Vertical grinding limestone grinding production process and environmental protection measures

1. Production process of limestone in vertical roller mill grinding production The source of limestone is generally a large-scale mine. After the blasting of the mine, the falling bulk material passes through the crushing action of the crusher, and then through the grinding effect of the vertical roller mill, the limestone powder for industrial use is obtained, so the production process and its The crushing and grinding are inseparable. After the blasting, the large limestone material needs to be crushed by the crusher, and the crushing equipment is broken, broken, etc., and the limestone crushed by these crushers will become small pieces of material, and these small pieces The material can be put into the mill for milling. The crushed limestone will be transported to the silo by the hoist and then transported to the vertical roller mill mainframe by the closed dosing machine. The limestone powder after the main mill grinding will be blown in the hot blast stove. The hot air of the system is blown to the classifier. After the powder selection by the classifier, it is collected by the dust collector to obtain the finished Limestone Mill material
In the production process described above, the flow direction of limestone and the fineness of limestone material are the same, and these are the same processes as those of vertical roller mill in limestone milling. 2. What environmental protection measures have been taken in the production of limestone milling? In the case of regular limestone crushing and milling, in order to protect the environment, sometimes in order to prevent noise pollution, two devices will be installed to prevent dust and noise pollution. Regarding the dust problem, two kinds of dust collecting devices, such as a dust collector and a dust collector, are installed in the milling production line. The function of the dust collector is to collect the powder material, and the dust collector is installed behind the powder collector, and it is used in addition to In addition to collecting powder materials, it also prevents the powder material from leaking into the air. As for the noise problem, it is only necessary to install two mufflers in the production line.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa...

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range...

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands...
