Heavy calcium carbonate is obtained by directly crushing natural calcite, limestone, marble, chalk, shells, etc. by mechanical methods. Because its sedimentation volume (1.1-1.9mL/g/g) is smaller than that of chemically produced light calcium carbonate (2.4-2.8mL/g), it is called heavy calcium carbonate. 325 mesh heavy calcium carbonate powder uses 1. Use in the coal-fired power plant industry […]

Gypsum is a very important mineral material in the industrial field and is often used in the construction field. Gypsum can be divided into natural gypsum and industrial by-product gypsum according to its type. The two kinds of gypsum are very different.

In the process of stone processing, it is unavoidable that waste gravel and waste mud will have an impact on the environment, and lead to the waste of soil resources and the deterioration of the regional air environment. Therefore, the recycling of stone waste generated in the stone processing process has attracted increasing attention. As […]

Lignite also known as firewood coal is a mineral coal with the lowest degree of coalification. It is a brown black, lusterless low-grade coal between peat and bituminous coal. Strong chemical reactivity, easy weathering in the air, not easy to store and transport. Because it is rich in volatile matter, which is up to more […]

In the hydrated lime production process line, it is necessary to equip the grinding equipment at the output end of the quick lime digestion system, so as to grind the semi-finished hydrated lime into finished hydrated lime with target particle size. Then, Does the hydrated lime could be ground by Raymond Mill? In order to […]
