create value.

However, many customers still come to inquire about what equipment to use to grind limestone into ultra-fine powder of 3,000 mesh. Dry grinding to 3000 mesh is a relatively fine particle size, which cannot be achieved by ordinary Raymond mill or coarse powder vertical mill, so an ultra-fine vertical mill is required. This is an equipment suitable for the large-scale production of ultra-fine calcium carbonate, which is based on the coarse powder vertical mill and has made many upgrades for ultra-fine powder processing, especially the upgrade of screening technology. This equipment has stable performance, saves energy and reduces consumption, and has high screening accuracy. It has been successfully used in calcium carbonate projects.

Finally, let’s introduce the industries in which limestone grinding ultrafine powder 3000 mesh is mainly used. This involves the downstream high-end applications of ultrafine calcium carbonate. It is mainly used in high-end rubber and plastics, coatings, papermaking and ink, medicine, biology and other fields. The demand is not large, but the unit price of the finished product is relatively high.

Limestone grinding to ultra-fine powder of 3000 mesh is generally not recommended, but if the raw limestone ore is of really high grade, it can be used to make such high-end mineral products.
