[0002] Heavy calcium carbonate, or simply calcium carbonate, is made by grinding natural carbonate minerals such as calcite, marble, and limestone. It is a commonly used powdered inorganic filler with advantages such as high chemical purity, high inertness, low chemical reactivity, good thermal stability (it does not decompose below 400°C), high whiteness, low oil absorption, low refractive index, softness, dryness, absence of crystallization water, low hardness, low abrasion value, non-toxicity, tastelessness, odorlessness, and good dispersibility. Due to varying needs in different fields, heavy calcium carbonate is sometimes pulverized using a side-mounted mill to produce ultrafine heavy calcium carbonate.

[0003] Current side-mounted mills for ultrafine grinding of calcium carbonate often require manual material return to achieve multiple grinding processes. Utility Model Content

Driven by the first auger, it is filtered through the filter plate. The ultrafine heavy calcium carbonate that meets the standard is discharged through the filter holes of the filter plate, while the non-standard heavy calcium carbonate falls into the second connecting pipe driven by the first auger.
