 Three, to the technical efficiency, in-depth industrial construction. At present, our society as a whole has entered a period of industrialization, some backbone enterprises in the sand and gravel industry has made great achievements in the factory operation, equipment, mechanization level, degree of automation. Industrialization of sand and gravel to more than a few efforts to practice if they caught bad, to some extent can not keep up the pace of industrialization of the society as a whole, can not keep step, step by step to keep up with the future to catch up with industrialized The price paid in the process will be even greater.
