Analysing the crushing and grinding process of limestone by its different uses

Limestone is the most common in nature, and most of the stones in the mountains contain calcium carbonate, so they can all be limestone, also called lapis lazuli. Limestone is a major building material, but also chemical, pharmaceutical, cosmetic, feed and other industrial raw materials, according to its different uses, the required lime particle size also varies, need to be crushed, grinding production line to complete the crushing equipment is not more, the general crusher are available, but grinding according to the specific requirements of the fineness of the slight difference in the most commonly used Raymond Mill, Ou version of the mill, mill, such as micronized powder mill.

1. Limestone in the road and bridge generally appear as a foundation stone, its fineness is not very high, 1-2mm, 2-3mm, 3-5mm granular particles are the most widely used, stone production line first by the jaw crusher for primary crushing, and then there is an impact crusher secondary crushing, and then through the vibrating screen for screening. For example, the particle size of 450mm limestone processed into 5mm finished material, the output of 15 tonnes per hour, a complete set of production equipment: vibrating feeder (420x110), jaw crusher (600x900), high-efficiency fine crusher (1400x1400), belts, etc., because of the fineness of the finished material is less than 5mm, and then in the choice of fine crusher rather than other crushing equipment.

2. particle size and then some of the finer known as sand, mostly used in construction materials as concrete aggregate, this fineness of limestone is more special, PCL sand maker can be used as processing equipment, grinding mill can also choose to use, so the range of choices is also relatively wide, the specific needs of more users of the material's specific requirements.

3. Limestone uses the most or between 200-300 mesh powder, wall coatings, chemical power plant desulfurisation, feed, medicine, etc., Raymond mill grinding range between 30-425 mesh, so Raymond mill most commonly used grinding equipment, but some powder manufacturers yield requirements are very high, high-pressure mills, European-style mills compared to the same type of Ray mill output will be much higher, so large powder processing plant to select the High mill, European limestone mill. For some special industries, such as pharmaceuticals, cosmetics and other high fineness requirements, no requirements for production, you need to choose micro powder mill, ultrafine mill and other special grinding equipment. Different uses, equipment selection production process is also different.

The application of limestone has a long history, the Ming Dynasty Yu Qian in the poem "Lime Yin" has long mentioned limestone out of the mountains, burning, forging and grinding process, nowadays the production process has been very mature, OCP in the mining industry for many decades, put into production and research for more than thirty years, regardless of the crushing equipment, or grinding mill production process in the same industry belongs to the advanced and leading technology, in the process of continuous development, innovation, quality first is the enterprise The company's philosophy is always the same.
