Marble Features

Mohs’ hardness:2.5-5
Marble is a kind of recrystallized limestone and its composition is CaCO3 (50%), which have variety of colors, usually with distinct patterns and many mineral grains.
Limestone softens under high temperature and pressure re-crystallizing to form marble as the minerals change.
The leftover material of marble has high secondary use value, which can be processed into fines and widely used in the chemical industry.

Marble processing technology

1. Breaking stage: The bulky ore is broken by the crusher to a fineness of 15-50mm (Mill feeding standard), if the leftover material meets the feed size requirements, no breakage is required.

2. Milling stage:The qualified materials enter the mill grinding chamber uniformly and quantitatively through the feeding system to grind into powder.

3. Grading stage: Under the action of airflow, the material after grinding will enter into classifier to classified, the unqualified powder will be returned to the grinding chamber for re-grinding.

4. Powder collection stage:The powder conforming to the fineness enters the powder collection system along the airflow through the pipeline, and the gas powder is separated, and the finished product will be send to the finished product bin by the conveying device.Then use powder tanker or automatic baling machine for packaging.
