Marble, also known as marble, is a recrystallized limestone whose main component is CaCO3. There are many colors, usually with obvious patterns and many mineral particles. The Mohs hardness is between 2.5 and 5.
Marble Processing Technology
- Crushing: Large pieces of marble are crushed by the crusher to the fineness of the feed marble (15mm-50mm) that can enter the mill. If the marble scrap meets the feed size requirements, no crushing is required.
- Grinding: Small pieces of marble that meet the conditions for entering the mill are uniformly and quantitatively fed into the grinding chamber of the mill through the feeding system, and ground into powder in the grinding cavity.
- Classification: the ground marble will be classified by the classifier along with the airflow of the system, and the unqualified powder will be classified by the classifier and then returned to the main grinding cavity for re-grinding.
- Powder collection: The powder that meets the fineness enters the powder collection system with the air flow through the pipeline, and the gas and powder are separated. The finished powder is sent to the finished product silo by the conveying device, and then is packaged by a powder tanker or an automatic baler.
