Sand and gravel industry bigger and stronger in China

Sand industry as an important part of national economic construction, has no alternative, construction, infrastructure, transportation construction is inseparable from the sand, the reform and opening up 30 years, sand and gravel as an important one of the basic materials of construction industry in our country, made important contributions to national infrastructure construction, promote fast development of national economy. At present, the sand industry has formed a 300 billion yuan market size, directly or indirectly boost the development of related industries, transportation industry alone drive to produce the economic benefits of nearly 200 billion yuan. The development of sand industry, directly promote the rapid growth of GDP, created a large number of employment opportunities for the society, made outstanding contribution to the national economy development. China gravel association also accompanied the pace of reform and opening to the outside through the 30 years, the China association of sand and gravel on the 30th anniversary of the symposium, China building materials federation President Joe fong kuo could point to ways to sand mining industry in our country is still backward, and needs to improve technology level. Due to mining method is relatively backward, industry in mining efficiency, labor productivity is still relatively low, the particle size standards, environmental protection need further enhance and improve, affect the development of sand industry as a whole benefits. Developed the third Sand making machine, suitable for sand stone material crushing. Developed by the new impact crusher is widely used in sand and gravel industry such as finely homework, product grain shape is a cube, the needle flake content is low, the mechanism of building sand, stone and a variety of metallurgical slag is widely used in crushing, compared with other types of crusher production efficiency is high. Shanghai is as high as the research and development of the third create sand machine has stable and reliable work, convenient maintenance, high production sand rate, etc. Sand industry want to the next level, you must upgrade mining way, accelerating technological innovation, change the way of management, improve the efficiency. http://www.quarrycrusher.cn/product/b-deep-rotor-impact-crusher.html

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...
