Limestone Powder Grinding Plant

About limestone powder

Limestone powder is a powdered material made from limestone through crushing and grinding. Its main component is calcium carbonate. It plays an important role in numerous fields. In the building materials industry, it is used as an admixture in concrete. In the industrial and environmental fields, limestone powder is a key raw material for the production of cement and glass. Limestone powder can also be used in agriculture as a soil conditioner.

We provide limestone powder grinding equipment and systematic solutions.

Limestone powder grinding system

Crushing: It is to break large into appropriate granularity to meet feeding requirements of raymond mill machine. The common crushing machine is jaw crusher, hammer crusher and so on.

Grinding: The small pieces of crushed limestone are sent to the silo by the bucket elevator, and then evenly and quantitatively sent to the grinding chamber of raymond mill by the vibrating feeder. It is main porocess to produce limestone powder products, according to different fineness requirements.

Powder selection: The pulverized limestone powder is graded and screened by a classifier to ensure that each particle of powder meets the specified standards. The unqualified powder will be separated by the separator and returned to the main machine for re-grinding. It is to sort out qualified limestone powder. Collect the coarse particle to return to grind again.

Packaging: Qualified limestone powder is generally stored in storage silos or packaged before it can be sold as commodities.

Limestone powder grinding mill

After crushing, grinding is an effective size reduction process to obtain limestone powder of various fineness. The popular limestone grinding mills are Ball mill and Raymond mill, HGM ultrafine mill.

Ball mill

The ball mill is also an important mill for producing limestone powder. It can grind limestone less than 25mm into powder less than 200 mesh. The limestone ball mill is economical and has high grinding efficiency.

Raymond mill

Raymond mill is an earlier and commonly used milling machine.It can grind rock with Mohs hardness ≤9.3 and humidity ＜6%.

The fineness of finished limestone powder ranges from 80 - 325 mesh, which can meet the fineness requirements in most industries.

In addition, with the development of technology, the structure and function of the Raymond mill have also been improved.
