Mechanical and electrical products manufacturers expand new industrial space, transform green growth

mechanical and electrical products manufacturer Zoomlion revealed on the 20th that an environmental protection production line that can produce 150 tons of high-quality machine-made sand per hour has recently been put into operation in Jishou, Hunan Province. This is the world's first 150 ton building type dry sand making system of Zoomlion, which has been officially put into operation. It is also regarded by the industry as the "masterstroke" of Zoomlion's transformation and diversified development. As Zhan Chunxin, chairman of Zoomlion, said, "China's economy is in transition, the global economy is moving towards green growth, and the construction machinery industry has entered an era of efficiency and quality."

Zoomlion, a manufacturer of mechanical and electrical products, revealed on the 20th that an environmental protection production line that can produce 150 tons of high-quality machine-made sand per hour has recently been put into operation in Jishou, Hunan. The system has applied for more than 20 national patents and has a number of independent intellectual property rights

the production line can produce high-quality machine-made sand around the clock, and the fully enclosed structure ensures zero pollution emission. According to the evaluation of insiders, this is a major technological innovation in China's sand and gravel equipment industry, which is at the top level in the field of global sand and gravel equipment, and is expected to change the situation that traditional sand mining and sand making destroys the ecological environment and dust pollution is difficult to control

this is Zoomlion's first 150 ton building in the world. The collected experimental data will be converted into image information faster, and the dry sand making system will be officially put into operation. It is also regarded by the industry as Zoomlion's transformation and pursuit of diversified development. As Zhan Chunxin, chairman of Zoomlion, said, China's economy is in transition, the global economy is moving towards green growth, and the construction machinery industry has entered an era of efficiency and quality

according to experts in the industry, high-quality machine-made sand can replace traditional aggregate for concrete production, and can provide concrete strength and various indicators on the premise of reducing the amount of cement, so as to strengthen the quality and service life of housing construction, reduce carbon dioxide emissions and haze

according to the data, the consumption of concrete in China is close to 60% of the world's annual output. As the most important raw material of concrete, the next three to five years will be a steady growth trend. The consumption of sand and gravel aggregate is huge, with an annual output of more than 10 billion tons and an industry scale of more than 500 billion yuan. However, natural sand and gravel aggregate is facing the problems of increasing shortage of resources, soaring prices and prominent contradiction between supply and demand; The traditional mechanism has poor sand shape, which is difficult to meet the relevant national grading standards, and has been accused by industry experts as a bottleneck restricting technological progress, which has become the culprit affecting the quality of concrete

at the social level, high-quality machine-made sand is green, environmental friendly, resource-saving, and can significantly reduce the toxicity and biocompatibility of materials. Biocompatibility refers to the interaction between materials and human body to produce various complex biological, physical and chemical reactions to improve the quality of buildings. In 2013, the national commercial concrete reached 2billion cubic meters. If all high-quality machine-made sand is used, 100 million tons of cement can be saved every year. If calculated at 300 yuan per ton of cement, Brazil, which is in the midst of the world cup, can save 30billion yuan for the whole industry. Each ton of cement requires 0.14 tons of standard coal and generates 0.7~0.8 tons of carbon dioxide. If all high-quality machine-made sand is used, 14million tons of standard coal can be saved every year and 70million to 80million tons of carbon dioxide emissions can be reduced

from the perspective of the industry, the equipment upgrading of the gravel industry, through the introduction and vigorous promotion of high-quality machine-made sand production lines, will significantly promote the equipment upgrading of the gravel industry, gradually change the traditional backward production methods, and accelerate the standardization and normalization of the development of the gravel industry. On the other hand, at present, there is overcapacity in the domestic commercial and mixed industry, the cost of raw materials continues to rise, competition is intensifying, and the profit space is shrinking. The high-quality machine-made sand production line can reduce the production cost of concrete and improve the profitability of commercial concrete customers by reducing the amount of cement and improving the quality of sand and gravel, creating favorable conditions for the concrete industry to extend the industrial chain to the sand and gravel industry, and strongly promoting the transformation and upgrading of the commercial concrete industry.
