calcium carbonate grinding mill

Calcium carbonate application
Calcium carbonate is a kind of inorganic compounds, lime rock (abbreviation limestone) and calcite's main ingredient. According to the calcium carbonate production method is different, can be divided into carbonate heavy calcium carbonate, light calcium carbonate, etc. Heavy calcium carbonate (known as fly powder) it is to use mechanical method (using raymond grinding mill or other high-pressure grinding machine) direct crushing natural calcite, limestone, such as chalk, shells can be made.

Calcium carbonate grinding mill machine:

Calcium carbonate powder is an important material in many industries. So the calcium carbonate powder making plant is widely used in many countries.
SBM can design and supply the whole unit of calcium carbonate grinding mill plant to produce calcium carbonate powder from coarse powder to fineness powder. Our grinding mill plant can grind the calcium carbonate under the size of 2mm, the final grain size of calcium carbonate powder can be down to from 600 micron till 5 micron in diameter according to powders' usage.
The feed material is fed pneumatically into the grinding mill. The particles are pulverized by a high speed agitated grinding media. The grinding media can be stainless steel, chrome steel, alumina or zirconia. The micronized particles are entrained in the air stream and exit the mill in a high efficiency air classifier. The on size particles are separated and the oversize returned to the mill for regrinding.
The process for fine ground and ultrafine ground calcium carbonate produced in a ultrafine dry grinding mill in closed circuit with a high efficiency air classifier.
This grinding process is suitable for calcium carbonate, marble and limestone grinding down to 1 micron average particle size.
