Natural sand is reducing or even disappear in recent years, artificial sand aggregate becomes the major materials for large-scale projects and important  projects such as the Three Gorges Project. We make great efforts to develop infrastructure such as railways, highways, bridges, hydroelectric,  the largest demand is high-quality sand aggregate. Due to different construction standards, the requirements of the material and the discharged material fineness is also different. So, the aggregate production equipment  is divided into impact crusher (sand making machine), jaw crusher,impact crusher, cone crusher, etc. The existing sand resources are limited, continuous mining makes the standard GB sand sharp drop. With the increasingly high building standards, the standard aggregate production also will be improved, this prompted the gravel equipment technology continues to evolve. New sand making machine sand equipment came into being.
With the rapid economic development in recent years, the state strong support infrastructure, such as railways, highways, bridges, hydroelectric construction of the project. These projects can not be separated from the gravel aggregate crushing plant crusher, general infrastructure projects, if with less material, directly from small sand quarry procurement. The vast majority of large-scale projects such as railways, high ways, bridges, hydroelectric project, located in the mountains or deep valleys, narrow construction site, tight construction period, large amount of concrete works, the high strength of concrete construction, strict requirements on the quality of the sand aggregate. Therefore, the design of fine sand with a modern level of technology and dynamic economic indicators equipment and mechanisms of sand production line, to ensure the project will require grading of sand aggregate, in the regulation of the whole project during the construction period dynamic equilibrium production supply is the fundamental purpose of the sand processing plant design.Crushing plant. Crushing workshop selected 4 PL9500SD, design and equipment line speed is 65m / s, the single piece of equipment power 440kW design conditions of a single device to a treatment capacity of 250t / h, workshop processing capacity of 1000t / h, equipment loading rate 83.3%. 
       As the professional crusher manufacturer, Henan Hongxing Heavy Co, make great efforts to develop construction projects for nearly two years at home and abroad. It is stimulating domestic and foreign market demand for sand and gravel aggregate. Great demand of sand and gravel aggregates, brings about aggregate hot selling in production line in the market. Crusher, sand making industry got the support and assistance of national policy in the international and domestic markets. And mining machinery market has been developing rapidly.
