Ore mill takes you to analyse the structural composition and application of limestone

Limestone in nature is the most common, hills and rivers can be seen everywhere, but limestone due to the external environment and different geological factors in nature to show the situation is also different, a variety of different structural properties of limestone mining and the use of crushing and milling equipment is also different, generally the most commonly used ore mill, jaw crusher, sand making machine and so on.

Limestone according to different causes can be divided into granular limestone, biochemical limestone and bioskeletal limestone, according to its structural structure can be divided into bamboo leaf limestone, oolitic limestone, leopard skin limestone, clumped limestone, etc., due to different structural structure to the existence of different situations, hardness, humidity size, etc., according to the different regions of different structure of the rock in the selection of processing equipment need to pay attention to, some limestone properties Some limestone nature of the need for crushing equipment better choice of jaw, cone crusher, VSI sand making machine, etc., while some rocks are soft and easy to process with hammer crusher, impact crusher can be completed, as for limestone powder processing grinding equipment for its hardness of 9 or less can be suitable. For example, limestone stone production line, the nature of the hardness of the original equipment configuration should be selected vibrating feeder, jaw, cone, vibrating screen, belt conveyor, etc., while the softer original cone broken into impact broken can also be, after all, there is a certain disparity in price between the two, while the individual small stone processing, the selection of a hammer broken or heavy hammer broken can also be completed, and equipped with other equipment, and the most commonly used in the artificial powder equipment is the raymond machine, High-pressure mill, European version of the mill and so on.

Limestone development and use process from calcium carbonate to calcium oxide to calcium hydroxide process, each state of limestone has its different uses, calcium carbonate ore can be directly used can also be processed and applied, for example, power plant desulphurisation is limestone is currently a large amount of projects, calcium carbonate can be used for flue desulphurisation after Raymond mill grinding, and after high-temperature calcination of calcium carbonate effect is higher, the limestone calcined to a temperature of 1000 ~ 1300 ° C, it can be used for the production of calcium carbonate, calcium carbonate and other calcium carbonate. 1300 ° C, can be CaCO3 in the CO2 discharge, generate lime calcium oxide, the same amount of calcium oxide desulphurisation effect is more thorough, furnace, flue desulphurisation are suitable, but the calcination process of limestone requires calciner and other processing equipment, the cost will have a certain increase in calcium carbonate, calcium oxide can be used with the same kind of milling machine processing.

Another important use of limestone is the application in construction projects, such as concrete mixing plant, cement production line, paint and so on. Concrete mixing plant can be used to grind raw ore directly, the stone is the choice of jaw crusher, impact crusher, sand maker and other corresponding crushing and sand making equipment; cement production line on the quality of the separation of higher requirements, the fineness of the finished material, the degree of uniformity of the quality of the cement has an important impact on the selection of grinding equipment is better to use the new Raymond mill and other advanced equipment; the application of the paint can be used to choose the mill can also be optional, calcium oxide in contact with water will be turned into calcium hydroxide, into a fine, smooth, and smooth. Calcium oxide in contact with water will become calcium hydroxide, into a delicate paste, can be used after processing by the filtering device, but selected in the renovation industry on the high quality requirements of the paint, the traditional lime pond production process is more cumbersome, and temporary use of a large number of construction sites, so the application of limestone in the paint is generally also processed by the Raymond machine processing and processing after the use of limestone.

Limestone is only a large amount of natural environment and the most common type of ore, other mineral resources are also so, so when the user just provide the name of the material when the mill manufacturers must not be in a hurry to equip with its equipment, and should be a detailed understanding of the composition of the structure, geological characteristics of the judgement, mining equipment, in-depth analysis of the structure of the rock, to bring people to understand in-depth, the rock also help a variety of crushing and grinding machines to achieve their own value.

Crusher, mill and other equipment model type selection is more cumbersome and complex, in order to better help customers to solve equipment selection and other technical problems, our company has set up a professional and technical customer service 24 hours a day to serve you, click on the web page customer service immediately chat online.
