With the development of economy, the demand for infrastructure is increasing, such as railways, highways, bridges and other projects. The construction of these projects can not be separated from gravel aggregate. The vast majority of railway, highway, bridges, and other large hydropower station project, narrow construction site, the construction time is tight, concrete engineering capacity, high strength concrete construction quality, the mechanism of sand aggregate is relatively strict. Therefore, to design the fine and economical crushed stone production line it is the basic purpose and requirement of the stone processing production line designing, to ensure the stones and the sand aggregate of the required indexes.

Vigorously develop the railway, highway, bridge and other infrastructure, the largest demand is high-quality gravel, machine-made sand aggregate. Due to the different construction standards, the material and discharge fineness requirements are different, mainly divided into vertical shaft impact crusher (sand making machine), jaw crusher, impact crusher, cone crusher, and so on.

As a Sino-German joint venture corporation, SANDMINE has implanted a strict German standard. All the main components of the crushing and screening machines are fine manufactured in our own factory with strict inspection. SANDMINE VC7, VIC series of vertical shaft impact crusher is a high-quality sand making product which integrates international advanced technology, high efficiency and high reliability. Widely used in metal and non-metallic ore, cement, refractory materials, building aggregate, artificial sand and various metallurgical slag fine crushing and coarse grinding, etc., contribute to the development of infrastructure.
