Calcium carbonate (CaCO3) is one of the most important, versatile and – in terms of quantity – one of the most frequently used minerals. It is used throughout the world, for example, in the plastics, rubber, foodstuffs, chemicals and pharmaceuticals industries. It is an important constituent of high-grade paper, for which typical finenesses that range between 60 and 99% < 2 µm are demanded.
calcium carbonate grinding process
We 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.
Calcium carbonate -> vibrating feeder -> ball mill -> vibrating screen -> MTW trapezium mill -> vibrating screen -> belt conveyor -> product
In short, using our products to produce calcium powder in large scale has the advantages of feasible technique, stable operation, high economic index, good application value. The grinding process is also suitable for other low hardness of non-metallic mineral such as: talc, kaolin, quartz, feldspar, mosquito stone snake, alumina ,etc.
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
