Aggregate Equipment for Gravel Concrete Suits Express Highway Construction

As for the status of domestic express highway construction, concrete is widely used as the building material. At sand peaks, the supply is not even sufficient which seriously affects the engineering construction progress. With the fast development of concrete technology for express highway, modern highway bridge concrete requires more and higher for sand technology, especially for high intensity and high-level performance concrete. Now the qualified natural sand is less and less and even none, so artificial sand is more and more important in engineering construction and becomes the main resource as building sand material. As a whole, it's imperative to develop the application of artificial sand aggregate powerfully in construction projects.

Henan Hongxing Mining Machinery Co., Ltd. is the professional sand making machinery equipment manufacturer and it can produce and supply high intensity and high-level performance gravel concrete aggregate used for express highway construction.

The Craft of Artificial Gravel Aggregate

Material (such as limestone, granite, and marble) enters into coarse crushing equipment through the feeder machine. The aggregate is crushed for second time after coarse crushing, and then it is screened by screening equipment through belt conveyor and the qualified final aggregate is produced. The needless and improper aggregate enters into sand making machine and then enters into screening plant through rubber belt conveyor. Thus intermediate crushing device, sand making device and screening device form a closed loop which processes the material into final gravel aggregate.

The application and technological craft of new type sand maker is more mature. The inner structure readjusted makes the crusher operation safer and more stable, and also it promotes the productivity and environmental protection. In order to meet for the repaid economic development, large-sale equipment is used more widely. In the standard automatic and environmental situation, all clients prefer to choose crushing equipment with higher efficiency and stronger capacity. Henan Hongxing produces gravel aggregate production equipment of high quality and productivity. Hongxing brand new type sand maker can adopt two feed systems with more simple and safer operation which improves greatly the productivity.
