In recent years, with the rapid development of the infrastructure investment and urbanization, the demand of the national aggregate artificial and sand are also in a period of rapid growth. However, the market is a sword, the gravel industry development not only led to the development of related industries, but also brought over-exploitation of resources, environmental pollution these series of problems, which proposed new requirements to our production company, build the high standard production line gravel aggregates, thus promoting the development of modern green industry becomes the most important development of the sand and gravel industry. As to how to carry out the transformation and upgrading of the cement industry, and enhance the development potential. Our company director s pointed out when exploring the upstream gravel aggregate industry chain extension of the cement industry, a sand and gravel aggregate production line must achieve the requirements of high, low, make full use of resources, environmental protection, safety and intelligent these eight factors, then it can be considered as a modern high standard production line. The chairman of our company explain modern gravel production line in respect of its decades of technology and experiences, and conduct these following eight comprehensive scientific commentaries, I have noted: The first point is to let the machine run efficiently. When carrying out the sand production line equipment configuration, it must be reasonable and effective, and to ensure that the production run can run high production efficiency.

The second point is a high quality product. Gravel production line is put into operation, the production of finished products need to achieve a high grade, the high quality good shape. The third point is the low capital investment. Early in the production and construction should be placed on full-scale testing of the chemical analysis of raw materials and metal abrasive, choose a good and reasonable host device, the entire production process layout to be simple, smooth line, to minimize the one – time investment. The fourth point is the low operating costs.which includes the following stems: the lowest operating costs which are invested to gurantee the normal operation of the machine, such as labor cost, shipping cost of sending, and so on; The fifth point is the high utilization of resources.
