Marble, also known as marble, is a recrystallized limestone with the main component CaCO3. Limestone softens under high temperature and high pressure and recrystallizes to form marble when the minerals are changed. There are many colors, usually with obvious patterns and many mineral particles. The Mohs hardness is between 2.5 and 5. Marble is mainly composed of calcite, limestone, serpentine and dolomite. Its main component is calcium carbonate, accounting for more than 50%. Marble is generally soft in nature, as opposed to granite.
First stage: broken
The large pieces of marble are crushed by the crusher to the incoming fineness (15mm-50mm) which can enter the mill.
Second stage: milling
The crushed marble pieces are sent to the silo through the hoist, and then uniformly and quantitatively fed into the mill grinding chamber by the vibrating feeder for grinding.
Fine powder processing generally uses LM vertical mill, MTW European version of mill, TGM overpressure trapezoid mill; ultrafine powder processing generally uses LUM ultra-fine vertical mill, MW ring roller micro-grinding machine; sand or coarse powder The processing uses CM European coarse grinding and straight-through centrifugal grinding.
Phase III: Grading
The ground material is graded by a powder separator, and the unqualified powder is sorted by the classifier and returned to the main machine for re-grinding.
The fourth stage: powder collection
The fine powder conforms to the airflow and enters the dust collector through the pipeline for separation and collection. The collected finished powder is sent to the finished silo through the discharge device through the discharge port, and then uniformly packaged by the powder tanker or the automatic baler.
