The medium and Italian fine sand production line makes the building stronger
Zhengzhou Zhongyi mining machine is a large-scale crushing machine manufacturer in China. It has international leading technology level, good after-sales service and high-quality production line configuration plan, and has rich experience in gravel and sand making. In the actual construction of all over the performance of excellent, have been highly recognized by the customer.
The finished sand and aggregate produced by the Sino Italian fine sand production line has the characteristics of fine grain shape, stable gradation, less needle plate-like content, uniform particle size, low stone powder content, high cleanliness and fineness modulus. As we all know, sand aggregate is an important part of concrete. It acts as a skeleton and transfers stress. Even without cement slurry, aggregate can also support load and restrain shrinkage and prevent cracking.
According to the expert analysis of concrete, the reason of poor quality of concrete in China is the poor quality of sand and gravel. Zhengzhou Zhongyi fine sand production line and its launch will break the status quo, specializes in all kinds of bean curd dregs.
It is a problem to improve the quality of sand and gravel aggregate with low quality and large dispersion. The complete sand making production line is generally composed of vibrating feeder, jaw crusher, impact crusher (hard rock cone crusher), sand making machine, sand washing machine, vibrating screen, belt conveyor, centralized electric control and other equipment. If the customers have high requirements for environmental protection, the high efficiency dust removal equipment can be configured at the main inlet and outlet ports, which can effectively control the dust pollution.
Our country has the largest volume of newly built buildings in the world every year. The newly built area is 2 billion square meters per year. The average life span of the world's 40% cement and steel bars is only 25-30 years. There are short life buildings, such as "building crooked", "crisp building", "collapse of the road" and so on.
