1. Introduction Dolomite is a carbonate mineral with chemical formula: CaMg(CO3)2. Its crystal structure is like calcite, often in the form of rhombohedron. Pure dolomite is white, but due to the presence of other elements and impurities, it sometimes appears […]

Introduction Activated carbon is a specially treated carbon. Through heating organic raw material (coal and wood, etc) in an air-tight environment can reduce non-carbon components. This process is called carbonization. And then react heated organic raw material with gas to produce product with a  well-developed

In the field of powder processing, ball mill-classifier production line is a commonly used production process. It consists of two main equipment: ball mill and air classifier. The ball mill can grind raw material to required fineness, while air classifier can classify the ground

Quartz is a mineral resource with stable physical and chemical properties. It has important application value in building materials, and it can be used as concrete admixture, artificial marble and road construction material, and glass raw material. The application of quartz

1. Introduction Non-woven fabric is made of man-made fibers. In recent years, with characteristics of moisture-resistance, lightweight, non-toxicity and low cost, non-woven fabric has gradually come into people’s view and has been widely used in many fields. Ultra-fine calcium carbonate, as a widely used

1. Introduction of calcite Calcite is a calcium carbonate mineral, the main component of which is CaCO3. It is usually transparent, colorless or white, and sometimes contains mixed colors. Its Mohs hardness is 3, density is 2.6-2.94, and it has
