Ground limestone has a wide range of applications in different industries.

The large - sized limestone raw materials are fed into the jaw crusher for primary crushing to reduce the particle size to a level that can be fed into the subsequent grinding equipment. Then, the crushed limestone is transferred to the grinding mill. During the grinding process, strict control over factors such as the feeding speed, grinding pressure, and air volume is necessary.

For example, a proper feeding speed ensures a continuous and stable supply of materials for grinding, while the right grinding pressure can improve the grinding efficiency and the fineness of the product. The air volume affects the transportation and classification of the ground limestone powder.

Applications of Ground Limestone
 

In the construction industry, it is an essential raw material for manufacturing cement. Limestone accounts for a large proportion in the raw material composition of cement production. During the cement - making process, limestone is burned with other raw materials such as clay at high temperatures to form cement clinker, which is then ground into cement powder. In addition, ground limestone can also be used as a filler in concrete, improving the workability and durability of concrete.
 

In the chemical industry, it is used as a desulfurization agent in flue - gas desulfurization systems for power plants and industrial boilers. Limestone reacts with sulfur dioxide in the flue gas to form calcium sulfate, effectively reducing sulfur dioxide emissions and protecting the environment. It is also used in the production of calcium - based chemicals, such as calcium carbonate, calcium hydroxide, etc.
 

In agriculture, ground limestone can be used as a soil amendment. It can neutralize acidic soil, adjust the soil pH value, and provide calcium and magnesium elements for plants, which is beneficial to the growth and development of crops.
