Is there still room for improvement in the final grinding of the vertical roller mill?

In recent years, vertical roller mill has been favored by enterprises for its relatively low power consumption, integrating grinding, drying and powder selection. It has wide adaptability to materials, fineness and convenient adjustment of varieties. Nowadays, the development trend of cement plant grinding technology with high efficiency, low power consumption, and simplified system process also coincides with the advantages of vertical roller mill. So, is there still room for improvement in the final grinding of the vertical roller mill? The answer is yes. 1. Professionals have done a lot of research on particle size matching, water demand, cement strength, unit power consumption and grain shape, and find a good technical solution suitable for cement vertical grinding and final grinding.
2. In the grinding method of the vertical roller mill, great improvements have been made to make the particle shape of the cement smaller and smaller, thereby further reducing the water demand. 3. Improve the process flow and make the variety switching faster. The process of the vertical roller mill is relatively simple, and the switching type can be completed in 15 to 30 minutes, which is faster than the roller press + ball mill. For example, Haishibang's vertical roller mill can grind slag and cement at the same time, and it can be operated in a multi-functional manner, which is impossible for ball mills and roller presses. For the future development trend of vertical grinding: 1. Multi-functional: It can realize the mixing grinding, separate grinding and product level adjustment of different materials at the same time; 2. Large-scale: The vertical roller mill will develop in the direction of large-scale grinding machine; 3. Large-scale drive equipment: The drive equipment will be large-scale, especially the large-scale, localized and internationalized main reducer; 4. The fierce competition will intensify: mainly reflected in the competition between suppliers. The promotion of new products means trial-improvement-retesting the process of repeated rotations. It is believed that the grinding industry will get better and better under the breakthrough of science and technology personnel. Shanghai Shibang Company has been committed to improving the grinding effect of the vertical roller mill, using advanced technology, advanced powder selection concepts, etc., to determine reasonable structural parameters, and strive to achieve better results.

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
