High quality sand and gravel aggregate production line

In December this year, an annual output of 2000000 tons of fine aggregate in Tianshui production line officially with material production, products are divided into two graded sand (0.075-3mm, 3-4.75mm) and two graded gravel (5-16mm, 16-25mm), then the aggregate output of about 60% will be occupied, aggregate 40% will be invested in the market. High quality concrete aggregate cannot do without high quality, high quality sand aggregate that fine aggregate, fine aggregate used in concrete, can effectively reduce the amount of cement, additives, reasonable gradation in ensuring product quality at the same time, greatly reduce the cost of concrete. Tianshui an annual output of 2000000 tons of fine aggregate production line, the project is the only one selected state-level development zones of fine sand aggregate production line, the production process of energy saving and environmental protection, high degree of automation, design of full closed plant, meet the national environmental protection requirements.

Aggregates as the regional building material, has the characteristics of the short term is not renewable, natural sand gravel, quality has already appeared the phenomenon of the shortage in some areas, even in the face of resource depletion. But the traditional mining industry to the ecological environmental damage is also be obvious to people, which have aroused the attention of governments around the world. Seek new building stone resources imminent, industrialized production mode to explore new environmental protection has become an inevitable. Fine sand aggregate production line put into production in Tianshui, plays a positive role in guiding and promoting mechanism of gravel in Tianshui area application, ease for sand bone without calculating the market situation, the Weihe sand mining, protection of the ecological environment, improve the urban health, promote economic and social development of Tianshui has an extremely important significance. At the same time, help to promote the industry to a high starting point, high standard to guide and encourage the development of building stone mine enterprise, press industry demonstration enterprises, in order to assist, cooperate with the Ministry of land and resources of the "harmony mine construction, mining and processing" regulate behavior, improve the comprehensive utilization of resources, protect the ecological environment, to ensure the safety of production, construction of "green mine", "harmonious mine".
