Sand and gravel aggregate production line/sand-gravel sand making equipment
The construction of infrastructure such as road traffic is an important aspect of my country's economic construction. The development of the road transportation industry has opened up a huge market for sand and gravel demand, and better highway sand and gravel aggregates will be warmly welcomed by the market.
In road construction, there are many factors that affect the strength of concrete, including the strength of cement, water-cement ratio, aggregate, and admixture, etc. The influence of aggregate is particularly direct. The surface condition of aggregate affects the adhesion between cement stone and aggregate. Therefore, the strength of the concrete is affected; the rough surface of the crushed stone has a large cohesive force; the needle-shaped aggregate has poor strength and low cohesion, while the cube-shaped aggregate greatly improves the performance of the concrete equipment; The particle size also affects the strength of concrete. The larger the particle size of the aggregate, the smaller the strength of the concrete.
Moreover, the natural sand that can be used in infrastructure is decreasing day by day, and it is a wise choice to produce better artificial sand. Because the demand for artificial sand is quite large, some small enterprises without production conditions use simple machinery to produce inferior artificial sand, which not only causes users to pay more costs, but also directly affects the quality of construction projects.
The series of sand making equipment produced by Henan SMMVIK Technology Co. Ltd. has become the core equipment in the machine-made sand industry and stone shaping field. The products have the characteristics of high energy and low consumption and excellent grain shape of finished products, which effectively guarantee the supply of sand and gravel aggregates for expressways, high-speed railways, high-rise buildings, hydropower dams, ports and wharves, and concrete mixing stations.
