The waste gypsum board crushing and grinding mill production line can crush waste gypsum board and waste gypsum molds into powder for reuse. The powder can be sent to the cement factory to be used as cement retarder, or it can be sent to the gypsum powder factory for processing. Construction gypsum powder creates new […]

Limestone is an ore resource with abundant reserves and widespread distribution in my country. With the rapid development of the limestone industry, limestone has a wide range of uses. It is widely used in building materials and industrial raw materials, as well as limestone powder for desulfurization in thermal power plants. How to produce desulfurized […]

Coal is produced and consumed in many countries, and coal is classified in different ways according to different purposes. The current classification method is based on the classification of coking coal, which mainly includes: anthracite, lean coal, bituminous coal, lignite, etc. The fixed carbon content in anthracite reaches 93%-98%, and the volatile matter is less […]

First, the current situation of domestic supply and demand of bauxite: Guikuang Machinery bauxite mill learned that the bauxite resources are relatively scarce, and the static guarantee period is only 10 years. Domestic resources are inherently insufficient, on the other hand, alumina production capacity continues to expand. With the large-scale increase in the demand for […]

Calcium carbonate is an inorganic compound, the main components are limestone and calcite. Calcium carbonate can be divided into two categories: heavy calcium carbonate and light calcium carbonate. Due to the nature of the particle size, crystal form, the interface is difference, its characteristics vary widely, so that the activity of calcium carbonate extends to […]

The preparation methods of slag micropowder mainly include ball mill system, vertical roller mill system and roller press system. Ball mill system investment is low, but due to its high energy consumption, high noise, and small stand-alone capacity, it is generally used for small-scale production. The roller press is a new type of energy-saving grinding […]
